A thermally and perturbatively stable classical spin model in two dimensions
Shankar Balasubramanian, Margarita Davydova, Ting-Chun Lin +1
We show that the 2D classical spin model constructed in arXiv:2605.10943 hosts many metastable states at non-zero temperature which are stable to arbitrary Hamiltonian perturbation…
Disentangling the Toric Code
Lei Gioia, Salvatore D. Pace, Ruben Verresen +2
Commuting-projector Hamiltonians with integer spectrum such as the 1+1d Ising ferromagnet and the 2+1d toric code may be regarded as the generators of non-on-site symmetries…
Quantum cellular automata and invertible phases of matter
Corey Jones, Nikita Sopenko, Ryan Thorngren
We introduce and study (fermionic and bosonic) invertible quasi-local algebras over uniformly locally finite metric spaces with infinite-dimensional local von Neumann algebras.…
Correlation versus Causation in Quantum Criticality
Conrad Wichmann, Ryan Thorngren, Ruben Verresen
Correlation functions reveal scaling dimensions through spatial decay. We instead consider static susceptibility, the change in $\langle O_1(x) \ran…
Perturbatively Stable Self-Correcting Classical Memory from Gauge Averaging
Ryan Thorngren
We show that the self-correcting memory in 3d Wegner gauge theory is stable to arbitrary small enough perturbations of the Hamiltonian. Our proof relies on a new method we dub ``ga…
Translation symmetry-enforced long-range entanglement in mixed states
Ryan Thorngren, Lei Gioia, Carolyn Zhang
We show by a counting argument that even though translation symmetry admits symmetric short-range entangled (SRE) eigenstates, there are not enough such SRE eigenstates to span the…
