Physics Seminar: Quantum Optics, Some Past and Present Trends

N-823

Place: Namm 823 April 30 at 12:00 pm Presented by Prof. Mark Hillery Faculty and students are welcome. Abstract: Quantum optics arose with the invention of the laser. Early work focussed on developing a quantum theory of the laser and on better understanding the nature of the quantized electromagnetic field. It was for this latter

Physics Seminar: Pattern Formation and Strong Nonlinear Interactions in Exciton-Polariton Condensates

N-823

Place: Namm 823 Date: Thursday October 22, 2015 Time: 12:00 p.m. Presented by Dr. Li Ge Faculty and students are welcome, light refreshments will be served. Abstract: Exciton-polaritons generated by light-induced potentials can spontaneously condense into macroscopic quantum states that display nontrivial spatial and temporal density modulation. While these patterns and their dynamics can be reproduced

Initiative for Interstellar Studies, UK: Kevin F. Long presents Interstellar Flight: The Perspective of Theoretical Physics

N-816 NY

The quest for the stars is an inspiring one that promises discoveries and new knowledge that has profound implications for our view of the Universe. Yet, to travel to the stars apparently requires breakthroughs in our physics and engineering knowhow. In this presentation, we examine the problem from the stand point of theoretical physics and

The Physics Department presents An information theoretic approach to quantify complexity of nanoscale systems by Dr. Ilya Grigorenko

N-823

Abstract: In this study the entropy density and mutual information measures were used to identify the optimal interaction parameters between nanoparticles, which lead to the maximum geometric complexity of self-assembled nanostructures. A generalization of complexity measures at a finite temperature and for nonequilibrium systems is also presented. The developed theory can be used for efficient in

Physics Seminar: Prof. William Wootters:
Why does nature like the square root of negative one?

N-823

Place: Namm 823 Date: Thursday, March 31 2016 Time: 12:00 PM   Presented by Prof. William Wootters Faculty and students are welcome.   Abstract: Quantum mechanics is a probabilistic theory, but the way we compute probabilities in quantum mechanics is quite different from what one would expect from, say, rolling dice or tossing coins.  To get a quantum probability,
