Tensor Network Simulation of compact one-dimensional lattice Quantum Chromodynamics at finite density
Pietro Silvi, Yannick Sauer, Ferdinand Tschirsich +1
We perform a zero temperature analysis of a non-Abelian lattice gauge model corresponding to an SU(3) Yang Mills theory in 1+1D at low energies. Specifically, we characterize the m…
Dynamical Ginzburg criterion for the quantum-classical crossover of the Kibble-Zurek mechanism
Matthias Gerster, Benedikt Haggenmiller, Ferdinand Tschirsich +2
We introduce a simple criterion for lattice models to predict quantitatively the crossover between the classical and the quantum scaling of the Kibble-Zurek mechanism, as the one o…
Phase Diagram and Conformal String Excitations of Square Ice using Gauge Invariant Matrix Product States
Ferdinand Tschirsich, Simone Montangero, Marcello Dalmonte
We investigate the ground state phase diagram of square ice -- a U(1) lattice gauge theory in two spatial dimensions -- using gauge invariant tensor network techniques. By correlat…
Probabilistic low-rank factorization accelerates tensor network simulations of critical quantum many-body ground states
Lucas Kohn, Ferdinand Tschirsich, Maximilian Keck +3
We provide evidence that randomized low-rank factorization is a powerful tool for the determination of the ground state properties of low-dimensional lattice Hamiltonians through t…
The Tensor Networks Anthology: Simulation techniques for many-body quantum lattice systems
Pietro Silvi, Ferdinand Tschirsich, Matthias Gerster +4
We present a compendium of numerical simulation techniques, based on tensor network methods, aiming to address problems of many-body quantum mechanics on a classical computer. The…
Density-of-states of many-body quantum systems from tensor networks
Fabian Schrodi, Pietro Silvi, Ferdinand Tschirsich +2
We present a technique to compute the microcanonical thermodynamical properties of a manybody quantum system using tensor networks. The Density Of States (DOS), and more general sp…
Finite-density phase diagram of a (1+1)-d non-abelian lattice gauge theory with tensor networks
Pietro Silvi, Enrique Rico, Marcello Dalmonte +2
We investigate the finite-density phase diagram of a non-abelian SU(2) lattice gauge theory in (1+1)-dimensions using tensor network methods. We numerically characterise the phase…
Superfluid density and quasi-long-range order in the one-dimensional disordered Bose-Hubbard model
Matthias Gerster, Matteo Rizzi, Ferdinand Tschirsich +3
We study the equilibrium properties of the one-dimensional disordered Bose-Hubbard model by means of a gauge-adaptive tree tensor network variational method suitable for systems wi…
