Experimental Observation of Dynamical Phase Transitions in a Dephased Photonic Quantum Walk
Xiaojian Huang, Lei Xiao, Bingzi Huo +3
Dynamical phase transitions in open quantum systems govern how non-equilibrium states relax toward a stationary state. We study these transitions experimentally using a discrete-ti…
Dark-state photonic entanglement filters
Stefano Longhi
Preserving entanglement in the presence of decoherence remains a major challenge for quantum technologies. Recent proposals [M.A. Selim et al., Science 387, 1424 (2025)] have emplo…
Virtual Atom-Photon Bound States and Spontaneous Emission Control
Stefano Longhi
In waveguide quantum electrodynamics systems, atomic radiation emission is shaped by the photonic environment and collective atom interactions, offering promising applications in q…
Laser Mpemba effect
Stefano Longhi
This work explores the emergence of Mpemba-like effects within the quantum theory of lasers. By examining the temporal dynamics of photon number statistics in a single-mode laser a…
Subdiffusive dynamics in photonic random walks probed with classical light
Stefano Longhi
The random walk of photons in a tight-binding lattice is known to exhibit diffusive motion similar to classical random walks under decoherence, clearly illustrating the quantum-to-…
Dephasing-induced mobility edges in quasicrystals
Stefano Longhi
Mobility edges (ME), separating Anderson-localized states from extended states, are known to arise in the single-particle energy spectrum of certain one-dimensional lattices with a…
