Composite subsystem symmetries and decoration of sub-dimensional excitations
Avi Vadali, Zongyuan Wang, Arpit Dua +2
Flux binding is a mechanism that is well-understood for global symmetries. Given two systems, each with a global symmetry, gauging the composite symmetry instead of individual symm…
Sequential Quantum Circuits as Maps between Gapped Phases
Xie Chen, Arpit Dua, Michael Hermele +4
Finite-depth quantum circuits preserve the long-range entanglement structure in quantum states and map between states within a gapped phase. To map between states of different gapp…
String operators for Cheshire strings in topological phases
Nathanan Tantivasadakarn, Xie Chen
Elementary point charge excitations in 3+1D topological phases can condense along a line and form a descendant excitation called the Cheshire string. Unlike the elementary flux loo…
Renormalization of Ising cage-net model and generalized foliation
Zongyuan Wang, Xiuqi Ma, David T. Stephen +2
A large class of type-I fracton models, including the X-cube model, have been found to be fixed points of the foliated renormalization group (RG). The system size of such foliated…
