Quantum Brownian Motion of a Macroscopic Object in a General Environment
Chung-Hsien Chou, B. L. Hu, Ting Yu
For the purpose of understanding the quantum behavior such as quantum decoherence, fluctuations, dissipation, entanglement and teleportation of a mesoscopic or macroscopic object i…
Many-Body Separability of Warm Qubits
Ting Yu, J. H. Eberly
We analyze the separability of the joint state of a collection of two-level systems at finite temperature T. The fact that only separable states are found in the neighborhood of th…
Negative Entanglement Measure, and What It Implies
Ting Yu, J. H. Eberly
In this paper, we extract from concurrence its variable part, denoted , and use as a time-dependent measure of "distance", either postive or negative, from the separability…
Exact Master Equation and Quantum Decoherence of Two Coupled Harmonic Oscillators in a General Environment
Chung-Hsien Chou, Ting Yu, B. L. Hu
In this paper we derive an exact master equation for two coupled quantum harmonic oscillators interacting via bilinear coupling with a common environment at arbitrary temperature m…
