Accurate Helium-Benzene Potential: from CCSD(T) to Gaussian Process Regression
Shahzad Akram, Sutirtha Paul, Collin Kovacs +3
The accurate modeling of non-covalent interactions between helium and graphitic materials is important for understanding quantum phenomena in reduced dimensions, with the helium-be…
Berezinskii-Kosterlitz-Thouless Renormalization Group Flow at a Quantum Phase Transition
Matthias Thamm, Harini Radhakrishnan, Hatem Barghathi +4
We present a controlled numerical study of the Berezinskii-Kosterlitz-Thouless (BKT) transition in the one-dimensional Bose-Hubbard model at unit filling, providing evidence of the…
Two-Dimensional Bose-Hubbard Model for Helium on Graphene
Jiangyong Yu, Ethan Lauricella, Mohamed Elsayed +9
An exciting development in the field of correlated systems is the possibility of realizing two-dimensional (2D) phases of quantum matter. For a systems of bosons, an example of str…
Theory of Non-Interacting Fermions and Bosons in the Canonical Ensemble
Hatem Barghathi, Jiangyong Yu, Adrian Del Maestro
We present a self-contained theory for the exact calculation of particle number counting statistics of non-interacting indistinguishable particles in the canonical ensemble. This g…
Dimensional Reduction of Helium-4 Inside Argon Plated MCM-41 Nanopores
Nathan Nichols, Timothy R. Prisk, Garfield Warren +2
The angstrom-scale coherence length describing the superfluid wavefunction of helium-4 at low temperatures has prevented its preparation in a truly one-dimensional geometry. Mesopo…
Operationally accessible entanglement of one dimensional spinless fermions
Hatem Barghathi, Emanuel Casiano-Diaz, Adrian Del Maestro
For indistinguishable itinerant particles subject to a superselection rule fixing their total number, a portion of the entanglement entropy under a spatial bipartition of the groun…
Helium-4 Luttinger liquids in nanopores
Adrian Del Maestro, Massimo Boninsegni, Ian Affleck
We study the low temperature properties of a helium-4 fluid confined in nanopores, using large-scale Quantum Monte Carlo simulations with realistic He-He and He-pore interactions.…
Infinite randomness fixed point of the superconductor-metal quantum phase transition
Adrian Del Maestro, Bernd Rosenow, Markus Mueller +1
We examine the influence of quenched disorder on the superconductor-metal transition, as described by a theory of overdamped Cooper pairs which repel each other. The self-consisten…
