The generalized Gibbs ensemble (GGE), which involves multiple conserved quantities other than the Hamiltonian, has served as the statistical-mechanical description of the long-time behavior for several isolated integrable quantum systems. We argue th

A variety of aspects have been the target of discussion in linguistic literature. Degree achievement verbs are 'murky' in that they cannot be classified as an appropriate type from the perspective of telicity. Japanese DAs are derived from adjectives

We study theoretically the dynamics of composite domain walls (DW) in multiferroic material GdFeO${}_3$ driven by magnetic field $H$. Two antiferromagnetic orders of Fe and Gd spins interact Gd-ion displacement in this system with coupling $c$ at low

This paper presents a method for optimally operating a hybrid system of fuel cell and photovoltaic in household. We apply a stochastic programming in which solar radiation and power demands are considered as random variables to the system. An error b
