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…
A no-go result for implementing chiral symmetries by locality-preserving unitaries in a 3 dimensional Hamiltonian lattice model of fermions
Lukasz Fidkowski, Cenke Xu
We argue that the chiral symmetry of a Weyl fermion cannot be implemented by a shallow depth quantum circuit operation in a fermionic lattice Hamiltonian model with finite…
Entanglement transitions with free fermions
Joseph Merritt, Lukasz Fidkowski
We use Majorana operators to study entanglement dynamics under random free fermion unitary evolution and projective measurements in one dimension. For certain choices of unitary ev…
