Thermoelectric effects of an Aharonov-Bohm interferometer with an embedded quantum dot in the Kondo regime
Tae-Suk Kim, S. Hershfield
Thermoelectric effects are studied in an Aharonov-Bohm (AB) interferometer with an embedded quantum dot in the Kondo regime. The AB flux-dependent transmission probability has an a…
Effects of signs in tunneling matrix elements on transmission zeros and phase
Tae-Suk Kim, S. Hershfield
The effect of the signs in the tunneling matrix elements on the transmission zeros and the transmission phase in transport through a quantum dot is studied. The existence of the tr…
A Theoretical Search for the Optimum Giant Magnetoresistance
Tat-Sang Choy, Jian Chen, Selman Hershfield
The maximum current-perpendicular-to-plane giant magnetoresistance is searched for in magnetic multilayers made of Co, Ni, and Cu with disorder levels similar to those found in roo…
Calculation of Giant Magnetoresistance in Laterally Confined Multilayers
Kingshuk Majumdar, Jian Chen, Selman Hershfield
We have studied the Giant Magnetoresistance (GMR) for laterally confined multilayers, e.g., layers of wires, using the classical Boltzmann equation in the current-in-plane (CIP) ge…
