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…
Boundary-Driven Exceptional Points in Photonic Waveguide Lattices
Stefano Longhi
We predict and analyze boundary-driven exceptional points in semi-infinite Hermitian photonic waveguide lattices with a side-coupled defect. The exceptional points arise from coher…
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…
Lifshitz tail states in non-Hermitian disordered photonic lattices
Stefano Longhi
In lattices with uncorrelated on-site potential disorder, Anderson localization near the band edges can exhibit anomalously weak localization in the form of Lifshitz tail states. T…
Resonances, mobility edges and gap-protected Anderson localization in generalized disordered mosaic lattices
Stefano Longhi
Mosaic lattice models have been recently introduced as a special class of disordered systems displaying resonance energies, multiple mobility edges and anomalous transport properti…
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-…
Photonic Mpemba effect
Stefano Longhi
The Mpemba effect is the counterintuitive phenomenon in statistical physics for which a far-from-equilibrium state can relax toward equilibrium faster than a state closer to equili…
Non-Hermitian dynamical topological winding in photonic mesh lattices
Stefano Longhi
Topological winding in non-Hermitian systems are generally associated to the Bloch band properties of lattice Hamiltonians. However, in certain non-Hermitian models topological win…
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…
Photonic random walks with traps
Stefano Longhi
Random walks behave very differently for classical and quantum particles. Here we unveil a ubiquitous distinctive behavior of random walks of a photon in a one-dimensional lattice…
Robust Anderson transition in non-Hermitian photonic quasicrystals
Stefano Longhi
Anderson localization, i.e. the suppression of diffusion in lattices with random or incommensurate disorder, is a fragile interference phenomenon which is spoiled out in the presen…
Incoherent non-Hermitian skin effect in photonic quantum walks
Stefano Longhi
The non-Hermitian skin effect describes the concentration of an extensive number of eigenstates near the boundaries of certain dissipative systems. This phenomenon has raised a hug…
Self acceleration from spectral geometry in dissipative quantum-walk dynamics
Peng Xue, Quan Lin, Kunkun Wang +3
Dynamic behaviors of a physical system often originate from its spectral properties. In open systems, where the effective non-Hermitian description enables a wealth of spectral str…
