Metastable state en route to traveling-wave synchronization state

2018-02-20T10:00:00+00:00

Author(s): Jinha Park and B. Kahng

The Kuramoto model with mixed signs of couplings is known to produce a traveling-wave synchronized state. Here, we consider an abrupt synchronization transition from the incoherent state to the traveling-wave state through a long-lasting metastable state with large fluctuations. Our explanation of t...

Generalized thermodynamics of phase equilibria in scalar active matter

2018-02-20T10:00:00+00:00

Author(s): Alexandre P. Solon, Joakim Stenhammar, Michael E. Cates, Yariv Kafri, and Julien Tailleur

Motility-induced phase separation (MIPS) arises generically in fluids of self-propelled particles when interactions lead to a kinetic slowdown at high densities. Starting from a continuum description of scalar active matter akin to a generalized Cahn-Hilliard equation, we give a general prescription...

Author(s): Julio A. López-Saldívar, Octavio Castaños, Margarita A. Man'ko, and Vladimir I. Man'ko

The positivity conditions of the relative entropy between two thermal equilibrium states ${\stackrel{̂}{ρ}}_{1}$ and ${\stackrel{̂}{ρ}}_{2}$ are used to obtain upper and lower bounds for the subtraction of their entropies, the Helmholtz potential and the Gibbs potential of the two systems. These lim...

Author(s): Gaole Dai, Jin Shang, and Jiping Huang

Heat can transfer via thermal conduction, thermal radiation, and thermal convection. All the existing theories of transformation thermotics and optics can treat thermal conduction and thermal radiation, respectively. Unfortunately, thermal convection has seldom been touched in transformation theorie...

Achieving the classical Carnot efficiency in a strongly coupled quantum heat engine

Author(s): Y. Y. Xu, B. Chen, and J. Liu

Generally, the efficiency of a heat engine strongly coupled with a heat bath is less than the classical Carnot efficiency. Through a model-independent method, we show that the classical Carnot efficiency is achieved in a strongly coupled quantum heat engine. First, we present the first law of quantu...

Author(s): Qiang Liu and Piet Van Mieghem

Since a real epidemic process is not necessarily Markovian, the epidemic threshold obtained under the Markovian assumption may be not realistic. To understand general non-Markovian epidemic processes on networks, we study the Weibullian susceptible-infected-susceptible (SIS) process in which the inf...

Phase diagram of restricted Boltzmann machines and generalized Hopfield networks with arbitrary priors

2018-02-20T10:00:00+00:00

Author(s): Adriano Barra, Giuseppe Genovese, Peter Sollich, and Daniele Tantari

This paper studies the connection between Hopfield networks and restricted Boltzmann machines, two common tools in the developing area of machine learning. The work focuses on the behavior of models whose variables are either discrete and binary or take on a range of continuous values. The authors find a large degree of robustness in the retrieval capabilities of the models, especially when the number of stored patterns is small.
