We investigate spin-and valley-symmetry-broken fractional quantum Hall phases within a
formalism that naturally extends the paradigm of quantum Hall ferromagnetism from integer …

The fractional quantum Hall (FQH) effect gives rise to abundant topological phases,
presenting an ultimate platform for studying the transport of edge states. Generic FQH edge …

We study the phase diagram of an extended parafermion chain, which, in addition to terms
coupling parafermions on neighbouring sites, also possesses terms involving four sites. Via …

Controlling spin current in topological insulators (TIs) is a crucial requirement for
applications in quantum computing and spintronics. Using the non-equilibrium Keldysh …

Understanding topological matter in the fractional quantum Hall (FQH) effect requires
identifying the nature of edge state quasiparticles. FQH edge state at the filling factor $\nu …

We demonstrate that non-Hermitian perturbations can probe topological phase transitions
and unambiguously detect non-Abelian zero modes. We show that under carefully designed …

Abstract The Unruh-DeWitt particle detector model has found success in demonstrating
quantum information channels with non-zero channel capacity between qubits and quantum …

The edges of quantum Hall phases give rise to a multitude of exotic modes supporting
quasiparticles of different values of charge and quantum statistics. Among these are …

It has been realized that a p-wave order parameter can emerge in a synthetic
superconductor constructed from a semiconductor and an s-wave superconductor, provided …

The relativistic charge carriers in monolayer graphene can be manipulated in manners akin
to conventional optics (electron-optics): angle-dependent Klein tunneling collimates an …
