Skeleton of isometric Tensor Network States for Abelian String-Net Models
Julian Boesl, Yu-Jie Liu, Frank Pollmann +1
We construct parametrized isometric tensor network states -- referred to as skeletons -- that allow us to explore phases of abelian topological order and can be efficiently impleme…
Simulating Topological Order on Quantum Processors
Adam Gammon-Smith, Michael Knap, Frank Pollmann
It is an ongoing quest to realize topologically ordered quantum states on different platforms including condensed matter systems, quantum simulators and digital quantum processors.…
Anisotropic Spin Ice on a Breathing Pyrochlore Lattice
Gloria Isbrandt, Frank Pollmann, Michael Knap
Spin ice systems represent a prime example of constrained spin systems and exhibit rich low-energy physics. In this study, we explore how introducing a tunable anisotropic spin cou…
Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
Tensor-network study of the roughening transition in a (2 + 1)D lattice gauge theory with matter
Wen-Tao Xu, Michael Knap, Frank Pollmann
Within the confined phase of (2+1)D lattice gauge theories a roughening transition arises between a weakly confined regime with floppy string excitations and a strongly confined re…
Information-theoretic principle of emergent 1-form symmetries
Yu-Jie Liu, Wen-Tao Xu, Frank Pollmann +1
Higher-form symmetries act on sub-dimensional spatial manifolds of a quantum system. They can emerge as an exact symmetry at low energies even when they are explicitly broken at th…
Quantum Phase Transitions between Symmetry-Enriched Fracton Phases
Julian Boesl, Yu-Jie Liu, Wen-Tao Xu +2
Topologically ordered phases exhibit further complexity in the presence of global symmetries: Their anyonic excitations may exhibit different transformation patterns under these sy…
Probing non-equilibrium topological order on a quantum processor
M. Will, T. A. Cochran, E. Rosenberg +6
Out-of-equilibrium phases in many-body systems constitute a new paradigm in quantum matter - they exhibit dynamical properties that may otherwise be forbidden by equilibrium thermo…
