Topological analog of the magnetic bit within the Su-Schrieffer-Heeger-Holstein model
Xinyuan Xu, David Sénéchal, Ion Garate
In magnetic memories, the state of a ferromagnet is encoded in the orientation of its magnetization. The energy of the system is minimized when the magnetization is parallel or ant…
Detection of phonon helicity in nonchiral crystals with Raman scattering
Selçuk Parlak, Sayandip Ghosh, Ion Garate
Recently, it has been predicted that the Berry curvature of electrons can produce an angular momentum for phonons. In systems with time-reversal symmetry, the direction of the phon…
Unconventional Resistivity Scaling in Topological Semimetal CoSi
Shang-Wei Lien, Ion Garate, Utkarsh Bajpai +9
Nontrivial band topologies in semimetals lead to robust surface states that can contribute dominantly to the total conduction. This may result in reduced resistivity with decreasin…
Van Roosbroeck's equations with topological terms: the case of Weyl semimetals
Pierre-Antoine Graham, Simon Bertrand, Michaël Bédard +2
Van Roosbroeck's equations constitute a versatile tool to determine the dynamics of electrons under time- and space-dependent perturbations. Extensively utilized in ordinary semico…
Size-Dependent Grain Boundary Scattering in Topological Semimetals
Nicholas A. Lanzillo, Utkarsh Bajpai, Ion Garate +1
We assess the viability of topological semimetals for application in advanced interconnect technology, where conductor size is on the order of a few nanometers and grain boundaries…
Theory of phonon instabilities in Weyl semimetals at high magnetic fields
Sarbajaya Kundu, Claude Bourbonnais, Ion Garate
The behavior of three-dimensional (3D) semimetals under strong magnetic fields is a topic of recurring interest in condensed matter physics. Recently, the advent of Weyl and Dirac…
