Theory of Topological Nernst and Thermoelectric Transport in Chiral Magnets
Zachariah Addison, Lauren Keyes, Mohit Randeria
We calculate the thermoelectric transport of spin-orbit coupled conduction electrons in the presence of topological spin textures. We show, within a controlled, semiclassical appro…
Unified Theory of the Anomalous and Topological Hall Effects with Phase Space Berry Curvatures
Nishchhal Verma, Zachariah Addison, Mohit Randeria
Hall experiments in chiral magnets are often analyzed as the sum of an anomalous Hall effect, dominated by momentum-space Berry curvature, and a topological Hall effect, arising fr…
Strange metal behavior of the Hall angle in twisted bilayer graphene
Rui Lyu, Zachary Tuchfeld, Nishchhal Verma +6
Twisted bilayer graphene (TBG) with interlayer twist angles near the magic angle hosts flat bands and exhibits correlated states including Mott-like insulato…
Atomic scale visualization of topological spin textures in the chiral magnet MnGe
Jacob Repicky, Po-Kuan Wu, Tao Liu +8
Spin polarized scanning tunneling microscopy is used to directly image topological magnetic textures in thin films of MnGe, and to correlate the magnetism with structure probed at…
