We have calculated the masses of bound states numerically in $ \mathcal{N} $ = 1 supersymmetric Yang-Mills theory with gauge group SU(2). Using the suitably optimise

Convergent series for polynomial lattice models with complex actions

Autor: V. K. Sazonov

Mod.Phys.Lett.A, 2019, 34 (30), pp.1950243. ⟨10.1142/S0217732319502432⟩

Lattice models with complex actions are important for the understanding of matter at finite densities, but not accessible by the standard Monte Carlo techniques due to the sign problem. Here we derive a new approach for avoiding the complex action/si

Report

Diversity of quantum ground states and quantum phase transitions of a spin-1/2 Heisenberg octahedral chain

Autor: Strecka, Jozef, Richter, Johannes, Derzhko, Oleg, Verkholyak, Taras, Karlova, Katarina

Publikováno v: Phys. Rev. B 95, 224415 (2017)

The spin-1/2 Heisenberg octahedral chain with regularly alternating monomeric and square-plaquette sites is investigated using various analytical and numerical methods: variational technique, localized-magnon approach, exact diagonalization (ED) and
