Phase diagram of Rydberg-dressed atoms on two-leg square ladders: Coupling supersymmetric conformal field theories on the lattice
Mikheil Tsitsishvili, Titas Chanda, Matteo Votto +3
We investigate the phase diagram of hard-core bosons in two-leg ladders in the presence of soft-shoulder potentials. We show how the competition between local and non-local terms g…
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…
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…
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…
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…
Non-adiabatic dynamics across a first order quantum phase transition: Quantized bubble nucleation
Aritra Sinha, Titas Chanda, Jacek Dziarmaga
Metastability is a quintessential feature of first order quantum phase transitions, which is lost either by dynamical instability or by nucleating bubbles of a true vacuum through…
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…
