The Position Space Chern Number: A Topological Index for Chiral Magnetic Systems
Zachariah Addison
This paper introduces an index that categorizes the topology of insulating chiral magnetic systems. The position space Chern number, is distinct from its momentum space count…

Local Hall Conductivity in Disordered Topological Insulators
Zachariah Addison, Nandini Trivedi
We derive the expression for the local Hall conductivity for systems that lack translation symmetry and use it to study the local fluctuations of the Hall signal around disordered…

Anomalous and Topological Hall Effects with Phase-Space Berry Curvatures: Electric, Thermal, and Thermoelectric Transport in Magnets
Zachariah Addison, Lauren Keyes, Mohit Randeria
We develop a theory for the electrical and thermal transverse linear response functions such as the Hall, Nernst and thermal Hall effects in magnetic materials that harbor topologi…
