Tunable magnons in a dual-gated 2D antiferromagnet
Nele Stetzuhn, Abhijeet M. Kumar, Sviatoslav Kovalchuk +12
The layered antiferromagnet CrSBr features magnons coupled to other quasiparticles, including excitons and polaritons, enabling their easy optical accessibility. In this work, we i…
Topology of ultra-localized insulators and superconductors
Bastien Lapierre, Luka Trifunovic, Titus Neupert +1
The topology of an insulator can be defined even when all eigenstates of the system are localized - an extreme case of Anderson insulators that we call ultra-localized. We derive t…
Mesoscopic fluctuations of the ground state spin of a small metal particle
P. W. Brouwer, Yuval Oreg, B. I. Halperin
We study the statistical distribution of the ground state spin for an ensemble of small metallic grains, using a random-matrix toy model. Using the Hartree Fock approximation, we f…
