Filling constraints on translation invariant dipole conserving systems
Fiona J. Burnell, Sanjay Moudgalya, Abhinav Prem
Systems with conserved dipole moment have drawn considerable interest in light of their realization in recent experiments on tilted optical lattices. An important question for such…
Prethermal stability of eigenstates under high frequency Floquet driving
Nicholas O'Dea, Fiona Burnell, Anushya Chandran +1
Systems subject to high-frequency driving exhibit Floquet prethermalization, that is, they heat exponentially slowly on a time scale that is large in the drive frequency, $τ_{\rm h…
Anyon condensation in the string-net models
Chien-Hung Lin, Fiona J. Burnell
We study condensation of abelian bosons in string-net models, by constructing a family of Hamiltonians that can be tuned through any such transition. We show that these Hamiltonian…
Weak-Coupling Theory of Pair Density-Wave Instabilities in Transition Metal Dichalcogenides
Daniel Shaffer, F. J. Burnell, Rafael M. Fernandes
The possibility of realizing pair density wave (PDW) phases, in which Cooper pairs have a finite momentum, presents an interesting challenge that has been studied in a wide variety…
Composing topological domain walls and anyon mobility
Peter Huston, Fiona Burnell, Corey Jones +1
Topological domain walls separating 2+1 dimensional topologically ordered phases can be understood in terms of Witt equivalences between the UMTCs describing anyons in the bulk top…
Disordered Graphene Ribbons as Topological Multicritical Systems
Saumitran Kasturirangan, Alex Kamenev, Fiona J. Burnell
The low energy spectrum of a zigzag graphene ribbon contains two gapless bands with highly non-linear dispersion, , where is the width of the ribbon. The corr…
Playing nonlocal games with phases of quantum matter
Vir B. Bulchandani, Fiona J. Burnell, S. L. Sondhi
The parity game is an example of a nonlocal game: by sharing a Greenberger-Horne-Zeilinger (GHZ) state before playing this game, the players can win with a higher probability than…
A multi-player, multi-team nonlocal game for the toric code
Vir B. Bulchandani, Fiona J. Burnell, S. L. Sondhi
Nonlocal games yield an unusual perspective on entangled quantum states. The defining property of such games is that a set of players in joint possession of an entangled state can…
Two parameter scaling in the crossover from symmetry class BDI to AI
Saumitran Kasturirangan, Alex Kamenev, Fiona J. Burnell
The transport statistics of the 1D chain and metallic armchair graphene nanoribbons with hopping disorder are studied, with a focus on understanding the cross-over between the zero…
Anomaly Inflow for Subsystem Symmetries
Fiona J. Burnell, Trithep Devakul, Pranay Gorantla +2
We study 't Hooft anomalies and the related anomaly inflow for subsystem global symmetries. These symmetries and anomalies arise in a number of exotic systems, including models wit…
Many-body constraints and non-thermal behavior in 1D open systems with Haldane exclusion statistics
Bo Xiong, Fiona J. Burnell
We study the impact of the inter-level energy constraints imposed by Haldane Exclusion Statistics on relaxation processes in 1-dimensional systems coupled to a bosonic bath. By for…
Higher Rank Chiral Fermions in 3D Weyl Semimetals
Oleg Dubinkin, F. J. Burnell, Taylor L. Hughes
We report on exotic response properties in 3D time-reversal invariant Weyl semimetals with mirror symmetry. Despite having a vanishing anomalous Hall coefficient, we find that the…
Generalized string-net models: A thorough exposition
Chien-Hung Lin, Michael Levin, Fiona J. Burnell
We describe how to construct generalized string-net models, a class of exactly solvable lattice models that realize a large family of 2D topologically ordered phases of matter. The…
Further insights into the thermodynamics of the Kitaev honeycomb model
Kexin Feng, Natalia B. Perkins, F. J. Burnell
Here we revisit the thermodynamics of the Kitaev quantum spin liquid realized on the honeycomb lattice. We address two main questions: First, we investigate whether there are obser…
From tunnels to towers: quantum scars from Lie Algebras and q-deformed Lie Algebras
Nicholas O'Dea, Fiona Burnell, Anushya Chandran +1
We present a general symmetry-based framework for obtaining many-body Hamiltonians with scarred eigenstates that do not obey the eigenstate thermalization hypothesis. Our models ar…
Unexpected two-fold symmetric superconductivity in few-layer NbSe
Alex Hamill, Brett Heischmidt, Egon Sohn +13
Two-dimensional transition metal dichalcogenides (TMDs) have been attracting significant interest due to a range of properties, such as layer-dependent inversion symmetry, valley-c…
Do Rydberg chains yield Fibonacci anyons?
Anushya Chandran, Fiona J. Burnell, Shivaji L. Sondhi
Recent experiments have focused attention on the properties of chains of atoms in which the atoms are either in their ground states or in highly excited Rydberg states which block…
Multipolar Topological Field Theories: Bridging Higher Order Topological Insulators and Fractons
Yizhi You, F. J. Burnell, Taylor L. Hughes
Two new recently proposed classes of topological phases, namely fractons and higher order topological insulators (HOTIs), share at least superficial similarities. The wide variety…
