Shannon and entanglement entropies of one- and two-dimensional critical wave functions
TL;DR: In this article, the authors studied the Shannon entropy of the probability distribution resulting from the ground-state wave function of a one-dimensional quantum model and showed that it is composed of an extensive part proportional to the length of the system and a subleading universal constant.

Spin-liquid phase of the multiple-spin exchange Hamiltonian on the triangular lattice
TL;DR: In this paper, an exact diagonalization study of the spin-liquid phase of the multiple-spin exchange model on a triangular lattice was performed, and it was shown that the system is probably not a chiral spin liquid.

Spin Liquid in the Multiple-Spin Exchange Model on the Triangular Lattice: 3 He on Graphite
TL;DR: In this article, the authors investigated the phase diagram of the MSE model on the triangular lattice and found a transition separating a ferromagnetic phase from a nonmagnetic gapped spin liquid phase.

Lattice symmetries and regular magnetic orders in classical frustrated antiferromagnets
TL;DR: In this article, a family of variational spin configurations, called regular magnetic orders (RMOs), are introduced, which respect all the lattice symmetries modulo global O(3) spin transformations (rotations and/or spin flips).

TL;DR: It is shown that this model of close-packed dimers on the square lattice with a nearest neighbor interaction between parallel dimers undergoes a Kosterlitz-Thouless transition separating a low temperature ordered phase where dimers are aligned in columns from a high temperature critical phase with continuously varying exponents.
