Abstract: ABSTRACT The ordering in assemblies of rigid-body rectangles is investigated statistical-mechanically, and the four kinds of liquid crystalline phases that appear as well as the transitions between some of the pairs of these phases are… read more here.

Abstract: In this paper, we study the asymptotic behavior of solutions of an integral equation of the Allen–Cahn type in Rn u(x)=l⃗+C*∫Rnu(y)(1−|u(y)|2)|1−|u(y)|2|p−2|x−y|n−αdy , when |x| → ∞. Here u:Rn→Rk is uniformly continuous, and k ⩾ 1,… read more here.

DOI: 10.1103/physrevb.103.064202
Abstract: Cycloidal spin orders are common in multiferroics. One of the prototypical examples is BiFeO3 (BFO) which shows a large polarization and a cycloidal antiferromagnetic order at room temperature. Here we employ Landau theory and phase-field… read more here.
