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…
Local Current Distribution and "Hot Spots" in the Integer Quantum Hall Regime
Y. Dubi, Y. Meir, Y. Avishai
In a recent experiment, the local current distribution of a two-dimensional electron gas in the quantum Hall regime was probed by measuring the variation of the conductance due to…
A unifying model for several two-dimensional phase transitions
Yonatan Dubi, Yigal Meir, Yshai Avishai
A relatively simple and physically transparent model based on quantum percolation and dephasing is employed to construct a global phase diagram which encodes and unifies the critic…
Quantum Hall Criticality, Superconductor-Insulator Transition and Quantum Percolation
Yonatan Dubi, Yigal Meir, Yshai Avishai
A model consisting of a mixture of superconducting and quantum links is proposed to describe the integer quantum Hall transition. The quantum links correspond to tunneling of elect…
