Non-Invertible Symmetries Mixing with Witt Non-Trivial Quantum Cellular Automata
Kansei Inamura, Oskar Wojdel, Lukasz Fidkowski +1
Self-dualities and the stacking of symmetry-protected topological (SPT) phases are basic operations on quantum many-body systems. For a one-form symmetry in 3+1d the…
Stabilizer Scars
Jeremy Hartse, Lukasz Fidkowski, Niklas Mueller
Quantum many-body scars are eigenstates in non-integrable isolated quantum systems that defy typical thermalization paradigms, violating the eigenstate thermalization hypothesis an…
A QCA for every SPT
Lukasz Fidkowski, Jeongwan Haah, Matthew B. Hastings
In three dimensions, there is a nontrivial quantum cellular automaton (QCA) which disentangles the three-fermion Walker--Wang model, a model whose action depends on Stiefel--Whitne…
Pumping Chirality in Three Dimensions
Lukasz Fidkowski, Matthew B. Hastings
Using bosonization, which maps fermions coupled to a gauge field to a qubit system, we give a simple form for the non-trivial 3-fermion quantum cellular automaton…
