Understanding Quantum Imaginary Time Evolution and its Variational form
Andreu Anglés-Castillo, Luca Ion, Tanmoy Pandit +3
Many computationally hard problems can be encoded in quantum Hamiltonians. The solution to these problems is given by the ground states of these Hamiltonians. A state-of-the-art al…
Objective comparison of methods to decode anomalous diffusion
Gorka Muñoz-Gil, Giovanni Volpe, Miguel Angel Garcia-March +31
Deviations from Brownian motion leading to anomalous diffusion are found in transport dynamics from quantum physics to life sciences. The characterization of anomalous diffusion fr…
AnDi: The Anomalous Diffusion Challenge
Gorka Muñoz-Gil, Giovanni Volpe, Miguel Angel Garcia-March +3
The deviation from pure Brownian motion generally referred to as anomalous diffusion has received large attention in the scientific literature to describe many physical scenarios.…
Transient subdiffusion from an Ising environment
G. Muñoz-Gil, C. Charalambous, M. A. García-March +4
We introduce a model, in which a particle performs a continuous time random walk (CTRW) coupled to an environment with Ising dynamics. The particle shows locally varying diffusivit…
Nonequilibrium quantum dynamics of partial symmetry breaking for ultracold bosons in an optical lattice ring trap
Xinxin Zhao, Marie A. McLain, J. Vijande +3
A vortex in a Bose-Einstein condensate on a ring undergoes quantum dynamics in response to a quantum quench in terms of partial symmetry breaking from a uniform lattice to a biperi…
Nonergodic subdiffusion from transient interactions with heterogeneous partners
C. Charalambous, G. Muñoz-Gil, A. Celi +4
Spatiotemporal disorder has been recently associated to the occurrence of anomalous nonergodic diffusion of molecular components in biological systems, but the underlying microscop…
Quantum correlations and spatial localization in one-dimensional ultracold bosonic mixtures
M. A. García-March, B. Juliá-Díaz, G. E. Astrakharchik +3
We present the complete phase diagram for one-dimensional binary mixtures of bosonic ultracold atomic gases in a harmonic trap. We obtain exact results with direct numerical diagon…
Angular Pseudomomentum Theory for the Generalized Nonlinear Schrödinger Equation in Discrete Rotational Symmetry Media
M. -Á. García-March, A. Ferrando, M. Zacarés +2
We develop a complete mathematical theory for the symmetrical solutions of the generalized nonlinear Schrödinger equation based on the new concept of angular pseudomomentum. We con…
Dynamical Realization of Macroscopic Superposition States of Cold Bosons in a Tilted Double Well
Lincoln D. Carr, D. R. Dounas-Frazer, Miguel-Ángel García-March
We present exact expressions for the quantum sloshing of Bose-Einstein condensates in a tilted two-well potential. Tunneling is suppressed by a small potential difference between w…
