Systematic Derivation of Order Parameters through Reduced Density Matrices
Shunsuke Furukawa, Gregoire Misguich, Masaki Oshikawa
A systematic method for determining order parameters for quantum many-body systems on lattices is developed by utilizing reduced density matrices. This method allows one to extract…
Frustrated Quantum Magnets
Claire Lhuillier
A description of different phases of two dimensional magnetic insulators is given. The first chapters are devoted to the understanding of the symmetry breaking mechanism in the sem…
Interacting classical dimers on the square lattice
Fabien Alet, Jesper Lykke Jacobsen, Gregoire Misguich +3
We study a model of close-packed dimers on the square lattice with a nearest neighbor interaction between parallel dimers. This model corresponds to the classical limit of quantum…
