Algebraic Fusion in a (2+1)-dimensional Lattice Model with Generalized Symmetries
Chinmay Giridhar, Philipp Vojta, Zohar Nussinov +2
The notion of quantum symmetry has recently been extended to include reduced-dimensional transformations and algebraic structures beyond groups. Such generalized symmetries lead to…

Generalized Wigner theorem for non-invertible symmetries
Gerardo Ortiz, Chinmay Giridhar, Philipp Vojta +2
We establish the conditions under which a conservation law associated with a non-invertible operator may be realized as a symmetry in quantum physics. As established by Wigner, all…

Topological Orders Beyond Topological Quantum Field Theories
P. Vojta, G. Ortiz, Z. Nussinov
Systems displaying quantum topological order feature robust characteristics that are very attractive to quantum computing schemes. Topological quantum field theories have proven to…
