Finite-Temperature Transition in the Spin-Dimer Antiferromagnet BaCuSi2O6
Yoshitomo Kamiya, Naoki Kawashima, Cristian D. Batista
We consider a classical XY-like Hamiltonian on a body-centered tetragonal lattice, focusing on the role of interlayer frustration. A three-dimensional (3D) ordered phase is realize…

Crossover Behavior from Decoupled Criticality
Yoshitomo Kamiya, Naoki Kawashima, C. D. Batista
We study the thermodynamic phase transition of a spin Hamiltonian comprising two 3D magnetic sublattices. Each sublattice contains XY spins coupled by the usual bilinear exchange,…
