Fourier's Law: insight from a simple derivation
Y. Dubi, M. Di Ventra
The onset of Fourier's law in a one-dimensional quantum system is addressed via a simple model of weakly coupled quantum systems in contact with thermal baths at their edges. Using…
Thermo-spin effects in a quantum dot connected to ferromagnetic leads
Y. Dubi, M. Di Ventra
We study a system composed of a quantum dot in contact with ferromagnetic leads, held at different temperatures. Spin analogues to the thermopower and thermoelectric figures of mer…
Signature of persistent metallic domains in FORC measurements of the VO metal-insulator transition
J. -G. Ramírez, A. Sharoni, Y. Dubi +2
We have performed first order reversal curve measurements of the temperature-driven metal-insulator transition in VO thin films, which enable quantitative analysis of the hyste…
Reconstructing Fourier's law from disorder in quantum wires
Y. Dubi, Y. Di Ventra
The theory of open quantum systems is used to study the local temperature and heat currents in metallic nanowires connected to leads at different temperatures. We show that for bal…
Relaxation times in an open interacting two-qubit system
Y. Dubi, M. Di Ventra
In a two-qubit system the coupling with an environment affects considerably the entanglement dynamics, and usually leads to the loss of entanglement within a finite time. Since ent…
Information compressibility, entropy production and approach to steady state in open systems
M. Di Ventra, Y. Dubi
We introduce the concept of {\em information compressibility}, , which measures the relative change of number of available microstates of an open system in response to an ener…
