Berry phases, current lattices, and suppression of phase transitions in a lattice gauge theory of quantum antiferromagnets
Troels Arnfred Bojesen, Asle Sudbø
We consider a lattice model of two complex scalar matter fields under a CP1 constraint $\abs{z_1}^2+\abs{z_2}^2=1$, minimally coupled to a compact gauge field, with…
Time reversal symmetry breakdown in normal and superconducting states in frustrated three-band systems
Troels Bojesen, Egor Babaev, Asle Sudbø
We discuss the phase diagram and phase transitions in $U(1)\times \groupZ{2}$ three-band superconductors with broken time reversal symmetry. We find that beyond mean field approxim…
Multihistogram Reweighting for Nonequilibrium Markov Processes Using Sequential Importance Sampling Methods
Troels Arnfred Bojesen
We present a multihistogram reweighting technique for nonequilibrium Markov Chains with discrete energies. The method generalizes the single histogram method of Yin et al. [Phys. R…
Phase structure and phase transitions in a three dimensional SU(2) superconductor
Egil V. Herland, Troels A. Bojesen, Egor Babaev +1
We study the three dimensional SU(2)-symmetric noncompact CP1 model, with two charged matter fields coupled minimally to a noncompact Abelian gauge-field. The phase diagram and the…
