Exact Ionization Amplitudes for a Delta-Function Well in an Arbitrary-Strength DC Electric Field
Ilki Kim, Gerald J. Iafrate
We investigate finite-time field-induced ionization from a one-dimensional attractive delta-function well in a uniform dc electric field of arbitrary strength. Our aim is to determ…
Quantal-classical fluctuation relation and the second law of thermodynamics: The quantum linear oscillator
Ilki Kim
In this work, we study the fluctuation relation and the second law of thermodynamics within a quantum linear oscillator externally driven over the period of time t = tau. To go bey…
Non-negative Wigner-like distributions and Renyi-Wigner entropies of arbitrary non-Gaussian quantum states: The thermal state of the one-dimensional box problem
Ilki Kim
In this work, we consider the phase-space picture of quantum mechanics. We then introduce non-negative Wigner-like (operational) distributions \widetilde{\mathcal W}_{rho;alpha}(x,…
Renyi-alpha entropies of quantum states in closed form: Gaussian states and a class of non-Gaussian states
Ilki Kim
In this work, we study the Renyi-alpha entropies S_{alpha}(\hat{rho}) = (1 - alpha)^{-1} \ln{Tr(\hat{rho}^{alpha})} of quantum states for N bosons in the phase-space representation…
Endo-reversible heat engines coupled to finite thermal reservoirs: A rigorous treatment
Ilki Kim, Hui Wan, Soumya S. Patnaik
We consider two specific thermodynamic cycles of engine operating in a finite time coupled to two thermal reservoirs with a finite heat capacity: The Carnot-type cycle and the Lore…
Ab initio relaxation times and time-dependent Hamiltonians within the steepest-entropy-ascent quantum thermodynamic framework
ILki Kim, Michael R. von Spakovsky
Quantum systems driven by time-dependent Hamiltonians are considered here within the framework of steepest-entropy-ascent quantum thermodynamics (SEAQT) and used to study the therm…
