Thomas Allison: Mastering the Electromagnetic Spectrum

Most of what we associate with the word “technology” derives from our ever increasing ability to control electromagnetic fields. From the early days of telephone and radio communication to the current era of the internet and GHz microprocessors, physicists and engineers have worked relentlessly to produce and utilize electromagnetic fields of higher frequencies and larger coherent bandwidths. In this talk, I will discuss how now physicists can control light waves and even x-rays using a new type of laser called a frequency comb. Frequency combs now allow us to build the most precise atomic clocks and generate attosecond pulses of soft x-rays - the shortest manmade events - pushing the boundaries of what scientists can measure.

Prof. Allison holds a joint appointment with the departments of Physics and Chemistry at Stony Brook University since 2013. His research group studies frequency comb lasers, ultrafast dynamics, and strong-field atomic physics. Prof. Allison is a recent recipient of the prestigious Early Career Award granted by the Department of Energy who has recognized his work on developing new light sources and techniques to follow the motions of molecular systems in real-time.

Sriram Ganeshan: How whole is more than the sum of its parts in Physics

Indistinguishable nature of particles is one of the hallmarks of quantum physics. However, millions of such indistinguishable entities come together to yield distinct features that constitute the world we see around us. To motivate this discussion, Prof. Ganeshan would urge the audience to come up with everyday things that they think are indistinguishable! He would briefly outline how physicists attempt to understand the underlying principles of similar particles coming together in a crowd and end up losing their identity as an individual.

Sriram Ganeshan is a Ph.d. graduate of Stony Brook University with a Postdoctoral Research position held at University of Maryland. He joined the Simons Center for Geometry and Physics as a Research Assistant Professor in 2015.

Dominik Schneble: Ultracold atoms and Bose-Einstein condensates

Experimental methods to cool neutral atoms to nanokelvins make it possible to observe quantum-mechanical effects with (almost) the naked eye. One of the most spectacular achievements of the past two decades has been the direct observation of Bose-Einstein condensation in trapped atomic gases. Bose-Einstein condensates, in which all atoms occupy the same quantum state and form a giant matter wave, have allowed for a plethora of investigations such as atom lasers, vortices, superfluidity, and superradiance. Bosonic and fermionic quantum gases, and advanced techniques for their manipulation, now allow researchers to address questions throughout modern physics, ranging from correlated behavior of electrons in solids to the physics of neutron stars. This talk will give an introduction to this thriving field, and highlight some of research done in our own laboratory.

Dominik Schneble is an Associate Professor and leader of the Ultracold Atomic Physics Group at Stony Brook University. He obtained his PhD from the University of Konstanz in 2002 and worked as a Postdoctoral Associate at MIT, before joining Stony Brook in 2005.
