Hamiltonian truncation tensor networks for quantum field theories
Philipp Schmoll, Jan Naumann, Alexander Nietner +2
Understanding the equilibrium properties and out of equilibrium dynamics of quantum field theories are key aspects of fundamental problems in theoretical particle physics and cosmo…
A unified diagrammatic approach to topological fixed point models
A. Bauer, J. Eisert, C. Wille
We introduce a systematic mathematical language for describing fixed point models and apply it to the study to topological phases of matter. The framework is reminiscent of state-s…
Quantum time crystals with programmable disorder in higher dimensions
A. Kshetrimayum, M. Goihl, D. M. Kennes +1
We present fresh evidence for the presence of discrete quantum time crystals in two spatial dimensions. Discrete time crystals are intricate quantum systems that break discrete tim…
Efficient variational contraction of two-dimensional tensor networks with a non-trivial unit cell
A. Nietner, B. Vanhecke, F. Verstraete +2
Tensor network states provide an efficient class of states that faithfully capture strongly correlated quantum models and systems in classical statistical mechanics. While tensor n…
A tensor network annealing algorithm for two-dimensional thermal states
A. Kshetrimayum, M. Rizzi, J. Eisert +1
Tensor network methods have become a powerful class of tools to capture strongly correlated matter, but methods to capture the experimentally ubiquitous family of models at finite…
Fermionic topological quantum states as tensor networks
C. Wille, O. Buerschaper, J. Eisert
Tensor network states, and in particular projected entangled pair states, play an important role in the description of strongly correlated quantum lattice systems. They do not only…
