Ehrenfest approach to open double-well dynamics
Stephen Choi, Roberto Onofrio, Bala Sundaram
We consider an Ehrenfest approximation for a particle in a double-well potential in the presence of an external environment schematized as a finite resource heat bath. This allows…
A quantum description of bubble growth in a superheated fluid
S. Choi, K. M. Galdamez, B. Sundaram
We discuss a quantum description of bubble growth in a superheated liquid Helium by addressing the problem of operator ordering ambiguities that arise due to the presence of positi…
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…
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…
Nonlinear Quantum Dynamics
Salman Habib, Tanmoy Bhattacharya, Andrew Doherty +8
The vast majority of the literature dealing with quantum dynamics is concerned with linear evolution of the wave function or the density matrix. A complete dynamical description re…
