Phase-locking dynamics of heterogeneous oscillator arrays
Stefano Lepri, Arkady Pikovsky
We consider an array of nearest-neighbor coupled nonlinear autonomous oscillators with quenched random frequencies and purely conservative coupling. We show that global phase-locke…
Nonlocality-induced surface localization in Bose-Einstein condensates of light
Marcello Calvanese Strinati, Frank Vewinger, Claudio Conti
The ability to create and manipulate strongly correlated quantum many-body states is of central importance to the study of collective phenomena in several condensed-matter systems.…
Hydrodynamics and transport in the long-range-interacting chain
Stefano Iubini, Stefano Lepri, Stefano Ruffo
We present a simulation study of the one-dimensional lattice theory with long-range interactions decaying as an inverse power of the intersite distance , $σ>0…
Design of a novel compact neutron collimator
Roberto Bedogni, Marco Costa, Elisabetta Durisi +7
In this work the concept of a novel slow neutron collimator and the way to operate it are presented. The idea is based on the possibility to decouple the device field-of-view from…
Emergent spatial patterns of coexistence in species-rich plant communities
Pablo Villegas, Tommaso Gili, Guido Caldarelli
Statistical Physics has proved essential to analyze multi-agent environments. Motivated by the empirical observation of various non-equilibrium features in Barro Colorado and other…
Computation of microcanonical entropy at fixed magnetization without direct counting
Alessandro Campa, Giacomo Gori, Vahan Hovhannisyan +2
We discuss a method to compute the microcanonical entropy at fixed magnetization without direct counting. Our approach is based on the evaluation of a saddle-point leading to an op…
