Fermi polaron in atom-ion hybrid systems
Renato Pessoa, S. A Vitiello, L. A Peña Ardila
Atom-ion hybrid systems are promising platforms for the quantum simulation of polaron physics in certain quantum materials. Here, we investigate the ionic Fermi polaron, a charged…
Properties of fermionic systems with the Path-integral ground state method
Sebastian Ujevick, V. Zampronio, B. R. de Abreu +1
We investigate strongly correlated many-body systems composed of bosons and fermions with a fully quantum treatment using the path-integral ground state method, PIGS. To account fo…
Finite-range effects in the unitary Fermi polaron
Renato Pessoa, S. A. Vitiello, L. A. Peña Ardila
Quantum Monte Carlo techniques are employed to study the properties of polarons in an ultracold Fermi gas, at and in the unitary regime using both a zero-range model and a…
Properties of the Superfluid in the Disordered Bose-Hubbard Model
Bruno R. de Abreu, Ushnish Ray, Silvio A. Vitiello +1
We investigate the properties of the superfluid phase in the three-dimensional disordered Bose-Hubbard model using Quantum Monte-Carlo simulations. The phase diagram is generated u…
Ground-state properties of unitary bosons: from clusters to matter
J. Carlson, S. Gandolfi, U. van Kolck +1
The properties of cold Bose gases at unitarity have been extensively investigated in the last few years both theoretically and experimentally. In this paper we use a family of inte…
Shadow wave function with a symmetric kernel
V. Zampronio, V. Z. Pedroso, S. A. Vitiello
A shadow wave function with an explicit symmetric kernel is introduced. As a consequence the atoms exchange in the system is enhanced. Basic properties of this class of trial funct…
