Nonlocal Orbital-Angular-Momentum Dichroism of Vortex Light in Strained Crystals
Habib Rostami
Vortex light carries orbital angular momentum (OAM) in its transverse phase. We show that the transverse phase cannot generate OAM-odd absorption in any continuously translation-in…
Robustness against disorder in topological fibre lasers with explicitly broken PT symmetry
Brook Salter, Nathan Roberts, Habib Rostami +2
Fibre lasers realise a large gain medium in a compactly coiled fibre. Disorder due to fabrication can negatively impact the stability of their lasing modes, especially in multi-cor…
Fermi liquid theory of -wave altermagnets: demon modes and Fano-demon states
Habib Rostami, Johannes Hofmann
We develop a Fermi liquid theory of -wave altermagnets and apply it to describe their collective excitation spectrum. We predict that in addition to a conventional undamped plas…
Magnetic field suppression of tomographic electron transport
Habib Rostami, Nitay Ben-Shachar, Sergej Moroz +1
Degenerate two-dimensional electron liquids are theoretically established to possess two vastly distinct collisional electron mean free paths, where even-parity deformations of the…
Fate of surface gaps in magnetic topological insulators
Habib Rostami, Ali G. Moghaddam
In magnetic topological insulators, the surface states can exhibit a gap due to the breaking of time-reversal symmetry. Various experiments, while suggesting the existence of the s…
Nonlinear thermoelectric probes of anomalous electron lifetimes in topological Fermi liquids
Johannes Hofmann, Habib Rostami
In two-dimensional Fermi liquids (FLs), odd-parity Fermi surface deformations have anomalously slow relaxation rates that are suppressed as with temperature , distinct fro…
