Borophane as substrate for adsorption of He-4: A journey across dimensionality
Stefania De Palo, Saverio Moroni, Francesco Ancilotto +2
In search of substrates for adsorption of He atoms allowing for novel quantum phases in restricted geometry we study the case of borophane. We focus on two allotropes of borophane,…
Controlling quantum vortex dynamics and vortex-antivortex annihilation in Bose-Einstein condensates with optical lattices
Francesco Ancilotto, Luciano Reatto
Superfluids with strong spatial modulation can be experimentally produced in the area of cold atoms under the influence of optical lattices. Here we address Rb bosons at T=0…
Excitation spectrum in two-dimensional superfluid 4He
F. Arrigoni, E. Vitali, D. E. Galli +1
In this work we perform an ab-initio study of an ideal two-dimensional sample of 4He atoms, a model for 4He films adsorbed on several kinds of substrates. Starting from a realistic…
Ab-initio low-energy dynamics of superfluid and solid 4He
E. Vitali, M. Rossi, L. Reatto +1
We have extracted information about real time dynamics of 4He systems from noisy imaginary time correlation functions f(tau) computed via Quantum Monte Carlo (QMC): production and…
Microscopic studies of solid 4He with Path Integral Projector Monte Carlo
M. Rossi, R. Rota, E. Vitali +2
We have investigated the ground state properties of solid He with the Shadow Path Integral Ground State method. This exact T=0 K projector method allows to describes quantum so…
