A third-order exceptional point effect on the dynamics of a single particle in a time-dependent harmonic trap
Raam Uzdin, Emanuele Dalla Torre, Ronnie Kosloff +1
The time evolution of a single particle in a harmonic trap with time dependent frequency omega(t) is well studied. Nevertheless here we show that, when the harmonic trap is opened…
Comments on "Cooling by Heating: Refrigerator Powered by Photons"
Amikam Levy, Robert Alicki, Ronnie Kosloff
We comment that the model proposed in Phys. Rev. Lett. 108, 120603 (2012) violates the dynamical version of the third law of thermodynamics. We discuses the different formulations…
Optimal control theory of harmonic generation
Ido Schaefer, Ronnie Kosloff
Coherent control of harmonic generation was studied theoretically. A specific harmonic order was targeted. An optimal control theory was employed to find the driving field where re…
Quantum Refrigerator and the III-law of Thermodynamics
Amikam Levy, Robert Alicki, Ronnie Kosloff
The rate of temperature decrease of a cooled quantum bath is studied as its temperature is reduced to the absolute zero. The III-law of thermodynamics is then quantified dynamicall…
Short Time Cycles of Purely Quantum Refrigerators
Tova Feldmann, Ronnie Kosloff
Four stroke Otto refrigerator cycles with no classical analogue are studied. Extremely short cycle times with respect to the internal time scale of the working medium characterize…
New, Highly Accurate Propagator for the Linear and Nonlinear Schrödinger Equation
Hillel Tal-Ezer, Ronnie Kosloff, Ido Schaefer
A propagation method for the time dependent Schrödinger equation was studied leading to a general scheme of solving ode type equations. Standard space discretization of time-depend…
