A Hybrid Anyon-Otto thermal machine
Mohit Lal Bera, Joyce Kwan, Armando Pérez +6
We propose a four-stroke quantum thermal machine based on the 1D anyon Hubbard model, which is capable of extracting the excess energy arising from anyon exclusion statistics at lo…
Telling different unravelings apart via nonlinear quantum-trajectory averages
Eloy Piñol, Th. K. Mavrogordatos, Dustin Keys +7
The Gorini-Kossakowski-Sudarshan-Lindblad master equation (ME) governs the density matrix of open quantum systems (OQSs). When an OQS is subjected to weak continuous measurement, i…
Reducing the number of qubits in quantum simulations of one dimensional many-body Hamiltonians
Somayeh Mehrabankar, Miguel Ángel García-March, Carmen G. Almudéver +1
We investigate the Ising and Heisenberg models using the Block Renormalization Group Method (BRGM), focusing on its behavior across different system sizes. The BRGM reduces the num…
Preface: Characterisation of Physical Processes from Anomalous Diffusion Data
Carlo Manzo, Gorka Muñoz-Gil, Giovanni Volpe +3
Preface to the special issue "Characterisation of Physical Processes from Anomalous Diffusion Data" associated with the Anomalous Diffusion Challenge ( https://andi-challenge.org )…
A method for the dynamics of vortices in a Bose-Einstein condensate: analytical equations of the trajectories of phase singularities
S. de María-García, A. Ferrando, J. A. Conejero +2
We present a method to study the dynamics of a quasi-two dimensional Bose-Einstein condensate which contains initially many vortices at arbitrary locations. We present first the an…
Haake-Lewenstein-Wilkens approach to spin-glasses revisited
Maciej Lewenstein, David Cirauqui, Miguel Angel Garcia-March +5
We revisit the Haake-Lewenstein-Wilkens (HLW) approach to Edwards-Anderson (EA) model of Ising spin glass [Phys. Rev. Lett. 55, 2606 (1985)]. This approach consists in evaluation a…
Sub-nK thermometry of an interacting -dimensional homogeneous Bose gas
Muhammad Miskeen Khan, Mohammad Mehboudi, Hugo Tercas +2
We propose experimentally feasible means for non-destructive thermometry of homogeneous Bose Einstein condensates in different spatial dimensions (). Our impurity ba…
Heat current control in trapped BEC
Christos Charalambous, Miguel-Angel Garcia-March, Mohammad Mehboudi +1
We investigate the heat transport and the control of heat current among two spatially separated trapped Bose-Einstein Condensates (BEC), each of them at a different temperature. To…
Analytical solution for multisingular vortex Gaussian beams: The mathematical theory of scattering modes
A. Ferrando, M. A. Garcia-March
We present a novel procedure to solve the Schrödinger equation, which in optics is the paraxial wave equation, with an initial multisingular vortex Gaussian beam. This initial cond…
Entanglement of an Impurity in a Few-Body One-Dimensional Ideal Bose System
M. A. García-March, A. S. Dehkharghani, N. T. Zinner
We study the correlation between an impurity and a small ensemble of bosonic particles in one dimension. Our study analyzes the one-body density matrix and calculates the correspon…
Mesoscopic superpositions of Tonks-Girardeau states and the Bose-Fermi mapping
M. A. García-March, A. V. Yuste-Roca, B. Juliá-Díaz +1
We study a one dimensional gas of repulsively interacting ultracold bosons trapped in a double-well potential as the atom-atom interactions are tuned from zero to infinity. We conc…
Distinguishability, degeneracy and correlations in three harmonically trapped bosons in one-dimension
M. A. García-March, B. Juliá-Díaz, G. E. Astrakharchik +2
We study a system of two bosons of one species and a third boson of a second species in a one-dimensional parabolic trap at zero temperature. We assume contact repulsive inter- and…
Josephson physics of spin-orbit coupled elongated Bose-Einstein condensates
M. A. Garcia-March, G. Mazzarella, L. Dell'Anna +3
We consider an ultracold bosonic binary mixture confined in a one-dimensional double-well trap. The two bosonic components are assumed to be two hyperfine internal states of the sa…
Tunneling, self-trapping and manipulation of higher modes of a BEC in a double well
J. Gillet, M. A. Garcia-March, Th. Busch +1
We consider an atomic Bose-Einstein condensate trapped in a symmetric one-dimensional double well potential in the four-mode approximation and show that the semiclassical dynamics…
Sharp crossover from composite fermionization to phase separation in mesoscopic mixtures of ultracold bosons
M. A. Garcia-March, B. Julia-Diaz, G. E. Astrakharchik +3
We show that a two-component mixture of a few repulsively interacting ultracold atoms in a one-dimensional trap possesses very different quantum regimes and that the crossover betw…
Symmetry breaking and singularity structure in Bose-Einstein condensates
K. A. Commeford, M. A. Garcia-March, A. Ferrando +1
We determine the trajectories of vortex singularities that arise after a single vortex is broken by a discretely symmetric impulse in the context of Bose-Einstein condensates in a…
Vortex macroscopic superpositions in ultracold bosons in a double-well potential
M. A. Garcia-March, Lincoln D. Carr
We study macroscopic superpositions in the orbital rather than the spatial degrees of freedom, in a three-dimensional double-well system. We show that the ensuing dynamics of i…
