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…

Self-organized topological insulator due to cavity-mediated correlated tunneling

Titas Chanda, Rebecca Kraus, Giovanna Morigi +1

Topological materials have potential applications for quantum technologies. Non-interacting topological materials, such as e.g., topological insulators and superconductors, are cla…

Many-body localization transition in large quantum spin chains: The mobility edge

Titas Chanda, Piotr Sierant, Jakub Zakrzewski

Thermalization of random-field Heisenberg spin chain is probed by time evolution of density correlation functions. Studying the impacts of average energies of initial product state…

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…

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…
