Quantum interference and exceptional points
Stefano Longhi
Exceptional points (EPs), i.e. branch point singularities of non-Hermitian Hamiltonians, are ubiquitous in optics. So far, the signatures of EPs have been mostly studied assuming c…
symmetry and anti-symmetry by anti-Hermitian wave coupling and nonlinear optical interactions
Stefano Longhi
Light propagation in systems with anti-Hermitian coupling, described by a spinor-like wave equation, provides a general route for the observation of anti parity-time ($\mathcal{PT}…
Presence of temporal dynamical instabilities in topological insulator lasers
S. Longhi, Y. Kominis, V. Kovanis
Topological insulator lasers are a newly introduced kind of lasers in which light snakes around a cavity without scattering. Like for an electron current in a topological insulator…
Coherent virtual absorption for discretized light
Stefano Longhi
Coherent virtual absorption (CVA) is a recently-introduced phenomenon for which exponentially growing waves incident onto a conservative optical medium are neither reflected nor tr…
