The generic Mott transition in the sine-Gordon model through an embedded worm algorithm
Oscar Bouverot-Dupuis, Laura Foini, Alberto Rosso
The generic Mott transition in one-dimensional quantum systems can be described by the sine-Gordon model with a tilt via bosonization. Because the configuration space of the sine-G…
Bosonized one-dimensional quantum systems through enhanced event-chain Monte Carlo
Oscar Bouverot-Dupuis, Alberto Rosso, Manon Michel
We design an enhanced Event-Chain Monte Carlo algorithm to study 1D quantum dissipative systems, using their bosonized representation. Expressing the bosonized Hamiltonian as a pat…
Inhomogeneous Evolution of a Dense Ensemble of Optically Pumped Excitons to a Charge Transfer State
Natasha Kirova, Serguei Brazovskii
Phase transformations induced by short optical pulses are mainstream in studies on the dynamics of cooperative electronic states. We present a semi-phenomenological modeling of spa…
Entanglement content of kink excitations
Luca Capizzi, Michele Mazzoni
Quantum one-dimensional systems in their ordered phase admit kinks as elementary excitations above their symmetry-broken vacua. While the scattering properties of the kinks resembl…
Tracking defects of Electronic Crystals by Coherent X-ray Diffraction
David Le Bolloc'h, E. Bellec, N. Kirova +1
In this article, we review different studies based on advanced x-ray diffraction techniques - especially coherent x-ray diffraction - that allowed us to reveal the behaviour of suc…
Laughlin's quasielectron as a non-local composite fermion
Alberto Nardin, Leonardo Mazza
We discuss the link between the quasielectron wavefunctions proposed by Laughlin and by Jain and show both analytically and numerically that Laughlin's quasielectron is a non-local…
