Constraint-free wavelength conversion supported by giant optical refraction in a 3D perovskite supercrystal
Ludovica Falsi, Luca Tartara, Fabrizio Di Mei +8
Nonlinear response in a material increases with its index of refraction as . Commonly, 1 so that diffraction, dispersion, and chromatic walk-off limit nonlinear scatt…
Dynamics of a diathermal versus an adiabatic piston in an ideal gas: Langevin's and phase-space approaches
Bruno Crosignani, Paolo Di Porto, Claudio Conti
We present a comparison between the random motion of an adiabatic and a diathermal piston sliding in a perfect gas. In particular, their dynamical behaviour, if investigated by mea…
Perfect Optical Solitons: Spatial Kerr Solitons as Exact Solutions of Maxwell's Equations
Alessandro Ciattoni, Bruno Crosignani, Paolo Di Porto +1
We prove that spatial Kerr solitons, usually obtained in the frame of nonlinear Schroedinger equation valid in the paraxial approximation, can be found in a generalized form as exa…
Callen's Adiabatic Piston and the Limits of the Second Law of Thermodynamics
Bruno Crosignani, Paolo Di Porto, Claudio Conti
The limits of the Second Law of Thermodynamics, which reigns undisputed in the macroscopic world, are investigated at the mesoscopic level, corresponding to spatial dimensions of a…
Feeding upon negative entropy in a thermal-equilibrium environment
B. Crosignani, P. Di Porto, C. Conti
The validity of the Second Law of thermodynamics, indisputable in the macroscopic world, is challenged at the mesoscopic level: a mesoscopic isolated system, possessing spatial dim…
