Bulk Topological Proximity Effect
Timothy H. Hsieh, Hiroaki Ishizuka, Leon Balents +1
Existing proximity effects stem from systems with a local order parameter, such as a local magnetic moment or a local superconducting pairing amplitude. Here, we demonstrate that d…
Kinetic Magnetism at the Interface Between Mott and Band Insulators
Jason Iaconis, Hiroaki Ishizuka, D. N. Sheng +1
We show that the interplay of a high density two-dimensional electron gas and localized electrons in a neighboring Mott insulator leads to kinetic magnetism unique to the Mott/band…
"Switching" of Magnetic Anisotropy in a fcc Antiferromagnet with Direction-Dependent Interactions
Hiroaki Ishizuka, Leon Balents
Direction-dependent anisotropic exchange is a common feature of magnetic systems with strong spin-orbit coupling. Here we study the effect of such exchange upon macroscopic magneti…
A strong coupling theory for electron-mediated interactions in double-exchange models
Hiroaki Ishizuka, Yukitoshi Motome
We present a theoretical framework for evaluating effective interactions between localized spins mediated by itinerant electrons in double-exchange models. Performing the expansion…
