Topological aspects of symmetry breaking in triangular-lattice Ising antiferromagnets
Andrew Smerald, Sergey Korshunov, Frederic Mila
Using a specially designed Monte Carlo algorithm with directed loops, we investigate the triangular lattice Ising antiferromagnet with coupling beyond nearest neighbour. We show th…
Physical realization of the generalized fully frustrated XY model in an array of SFS junctions
S. E. Korshunov
We show that a physical realization of the phase diagram proposed by Minnhagen et al. [Phys. Rev. B 78, 184432 (2008)] for so-called generalized fully frustrated XY model on square…
Competing structures in 2D-trapped dipolar gases
Barbara Gränz, Sergey E. Korshunov, Vadim B. Geshkenbein +1
We study a system of dipolar molecules confined in a two-dimensional trap and subject to an optical square lattice. The repulsive long-range dipolar interaction favors an e…
Semiclassical evidence of columnar order in the fully frustrated transverse field Ising model on the square lattice
Tommaso Coletta, Sergey E. Korshunov, Frédéric Mila
We investigate the zero-temperature phase diagram of the fully frustrated transverse field Ising model on the square lattice both in the classical limit and in the presence of quan…
Zero-temperature Monte Carlo study of the non-coplanar phase of the classical bilinear-biquadratic Heisenberg model on the triangular lattice
Sandro Wenzel, Sergey E. Korshunov, Karlo Penc +1
We investigate the ground-state properties of the highly degenerate non-coplanar phase of the classical bilinear-biquadratic Heisenberg model on the triangular lattice with Monte C…
Finite-temperature phase transitions in the quantum fully frustrated Ising models
S. E. Korshunov
The quantum antiferromagnetic spin-1/2 Ising model on a triangular lattice and analogous fully frustrated Ising model on a square lattice with quantum fluctuations induced by the a…
