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…
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…
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…
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…
