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…
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…
Non-Hermitian time-dependent perturbation theory: asymmetric transitions and transitionless interactions
S. Longhi, G. Della Valle
The ordinary time-dependent perturbation theory of quantum mechanics, that describes the interaction of a stationary system with a time-dependent perturbation, predicts that the tr…
