Symmetric Gapped Interfaces of SPT and SET States: Systematic Constructions
Symmetry-protected topological (SPT) states have boundary ’t Hooft anomalies that obstruct the effective boundary theory realized in its own dimension with UV completion and with an on-site G-symmetry.

Suppressing nonperturbative gauge errors in the thermodynamic limit using local pseudogenerators [PDF]
With recent progress in quantum simulations of lattice-gauge theories, it is becoming a pressing question how to reliably protect the gauge symmetry that defines such models.

Reducible gauge symmetry versus unfree gauge symmetry in Hamiltonian formalism
The unfree gauge symmetry implies that gauge variation of the action functional vanishes provided for the gauge parameters are restricted by the differential equations.

Discrete theta angles, symmetries and anomalies
Gauge theories in various dimensions often admit discrete theta angles, that arise from gauging a global symmetry with an additional symmetry protected topological (SPT) phase.

We argue that Left-Right parity symmetry $${\mathcal {P}}$$ P can arise as a discrete remnant of a unified gauge symmetry. The high-energy unification necessarily includes the gauging of the Lorentz symmetry, bringing into the game gravitational ...

Symmetry-enriched quantum spin liquids in (3 + 1)d
We use the intrinsic one-form and two-form global symmetries of (3+1)d bosonic field theories to classify quantum phases enriched by ordinary (0-form) global symmetry. Different symmetry-enriched phases correspond to different ways of coupling the theory

Fractons, dipole symmetries and curved spacetime
We study complex scalar theories with dipole symmetry and uncover a no-go theorem that governs the structure of such theories and which, in particular, reveals that a Gaussian theory with linearly realised dipole symmetry must be Carrollian.

Gauge symmetry breaking in gauge theories---In search of clarification [PDF]
The paper investigates the spontaneous breaking of gauge symmetries in gauge theories from a philosophical angle, taking into account the fact that the notion of a spontaneously broken local gauge symmetry, though widely employed in textbook expositions ...

A note on unfree gauge symmetry
We study the general structure of field theories with the unfree gauge symmetry where the gauge parameters are restricted by differential equations.

5D N=1 super QFT: Symplectic quivers
We develop a method to build new 5D N=1 gauge models based on Sasaki-Einstein manifolds Yp,q. These models extend the standard 5D ones having a unitary SU(p)q gauge symmetry based on Yp,q.
