|2015 Nobel Prize in Physics for the dicovery of neutrino oscillations|
This year's Nobel Prize
was awared to Takaaki Kajita, Super-Kamiokande Collaboration,
U. of Tokyo, Japan and Art McDonald, SNO collaboration, Queen’s University,
Canada for the discovery of neutrino oscillations.
Prof. Kajita was one of the leaders of the Super-Kamiokande Collaboration that constructed the maginificent 50-kton Super-Kamiokande water Cherenkov detector. The experiment discovered "Oscillation of Atmospheric Neutrinos" in 1998 that had far reaching impact on the particle physics. The discovery is the only experimental evidence in laboratory venue for physics beyond the Standard Model today.
The Stony Brook Nucleon decay and Neutrino (NN) group established by Prof. Chang Kee Jung participated in the Super-Kamiokande experiment since 1991 from the beginning of the experiment. The group contributed significantly to the experiment by being a part of the team that constructed detector and analyzed the atmospheric neutrino data. The orignal members of the NN group include, Prof. Clark McGrew and Prof. Chiaki Yanagisawa, and many postdocs and graduate students. The current Super-Kamiokande members from the NN group include Prof. Michael Wilking.
The Stony Brook NN group also played a leading role in the K2K experiment, the first long baseline neutrino oscillation experiment that confirmed the neutrino oscillation observed by the Super-Kamiokande experiment and the T2K experiment that discovered electron neutrino appearance from a muon neutrino beam in 2013.
|Samantha Scibelli is URECA's September Researcher of the Month|
A Women in Science & Engineering (WISE) junior majoring in both Physics and Astronomy, Samantha has long held a deep passion for these fields.
Since last December, Samantha has been doing astrophysics research with Dr. Rosalba Perna (Stony Brook University, Physics & Astronmy) & Dr. Charles Keeton (Rutgers University, Physics & Astronomy) on dark matter, spiral galaxies and gravitational lensing. Her research project was funded by the PSEG Explorations in STEM program for summer 2015, a 10-week summer research program co-administered by Technology & Society, the Career Center and URECA that includes professional development activities as well as a focus on research, and culminated in a poster symposium event this past August. Samantha had previously engaged in optics research projects at the Laser Teaching Center, starting in the summer before freshman year, working under the mentorship of Dr. John Noé. She has presented posters at the URECA campus wide symposia (2014, 2015); as well as the 2013 Frontiers in Optics, OSA Annual Meeting in Florida where she presented "A study of Evolving Caustics Formed by Evaporating Water Droplets."
Born in Saratoga Springs, and a graduate of Burnt Hills-Ballston Lake High School, Samantha embarked on a long-term astronomy research project starting in her sophomore year of high school working at Rensselaer Polytechnic Institute: Samantha analyzed over 10,000 spectra by eye in the Sloan Digital Sky Survey and found a selection of stars that were not correctly classified by the electronic matching system, work for which she was recognized with an Intel STS finalist award, and which was published in the Astrophysical Journal Supplement series (Census of Blue Stars in the SDSS, ApJS 215 24, Dec. 2014).
Samantha's long term goals include getting a PhD in Astronomy. Her hobbies at SB include participating in the Astronomy Club, doing science outreach and playing club field hockey. (read more)
|Dhruv Dixit Named Goldwater Scholar|
Congratualtions to physics and mathematics major Dhruv Dixit for being named a 2015 Goldwater Scholar.
Dhruv is member of Stony Brook University's Honors College. He is only the 34th Goldwater Scholar honoree in Stony Brook since 1992. The award is among the most prestigious honors given nationally to college undergraduate students.
Dhruv is originally from Gujarat, India. He works at the PHENIX detector with Tom Hemmick, Abhay Deshpande and Axel Drees at Brookhaven National Laboratory's Relativistic Heavy Ion Collider. The high-energy collisions produced at RHIC give rise to a super-hot quark-gluon plasma, and the study of the properties of this plasma is crucial for testing the Standard Model of particle physics. Dhruv will participate in the analysis of the data currently being collected at RHIC.
Dhruv is planning to seek a PhD in physics following graduation.
|Paper led by Mathew Madhavacheril and Neelima Sehgal selected as an Editor's Suggestion in Phys. Rev. Letters.|
A paper led by Neelima Sehgal and her graduate student
Mathew Madhavacheril for the Atacama Cosmology Telescope (ACTPol) Collaboration has just been published in PRL
and it was selected as an Editor's Suggestion. It is also featured in with a Viewpoint article in Physics (dated April 13).
The collaboration studied the effects of gravitational lensing on the Cosmic Microwave Background (CMB). The data were collected by the ACTpol telescope, operating in the Chilean Atacama Desert. They measured, statistically, distortions in the CMB hot and cold spots caused by the gravitational pull of massive galaxies or the galaxy clusters. To eliminate the noise in the CMB the authors used a stacking technique, averaging together small images centered at the positions of known galaxies. Nearly 12,000 optically selected galaxies from the SDSS/BOSS survey have been used.
Using he CMB as the background source offers some interesting advantages, as the time and the statistical properties of the CMB’s emission are very well known. The CMB also comes to us from all directions and can be available for many more objects of interest.
Please note that Tom Allison is also featured in Physics (Synopsis, dated April 14), as the co-author of a paper on "Cavity-Enhanced Field-Free Molecular Alignment at a High Repetition Rate".
|Lukasz Fidkowski received a Sloan Fellowship|
Lukasz Fidkowski recevied a 2015 Sloan Research Fellowship. He is one of the 126 recipients this year; 24 of the Fellowships were awarded in Physics,
Lukasz was selected for his research in theoretical condensed matter physics. In particular, he developed a classification of topological phases in one dimension, he carried out a calculation of the entanglement spectrum of topological insulators and superconductors, and he suggested the existence of the Majorana zero modes in one-dimensional quantum wires. His discoveries extend and deepen our current understanding of the ordered states of matter and help uncover new properties of matter. Some of these properties may have useful applications, such as encoding quantum information, making it possible to use them as the building blocks of a quantum computer.
Lukasz joined Stony Brook in 2013. He received his BS in mathematics from Harvard University in 2001 and PhD in physics from Stanford University in 2007. He was a postdoctoral scholar at the California Institute of Technology and a researcher at Microsoft's Station Q, a research lab focused on studies of topological quantum computing. He has made important contributions to the field of topological insulators. - See more at: here

|Abhay Deshpande and Rosalba Perna has been elected Fellows of the American Physical Society|
Congratulations to Abhay Deshpande and Rosalba Perna for being elected Fellows of the American Physical Society (APS).
APS fellowships are awarded after extensive review and each year no more than one-half of one percent of APS membership can be elected as a fellow.
Rosalba's primary area of research is theoretical high-energy astrophysics, including studies of gamma-ray bursts and of highly magnetized neutron stars, known as 'magnetars'. She is a member of several international collaborations aimed at understanding the physics of matter in extreme conditions. Her research has received numerous grants from both NASA and the National Science Foundation. She was honored for her "for her pioneering contributions to our understanding of the long and short gamma-ray bursts, including the development of advanced models to describe their properties and environments, calculations of their particle and radiative emission, and innovative treatment of the time-dependent photo-ionization in the dusty environment around the bursts."
Abhay's research has focused on exploring and understanding quantum chromodynamics (QCD), a fundamental force describing the interactions between quarks and gluons which make up hadrons such as the proton, neutron, and pion. He is also a Senior Fellow and Deputy Group Leader for Experiments at the RIKEN (Japan's Institute of Physical and Chemical Research) BNL (Brookhaven National Laboratory) Research Center, located at BNL. His research is currently supported by the US Department of Energy, Office of Nuclear Science & RIKEN. He was elected "for his sustained effort and leadership in experimental programs to understand the nucleons’ spin, employing polarized DIS experiments at CERN to high-energy polarized proton collisions at RHIC (with PHENIX detector), including early development of beam polarimetry and other essential tools; and for his leadership in the efforts toward realizing the future US electron ion collider."

|Proton Spin Dissected|
Recent papers by the Phenix
and the STAR collaborations, and
of the data conclusively
indicate that about 20-30% of the proton spin is due to gluons.
The new precision measurements at the Relativistic Heavy Ion Collider (RHIC) in Brookhaven National Laboratory based on data collection runs by the two experiments in 2009. The analysis of the proton spin was made possible by RHIC's unique capability of colliding polarized protons. According to Abhay Deshpande "the contribution of the gluons is about the same as the contribution of the quarks, 15%, measured at CERN in the 1990's. The remainder is due to the orbital motion of gluons and quarks. While there is evidence from transverse spin effects for the orbital motion, it can be only measured if we build the electron-ion collider (EIC) that is currently in the planning stage. Once EIC measures the orbital component directly we will have a complete understanding of the composition of the nucleon spin."
Kieran Boyle (currently a Riken BNL Research Center Fellow) and Andrew Manion (currently a postdoc at Lawrence Berkeley Laboratory) did the main data analysis for Phenix results during the time when they were graduate students in our Department.
