Thermo-magnonic diode: rectification of energy and magnetization currents
Simone Borlenghi, Stefano Lepri, Lars Bergqvist +1
We investigate the dynamics of two coupled macrospins connected to thermal baths at different temperatures. The system behaves like a diode which allows the propagation of energy a…
Experimental and theoretical investigation of statistical regimes in random laser emission
Emilio Ignesti, Federico Tommasi, Lorenzo Fini +4
We present a theoretical and experimental study aimed at characterizing statistical regimes in a random laser. Both the theoretical simulations and the experimental results show th…
Off-equilibrium Langevin dynamics of the discrete nonlinear Schroedinger chain
S. Iubini, S. Lepri, R. Livi +1
Suitable Langevin thermostats are introduced which are able to control both the temperature and the chemical potential of a one-dimensional lattice of nonlinear Schrödinger oscilla…
Symmetry breaking and restoring wave transmission in diode-antidiode double chains
Stefano Lepri, Boris A. Malomed
We introduce a system of two parallel-coupled discrete nonlinear Schroedinger (DNLS) inhomogeneous chains. Each one favors the unidirectional transmission of incident packets, in t…
