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…
Magnetization plateaus of an easy-axis Kagomé antiferromagnet with extended interactions
X. Plat, F. Alet, S. Capponi +1
We investigate the properties in finite magnetic field of an extended anisotropic XXZ spin-1/2 model on the Kagome lattice, originally introduced by Balents, Fisher, and Girvin [Ph…
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…
Improving entanglement and thermodynamic Rényi entropy measurements in quantum Monte Carlo
David J. Luitz, Xavier Plat, Nicolas Laflorencie +1
We present a method for improving measurements of the entanglement Rényi entropies in quantum Monte Carlo simulations by relating them with measurements of participation Rényi entr…
