Comparative study of matrix product state/quantized tensor-train algorithms for solving time-independent partial differential equations
Paula GarcÃa-Molina, Luca Tagliacozzo, Juan José GarcÃa-Ripoll
This work presents a comparative study of new and existing optimization and diagonalization methods for solving time-independent partial differential equations (PDEs) using matrix…

Stability of the symmetry-protected topological phase and Ising transitions in a disordered U(1) quantum link model on a ladder
Mykhailo V. Rakov, Luca Tagliacozzo, Maciej Lewenstein +2
We revisit the U(1) quantum link model in a ladder geometry, finding, by finite-size scaling, that the critical exponent and the central charge are consistent with th…

Gapless deconfined phase in a symmetric Hamiltonian created in a cold-atom setup
Mykhailo V. Rakov, Luca Tagliacozzo, Maciej Lewenstein +2
We investigate a quasi-two-dimensional system consisting of two species of alkali atoms confined in a specific optical lattice potential [Phys. Rev. A 95, 053608 (2017)]. In the lo…
