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…
Ehrenfest Dynamics and Frictionless Cooling Methods
S. Choi, R. Onofrio, B. Sundaram
Recently introduced methods which result in shortcuts to adiabaticity, particularly in the context of frictionless cooling, are rederived and discussed in the framework of an appro…
Optimized sympathetic cooling of atomic mixtures via fast adiabatic strategies
Stephen Choi, Roberto Onofrio, Bala Sundaram
We discuss fast frictionless cooling techniques in the framework of sympathetic cooling of cold atomic mixtures. It is argued that optimal cooling of an atomic species - in which t…
Nonlinear Response Functions of Strongly Correlated Boson Fields: Bose-Einstein Condensates and Fractional Quantum Hall Systems
S. Choi, O. Berman, V. Chernyak +1
The second order response functions and susceptibilities of finite temperature Bose-Einstein Condensates (BEC) in a one dimensional harmonic trap driven by an external field that c…
Mechanical response functions of finite temperature Bose-Einstein Condensates
S. Choi, V. Chernyak, S. Mukamel
Using the Liouville space framework developed in nonlinear optics we calculate the linear response functions and susceptibilities of Bose-Einstein condensates (BEC) subject to an a…
