We study the effect of anisotropy on phase transitions in graphene. work with an low energy effective field theory which is strongly coupled, and solve a coupled set Schwinger-Dyson equations. show that to reduce critical coupling.

A bstract central object in any axionic theory is its periodic potential, which typically generated by instantons. The goal of this paper to understand what physically happens the when we lose control potential’s instanton expansion. We argue, using Yang-Lee phase transitions, that breaks down classic sense: states become light. However, these are not necessarily light for all values axion and ...

Abstract We establish a surface order large deviation estimate for the magnetisation of low temperature $$\phi ^4_3$$ ϕ 3 4 . As byproduct, we obtain decay spectral gap its Glauber dynamics given by singular stochastic PDE. Our main technical cont...

This paper presents the results of model calculations structure Cu-Te system at low temperatures, as well a study and phase transitions synthesized non-stoichiometric compounds copper tellurides. For first time, using USPEX evolutionary algorithm, computer search for stable phases tellurides Cu n Te m (n,m = 1÷10) were carried out. At temperature T 0 K pressure p 1 atm. As structures, compositi...
