Vacuum Decay in Time-Dependent Backgrounds
Patrick Draper, Manthos Karydas, Hao Zhang
We develop semiclassical methods for studying bubble nucleation in models with parameters that vary slowly in time. Introducing a more general rotation of the time contour allows a…

Spin wave Hamiltonian and anomalous scattering in NiPS
A. Scheie, Pyeongjae Park, J. W. Villanova +8
We report a comprehensive spin wave analysis of the semiconducting honeycomb van der Waal antiferromagnet NiPS. Using single crystal inelastic neutron scattering, we map out th…

Anatomy of topological Anderson transitions
Hao Zhang, Alex Kamenev
We study mesoscopic signatures of the topological Anderson transitions in topological disordered chains. To this end we introduce an integer-valued sample-specific definition of th…
