Flux-dependent occupations and occupation difference in geometrically symmetric and energy degenerate double-dot Aharonov-Bohm interferometers
Salil Bedkihal, Malay Bandyopadhyay, Dvira Segal
We study the steady-state characteristics and the transient behavior of the nonequilibrium double-dot Aharonov-Bohm interferometer using analytical tools and numerical simulations.…
Ground state cooling is not possible given initial system-thermal bath factorization
Lian-Ao Wu, Dvira Segal, Paul Brumer
In this paper we prove that a fundamental constraint on the cooling dynamic implies that it is impossible to cool, via a unitary system-bath quantum evolution, a system that is emb…
Full density matrix dynamics for large quantum systems: Interactions, Decoherence and Inelastic effects
Manas Kulkarni, Kunal L Tiwari, Dvira Segal
We develop analytical tools and numerical methods for time evolving the total density matrix of the finite-size Anderson model. The model is composed of two finite metal grains, ea…
Exact dynamics of interacting qubits in a thermal environment: Results beyond the weak coupling limit
Lian-Ao Wu, Claire X. Yu, Dvira Segal
We demonstrate an exact mapping of a class of models of two interacting qubits in thermal reservoirs to two separate spin-bath problems. Based on this mapping, exact numerical simu…
Towards equilibration and thermalization between finite quantum systems: The role of dephasing effects and inelastic interactions
Manas Kulkarni, Kunal L. Tiwari, Dvira Segal
We demonstrate the approach towards a Gibbs-like equilibrium state, with a common temperature and a chemical potential, of two finite metallic grains, prepared with a different num…
Amplification of non-Markovian decay due to bound state absorption into continuum
Savannah Garmon, Tomio Petrosky, Lena Simine +1
It is known that quantum systems yield non-exponential (power law) decay on long time scales, associated with continuum threshold effects contributing to the survival probability f…
