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…
