Long-range entanglement from measuring symmetry-protected topological phases
Nathanan Tantivasadakarn, Ryan Thorngren, Ashvin Vishwanath +1
A fundamental distinction between many-body quantum states are those with short- and long-range entanglement (SRE and LRE). The latter cannot be created by finite-depth circuits, u…
Building models of topological quantum criticality from pivot Hamiltonians
Nathanan Tantivasadakarn, Ryan Thorngren, Ashvin Vishwanath +1
Progress in understanding symmetry-protected topological (SPT) phases has been greatly aided by our ability to construct lattice models realizing these states. In contrast, a syste…
Pivot Hamiltonians as generators of symmetry and entanglement
Nathanan Tantivasadakarn, Ryan Thorngren, Ashvin Vishwanath +1
It is well-known that symmetry-protected topological (SPT) phases can be obtained from the trivial phase by an entangler, a finite-depth unitary operator . Here, we consider obt…
Exact correlations in topological quantum chains
Nick G. Jones, Ruben Verresen
Although free-fermion systems are considered exactly solvable, they generically do not admit closed expressions for nonlocal quantities such as topological string correlations or e…
Skeleton of Matrix-Product-State-Solvable Models Connecting Topological Phases of Matter
Nick G. Jones, Julian Bibo, Bernhard Jobst +3
Models whose ground states can be written as an exact matrix product state (MPS) provide valuable insights into phases of matter. While MPS-solvable models are typically studied as…
Probing Topological Spin Liquids on a Programmable Quantum Simulator
Giulia Semeghini, Harry Levine, Alexander Keesling +13
Quantum spin liquids, exotic phases of matter with topological order, have been a major focus of explorations in physical science for the past several decades. Such phases feature…
Realising the Symmetry-Protected Haldane Phase in Fermi-Hubbard Ladders
Pimonpan Sompet, Sarah Hirthe, Dominik Bourgund +10
Topology in quantum many-body systems has profoundly changed our understanding of quantum phases of matter. The paradigmatic model that has played an instrumental role in elucidati…
Quotient symmetry protected topological phenomena
Ruben Verresen, Julian Bibo, Frank Pollmann
Topological phenomena are commonly studied in phases of matter which are separated from a trivial phase by an unavoidable quantum phase transition. This can be overly restrictive,…
