Roton excitation in overpressurized superfluid He-4
Youssef Kora, Massimo Boninsegni
We carry out a theoretical investigation of overpressurized superfluid phases of He-4 by means of quantum Monte Carlo (QMC) simulations. As a function of density, we study structur…
Tuning the quantumness of simple Bose systems: A universal phase diagram
Youssef Kora, Massimo Boninsegni, Dam Thanh Son +1
We present a comprehensive theoretical study of the phase diagram of a system of many Bose particles interacting with a two-body central potential of the so-called Lennard-Jones fo…
Dipolar bosons in one dimension: the case of longitudinal dipole alignment
Youssef Kora, Massimo Boninsegni
We study by quantum Monte Carlo simulations the low-temperature phase diagram of dipolar bosons confined to one dimension, with dipole moments aligned along the direction of partic…
Patterned Supersolids in Dipolar Bose Systems
Youssef Kora, Massimo Boninsegni
We study by means of first principle Quantum Monte Carlo simulations the ground state phase diagram of a system of dipolar bosons with aligned dipole moments, and with the inclusio…
Dynamic structure factor of superfluid He-4 from Quantum Monte Carlo: Maximum Entropy revisited
Youssef Kora, Massimo Boninsegni
We use the Maximum Entropy Method (MaxEnt) to estimate the dynamic structure factor of superfluid He-4 at T=1 K, by inverting imaginary-time density correlation functions computed…
