Exact Solutions to the Motion of Two Charged Particles in Lineal Gravity
R. B. Mann, D. Robbins, T. Ohta +1
We extend the canonical formalism for the motion of -particles in lineal gravity to include charges. Under suitable coordinate conditions and boundary conditions the determining…
Exact Solutions of Relativistic Two-Body Motion in Lineal Gravity
R. B. Mann, D. Robbins, T. Ohta
We develop the canonical formalism for a system of bodies in lineal gravity and obtain exact solutions to the equations of motion for N=2. The determining equation of the Hamil…
Orbifolds by 2-groups and decomposition
T. Pantev, D. Robbins, E. Sharpe +1
In this paper we study three-dimensional orbifolds by 2-groups with a trivially-acting one-form symmetry group BK. These orbifolds have a global two-form symmetry, and so one expec…
Quantum symmetries in orbifolds and decomposition
D. Robbins, E. Sharpe, T. Vandermeulen
In this paper, we introduce a new set of modular-invariant phase factors for orbifolds with trivially-acting subgroups, analogous to discrete torsion and generalizing quantum symme…
Anomaly resolution via decomposition
D. Robbins, E. Sharpe, T. Vandermeulen
In this paper we apply decomposition to orbifolds with quantum symmetries to resolve anomalies. Briefly, it has been argued by e.g. Wang-Wen-Witten, Tachikawa that an anomalous orb…
Anomaly resolution by non-invertible symmetries
A. Perez-Lona, D. Robbins, S. Roy +3
In this paper we generalize previous results on anomaly resolution to noninvertible symmetries. Briefly, given a global symmetry G of some theory with a 't Hooft anomaly rendering…
Exact Relativistic Two-Body Motion in Lineal Gravity
R. B. Mann, D. Robbins, T. Ohta
We consider the N-body problem in (1+1) dimensional lineal gravity. For 2 point masses (N=2) we obtain an exact solution for the relativistic motion. In the equal mass case we obta…
Notes on gauging noninvertible symmetries, part 1: Multiplicity-free cases
A. Perez-Lona, D. Robbins, E. Sharpe +2
In this paper we discuss gauging noninvertible zero-form symmetries in two dimensions. We specialize to certain gaugeable cases, specifically, fusion categories of the form Rep(H)…
