Two-dimensional - clock model: Enhanced symmetries, emergent orders, and Landau-incompatible transitions
Vishnu Pulloor Kuttanikkad, Abhishodh Prakash, Rajesh Narayanan +1
We present a comprehensive study on the frustrated - classical -state clock model with even on a two-dimensional square lattice, revealing a rich ensemble of pha…
Phase diagram of Rydberg-dressed atoms on two-leg triangular ladders
Pierre Fromholz, Mikheil Tsitsishvili, Matteo Votto +3
Dressed Rydberg atoms in optical lattices are a promising platform for the quantum simulation of intriguing phenomena emerging in strongly interacting systems. Relevant to such a s…
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…
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…
Coexistence of localized and extended phases: Many-body localization in a harmonic trap
Titas Chanda, Ruixiao Yao, Jakub Zakrzewski
We show that the presence of a harmonic trap may in itself lead to many-body localization for cold atoms confined in that trap in a quasi-one-dimensional geometry. Specifically, th…
Confinement and lack of thermalization after quenches in the bosonic Schwinger model
Titas Chanda, Jakub Zakrzewski, Maciej Lewenstein +1
We excite the vacuum of a relativistic theory of bosons coupled to a gauge field in 1+1 dimensions (bosonic Schwinger model) out of equilibrium by creating a spatially separ…
Time dynamics with matrix product states: Many-body localization transition of large systems revisited
Titas Chanda, Piotr Sierant, Jakub Zakrzewski
We compare accuracy of two prime time evolution algorithms involving Matrix Product States - tDMRG (time-dependent density matrix renormalization group) and TDVP (time-dependent va…
