Carrollian Wave Equations for Arbitrary Spin: Anyons and the Exotic Particle on the Noncommutative Plane
Mauricio Valenzuela
We construct the Carrollian limit of the Cortés--Plyushchay wave equations for planar anyons, grading the spin-tower components by powers of and taking the limit at fixed rest…
Interacting Galilean and Finite-Energy Carroll Fermions
Pulastya Parekh, Aditya Sharma, Mauricio Valenzuela
We present a unified derivation of the Galilean and Carrollian limits of the massive Dirac action based on a similarity transformation depending on the mass and the speed of light.…
Quantization of counterexamples to Dirac's conjecture
Mauricio Valenzuela
Dirac's conjecture, that secondary first-class constraints generate transformations that do not change the physical system's state, has various counterexamples. Since no matching g…
Massless Rarita-Schwinger equations: Half and three halves spin solution
Mauricio Valenzuela, Jorge Zanelli
Counting the degrees of freedom of the massless Rarita-Schwinger theory is revisited using Behrends-Fronsdal projectors. The identification of the gauge invariant part of the vecto…
Gauge and time-reparametrization invariant spin-half fields
Mauricio Valenzuela
We present a fermion model characterized by an anticommuting-parameter shift symmetry. The Hamiltonian formulation exhibits a combination of first-class and second-class constraint…
Pseudoclassical system with gauge and time-reparametrization invariance
Mauricio Valenzuela
We present a pseudoclassical mechanics model which exhibits gauge symmetry and time-reparametrization invariance. As such, first- and second-class constraints restrict the phase sp…
