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…
Magneto-optical Kerr effect and signature of the chiral anomaly in a Weyl semimetal in a magnetic field
Jean-Michel Parent, René Côté, Ion Garate
One striking property of the Landau level spectrum of a Weyl semimetal (WSM) is the existence of a chiral Landau level, in which the electrons propagate unidirectionally along the…
Phonon magnetochiral effect of band-geometric origin in Weyl semimetals
Sanghita Sengupta, M. Nabil Y. Lhachemi, Ion Garate
The phonon magnetochiral effect consists of a nonreciprocity in the velocity or attenuation of acoustic waves when they propagate parallel and antiparallel to an external magnetic…
Complete optical valley polarization in Weyl semimetals in strong magnetic fields
Simon Bertrand, Jean-Michel Parent, René Côté +1
We present a theory of an optically induced valley polarization in an interacting, time-reversal symmetric Weyl semimetal placed under strong magnetic fields. Because the applicati…
