Thermalization-Induced Entropy-Rate Representation of Internal Energy in a Damped Quantum Oscillator
Hyeong-Chan Kim, Youngone Lee
We study a harmonic oscillator weakly coupled to a thermal bath and evolving under the standard quantum-optical master equation. For zero-mean Gaussian states, entropy alone does n…
Heat conduction in general relativity
Hyeong-Chan Kim, Youngone Lee
We study the problem of heat conduction in general relativity by using Carter's variational formulation. We write the creation rates of the entropy and the particle as combinations…
Charged Rotating Black Hole with an Anisotropic Matter Field: Solution of the Maxwell Field
Hyeong-Chan Kim, Bum-Hoon Lee, Wonwoo Lee +1
We study a rotating black hole with anisotropic matter and electromagnetic fields. We show that the electromagnetic field has the same form as the corresponding one in the Kerr-New…
Quantum harmonic oscillators and thermalization
Hyeong-Chan Kim, Youngone Lee
We study a quantum harmonic oscillator undergoing thermalization. To describe the thermalization process, we generalize the Ermakov-Lewis-Riesenfeld (ELR) invariant method for the…
Local temperature in general relativity
Hyeong-Chan Kim, Youngone Lee
We examine the Tolman temperature by using Carter's variational formalism of thermodynamics. We restrict our interests to fluids in thermal equilibrium that the heat does not propa…
Nonadiabaticity of Quantum harmonic oscillators
Hyeong-Chan Kim, Youngone Lee
We propose a quantity, , as a measure describing the nonadiabaticity of a thermodynamic process. For this purpose, we use a schematic method to find the measu…
