Breaking the Exponential: Decoherence-Driven Power-Law Spontaneous Emission in Waveguide Quantum Electrodynamics
Stefano Longhi
We investigate the spontaneous emission of a two-level system coupled to a photonic waveguide, showing that dynamical dephasing in the photon modes profoundly alters the decay law.…
Quantum Mpemba effect from initial system-reservoir entanglement
Stefano Longhi
The Mpemba effect -- where hot systems cool faster than colder ones -- has intrigued both classical and quantum thermodynamics. As compared to classical systems, quantum systems ad…
Erratic non-Hermitian skin localization
Stefano Longhi
A novel localization phenomenon, termed erratic non-Hermitian skin localization, has been identified in disordered globally-reciprocal non-Hermitian lattices. Unlike conventional n…
Modulational Instability and Dynamical Growth Blockade in the Nonlinear Hatano-Nelson Model
Stefano Longhi
The Hatano-Nelson model is a cornerstone of non-Hermitian physics, describing asymmetric hopping dynamics on a one-dimensional lattice, which gives rise to fascinating phenomena su…
Mpemba effect and super-accelerated thermalization in the damped quantum harmonic oscillator
Stefano Longhi
The behavior of systems far from equilibrium is often complex and unpredictable, challenging and sometimes overturning the physical intuition derived from equilibrium scenarios. On…
