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…
Rapidly-oscillating scatteringless non-Hermitian potentials and the absence of Kapitza stabilization
Stefano Longhi
In the framework of the ordinary non-relativistic quantum mechanics, it is known that a quantum particle in a rapidly-oscillating bound potential with vanishing time average can be…
Photonic Loschmidt echo in binary waveguide lattices
Stefano Longhi
Time reversal is one of the most intriguing yet elusive wave phenomenon of major interest in different areas of classical and quantum physics. Time reversal requires in principle t…
