Non-Hermitian Bloch-Zener phase transition
Stefano Longhi
Bloch-Zener oscillations (BZO), i.e. the interplay between Bloch oscillations and Zener tunneling in two-band lattices under an external dc force, are ubiquitous in different areas…
Non-Hermitian invisibility in tight-binding lattices
Stefano Longhi, Ermanno Pinotti
A flexible control of wave scattering in complex media is of relevance in different areas of classical and quantum physics. Recently, a great interest has been devoted to scatterin…
Super-phenomena in arbitrary quantum observables
Andrew N. Jordan, Yakir Aharonov, Daniele C. Struppa +6
Superoscillations occur when a globally band-limited function locally oscillates faster than its highest Fourier coefficient. We generalize this effect to arbitrary quantum mechani…
Quantum matching pursuit: A quantum algorithm for sparse representations
Armando Bellante, Stefano Zanero
Representing signals with sparse vectors has a wide range of applications that range from image and video coding to shape representation and health monitoring. In many applications…
Invisible non-Hermitian potentials in discrete-time photonic quantum walks
Stefano Longhi
Discrete-time photonic quantum walks on a synthetic lattice, where both spatial and temporal evolution of light is discretized, have provided recently a fascinating platform for th…
Non-Hermitian Hartman effect
Stefano Longhi
The Hartman effect refers to the rather paradoxical result that the time spent by a quantum mechanical particle or a photon to tunnel through an opaque potential barrier becomes in…
Non-Hermitian skin effect and self-acceleration
Stefano Longhi
Non-Hermitian systems exhibit nontrivial band topology and a strong sensitivity of the energy spectrum on the boundary conditions. Remarkably, a macroscopic number of bulk states g…
Non-Hermitian topological mobility edges and transport in photonic quantum walks
Stefano Longhi
In non-Hermitian quasicrystals, mobility edges (ME) separating localized and extended states in complex energy plane can arise as a result of non-Hermitian terms in the Hamiltonian…
Self-healing of non-Hermitian topological skin modes
Stefano Longhi
A unique feature of non-Hermitian (NH) systems is the NH skin effect, i.e. the edge localization of an extensive number of bulk-band eigenstates in a lattice with open or semi-infi…
The Generalized Fibonacci Oscillator as an Open Quantum System
Franco Fagnola, Chul Ki Ko, Hyun Jae Yoo
We consider an open quantum system with Hamiltonian whose spectrum is given by a generalized Fibonacci sequence weakly coupled to a Boson reservoir in equilibrium at inverse…
Quantifying n-photon indistinguishability with a cyclic integrated interferometer
Mathias Pont, Riccardo Albiero, Sarah E. Thomas +14
We report on a universal method to measure the genuine indistinguishability of n-photons - a crucial parameter that determines the accuracy of optical quantum computing. Our approa…
