Quantum phases of dipolar bosons in one-dimensional optical lattices
Rebecca Kraus, Titas Chanda, Jakub Zakrzewski +1
We theoretically analyze the phase diagram of a quantum gas of bosons that interact via repulsive dipolar interactions. The bosons are tightly confined by an optical lattice in a q…
Terahertz Frequency Domain Sensing for Fast Porosity Measurement of Pharmaceutical Tablets
Anis Moradikouchi, Anders Sparén, Staffan Folestad +2
Porosity is an important property of pharmaceutical tablets since it may affect tablet disintegration, dissolution, and bio-availability. It is, therefore, essential to establish n…
Challenges to observation of many-body localization
Piotr Sierant, Jakub Zakrzewski
We study time dynamics of 1D disordered Heisenberg spin-1/2 chain focusing on a regime of large system sizes and a long time evolution. This regime is relevant for observation of m…
Finite-Size scaling analysis of many-body localization transition in quasi-periodic spin chains
Adith Sai Aramthottil, Titas Chanda, Piotr Sierant +1
We analyze the finite-size scaling of the average gap-ratio and the entanglement entropy across the many-body localization (MBL) transition in one dimensional Heisenberg spin-chain…
On intermediate statistics across many-body localization transition
Bitan De, Piotr Sierant, Jakub Zakrzewski
The level statistics in the transition between delocalized and localized {phases of} many body interacting systems is {considered}. We recall the joint probability distribution for…
Phase diagram of 1+1D Abelian-Higgs model and its critical point
Titas Chanda, Maciej Lewenstein, Jakub Zakrzewski +1
We determine the phase diagram of the Abelian-Higgs model in one spatial dimension and time (1+1D) on a lattice. We identify a line of first order phase transitions separating the…
Cold atoms meet lattice gauge theory
Monika Aidelsburger, Luca Barbiero, Alejandro Bermudez +19
The central idea of this review is to consider quantum field theory models relevant for particle physics and replace the fermionic matter in these models by a bosonic one. This is…
Optical lattice for tripod-like atomic level structure
Piotr Kubala, Jakub Zakrzewski, Mateusz Łącki
Standard optical potentials use off-resonant laser standing wave induced AC-Stark shift. In a recent development [Phys. Rev. Lett. {\bf 117}, 233001 (2016)] a three-level scheme in…
Detecting ergodic bubbles at the crossover to many-body localization using neural networks
Tomasz Szoldra, Piotr Sierant, Korbinian Kottmann +2
The transition between ergodic and many-body localized phases is expected to occur via an avalanche mechanism, in which \emph{ergodic bubbles} that arise due to local fluctuations…
Three-electron correlations in strong laser field ionization: Spin induced effects
Dmitry Efimov, Artur Maksymov, Marcelo Ciapina +3
Strong field processes in the non-relativistic regime are insensitive to the electron spin, i.e. the observables appear to be independent of this electron property. This does not h…
Constraints induced delocalization
Piotr Sierant, Eduardo Gonzalez Lazo, Marcello Dalmonte +2
We study the impact of quenched disorder on the dynamics of locally constrained quantum spin chains, that describe 1D arrays of Rydberg atoms in both frozen (Ising-type) and dresse…
Many-body localization in tilted and harmonic potentials
Ruixiao Yao, Titas Chanda, Jakub Zakrzewski
We discuss nonergodic dynamics of interacting spinless fermions in a tilted optical lattice as modeled by XXZ spin chain in magnetic (or electric) field changing linearly across th…
Strong-field triple ionization of atoms with valence shell
Jakub S. Prauzner-Bechcicki, Dmitry K. Efimov, Michał Mandrysz +1
The interaction of strong pulsed femtosecond laser field with atoms having three equivalent electrons in the outer shell ( configuration, e.g. nitrogen) is studied via numeric…
Nonergodic dynamics in disorder-free potentials
Ruixiao Yao, Titas Chanda, Jakub Zakrzewski
We review the dynamics of interacting particles in disorder-free potentials concentrating on a combination of a harmonic binding with a constant tilt. We show that a simple picture…
