Semiclassical dynamics of atomic Bose-Einstein condensates
S. Choi, B. Sundaram
An atomic Bose-Einstein condensate (BEC) is often described as a macroscopic object which can be approximated by a coherent state. This, on the surface, would appear to indicate th…
A nonlinear Ramsey interferometer operating beyond the Heisenberg limit
S. Choi, B. Sundaram
We show that a dynamically evolving two-mode Bose-Einstein condensate (TBEC) with an adiabatic, time-varying Raman coupling maps exactly onto a nonlinear Ramsey interferometer that…
Conditions for the Quantum to Classical Transition: Trajectories vs. Phase Space Distributions
Benjamin D. Greenbaum, Kurt Jacobs, Bala Sundaram
We contrast two sets of conditions that govern the transition in which classical dynamics emerges from the evolution of a quantum system. The first was derived by considering the t…
Semiclassics of the Chaotic Quantum-Classical Transition
Benjamin D. Greenbaum, Salman Habib, Kosuke Shizume +1
We elucidate the basic physical mechanisms responsible for the quantum-classical transition in one-dimensional, bounded chaotic systems subject to unconditioned environmental inter…
Field-induced phases of an orientable charged particle in a dilute background of point charges
Carlo Lancellotti, Bala Sundaram
We study a dynamical model of a rod-like particle surrounded by a cloud of smaller particles of the same charge and we show that, in the presence of a low-frequency alternating ele…
Chaos and Quantum Mechanics
Salman Habib, Tanmoy Bhattacharya, Benjamin Greenbaum +3
The relationship between chaos and quantum mechanics has been somewhat uneasy -- even stormy, in the minds of some people. However, much of the confusion may stem from inappropriat…
