Classical spin dynamics based on coherent states
H Zhang, CD Batista - Physical Review B, 2021 - APS
We introduce a classical limit of the dynamics of quantum spin systems based on coherent
states of SU (N), where N is the dimension of the local Hilbert space. This approach, which …

Hybridized quadrupolar excitations in the spin-anisotropic frustrated magnet FeI2
Magnetic order is usually associated with well-defined magnon excitations. Exotic magnetic
fluctuations with fractional, topological or multipolar character have been proposed for …

Tensor networks and efficient descriptions of classical data
We investigate the potential of tensor network based machine learning methods to scale to
large image and text data sets. For that, we study how the mutual information between a …

Generalization of group-theoretic coherent states for variational calculations
We introduce families of pure quantum states that are constructed on top of the well-known
Gilmore-Perelomov group-theoretic coherent states. We do this by constructing unitaries as …

Phase diagram of semi-hard-core bosons on a square lattice
VV Konev, YD Panov - Physics of the Solid State, 2021 - Springer
Phase diagrams of charged “semi-hard-core” bosons are studied in the mean field
approximation. An increase in the parameter of local correlations is shown to lead to the …
