Forms of BRST symmetry on a Prototypical First-Class System
Sumit Kumar Rai, Bhabani Prasad Mandal, Ronaldo Thibes
We obtain the various forms of BRST symmetry by using the Batalin-Fradkin-Vilkovisky formalism in a prototypical first class system. We have shown that the various forms of symmetr…
Reduced-order Bopp-Podolsky model on the null-plane
Mario C. Bertin, Ronaldo Thibes
We consider the null-plane dynamics for a reduced-order version of the higher-derivatives Bopp-Podoslky generalized electrodynamics model. By introducing an auxiliary vector field,…
Symplectic Quantization and General Constraint Structure of a Prototypical Second-Class System
Ignacio S. Gomez, Vipul Kumar Pandey, Ronaldo Thibes
We discuss a general prototypical constrained Hamiltonian system with a broad application in quantum field theory and similar contexts where dynamics is defined through a functiona…
Small mass graviton propagator via finite-field-dependent BRST transformations in the critical dimension Siegel-Zwiebach action from string theory
Vipul Kumar Pandey, Ronaldo Thibes
We discuss the divergent graviton propagator massless limit problem in and show how it can be rigorously approached by interconnecting distinct gauge-fixed Siegel-Zwiebach g…
Note on an extended chiral bosons system contextualized in a modified gauge-unfixing formalism
Gabriella V. Ambrosio, Cleber N. Costa, Paulo R. F. Alves +2
We analyze the Hamiltonian structure of an extended chiral bosons theory in which the self-dual constraint is introduced via a control -parameter. The system has two second-clas…
Modified gauge unfixing formalism and gauge symmetries in the non-commutative chiral bosons theory
Cleber N. Costa, Gabriella V. Ambrósio, Paulo R. F. Alves +2
We use the gauge unfixing (GU) formalism framework in a two dimensional noncommutative chiral bosons (NCCB) model to disclose new hidden symmetries. That amounts to converting a se…
Gauge Symmetry of the Chiral Schwinger model from an improved Gauge Unfixing formalism
Gabriella V. Ambrosio, Cleber N. Costa, Paulo R. F. Alves +3
In this paper, the Hamiltonian structure of the bosonized chiral Schwinger model (BCSM) is analyzed. From the consistency condition of the constraints obtained from the Dirac metho…
Improved Gauge-Unfixing Formalism through a Prototypical Second-Class System
Jorge Ananias Neto, Widervan de Deus Morais, Ronaldo Thibes
We contextualize the improved gauge-unfixing (GU) formalism within a rather general prototypical second-class system, obtaining a corresponding first-class equivalent description e…
New Forms of BRST Symmetry on a Prototypical First-Class System
Bhabani Prasad Mandal, Sumit Kumar Rai, Ronaldo Thibes
We scrutinize the many known forms of BRST symmetries, as well as some new ones, realized within a prototypical first-class system. Similarities and differences among ordinary BRST…
BFV quantization and BRST symmetries of the gauge invariant fourth-order Pais-Uhlenbeck oscillator
Bhabani Prasad Mandal, Vipul Kumar Pandey, Ronaldo Thibes
We perform the BFV-BRST quantization of the fourth-order Pais-Uhlenbeck oscillator (PUO). We show that although the PUO is not naturally constrained in the sense of Dirac-Bergmann,…
BFFT Nonlinear Constraints Abelianization of a Prototypical Second-Class System
Vipul Kumar Pandey, Ronaldo Thibes
We apply the BFFT formalism to a prototypical second-class system, aiming to convert its constraints from second- to first-class. The proposed system admits a consistent initial se…
First-Order Gauge Invariant Generalization of the Quantum Rigid Rotor
Suzicleide L. de Oliveira, Camila M. B. Santos, Ronaldo Thibes
A first-order gauge invariant formulation for the two-dimensional quantum rigid rotor is long known in the theoretical physics community as an isolated peculiar model. Parallel to…
Conic Constrained Particle Quantization within the DB, FJBW and BRST Approaches
Gabriel D. Barbosa, Ronaldo Thibes
We consider a second degree algebraic curve describing a general conic constraint imposed on the motion of a massive spinless particle. The problem is trivial at classical level bu…
Reduced Order Podolsky Model
Ronaldo Thibes
We perform the canonical and path integral quantizations of a lower-order derivatives model describing Podolsky's generalized electrodynamics. The physical content of the model sho…
