Entanglement spectrum as a marker for phase transitions in the density embedding theory for interacting spinless fermionic models
Xavier Plat, Chisa Hotta
Entanglement related properties work as nice fingerprint of the quantum many-body wave function. However, those of fermionic models are hard to evaluate in standard numerical metho…

Kinetic frustration induced supersolid in the kagome lattice antiferromagnet in a magnetic field
Xavier Plat, Tsutomu Momoi, Chisa Hotta
We examine instabilities of the plateau phases in the spin-1/2 kagome-lattice antiferromagnet in an applied field by means of degenerate perturbation theory, and find some emergent…

Universal logarithmic corrections to entanglement entropies in two dimensions with spontaneously broken continuous symmetries
David J. Luitz, Xavier Plat, Fabien Alet +1
We explore the Rényi entanglement entropies of a one-dimensional (line) subsystem of length embedded in two-dimensional square lattice for quantum spin models whose…
