Exact solution and coherent states of an asymmetric oscillator with position-dependent mass
Bruno G. da Costa, Ignacio S. Gomez, Biswanath Rath
We revisit the problem of the deformed oscillator with position-dependent mass [da Costa et al., J. Math. Phys. {\bf 62}, 092101 (2021)] in the classical and quantum formalisms, by…
Scalar fields and Lifshitz black holes from Derrick's theorem evasion
D. C. Moreira, F. A Brito, J. C. Mota-Silva
We study classical scalar fields in asymptotically Lifshitz spacetimes. By evading Derrick's theorem requiring the scalar potential to explicitly depend on the background coordinat…
Supersymmetric quantum mechanics and coherent states for a deformed oscillator with position-dependent effective mass
Bruno G. da Costa, Genilson A. C. da Silva, Ignacio S. Gomez
We study the classical and quantum oscillator in the context of a non-additive (deformed) displacement operator, associated with a position-dependent effective mass, by means of th…
AdS/BCFT correspondence and BTZ black hole thermodynamics within Horndeski gravity
Fabiano F. Santos, Eduardo Folco Capossoli, Henrique Boschi-Filho
In this work, we study gravity duals of conformal field theories with boundaries known as AdS/BCFT correspondence, put forward by Takayanagi [1], within a scalar-tensor theory, as…
Deformation of loops in 2D packing of flexible rods
T. A. Sobral, V. H. de Holanda, F. C. B. Leal +1
The injection of a long flexible rod into a two-dimensional domain yields a complex pattern commonly studied through elasticity theory, packing analysis, and fractal geometries. "L…
-Deformed quantum and classical mechanics for a system with position-dependent effective mass
Bruno G. da Costa, Ignacio S. Gomez, Mariela Portesi
We present the quantum and classical mechanics formalisms for a particle with position-dependent mass in the context of a deformed algebraic structure (named -algebra), motivate…
Revisiting the tensor meson spectrum
L. M. Abreu, F. M. da Costa Júnior, A. G. Favero
This work is devoted to the discussion and characterization of the tensor meson spectrum, by making use of the Coulomb gauge Hamiltonian approach to QCD, with the intera…
Lifshitz-scaling in CPT-even Lorentz-violating electrodynamics and GRB time delay
K. E. L. de Farias, T. A. M. Sampaio, M. A. Anacleto +2
In this work, we consider the Hořava-Lifshitz scaling to rewrite higher-order derivatives in Lorentz-violating CPT-even electrodynamics. The possibility of the Lorentz invariance v…
Consistency analysis of a CPT-even and CPT-odd lorentz-violating effective field theory in the electrodynamics at Planck scale by an influence of a background isotropic field
T. A. M. Sampaio, E. Passos
Based on the motivation that some quantum gravity theories predicts the Lorentz Invariance Violation (LIV) around Planck-scale energy levels, this paper proposes a new formalism th…
Information-theoretic measures for a position-dependent mass system in an infinite potential well
Bruno G. da Costa, Ignacio S. Gomez
In this work we calculate the Cramér-Rao, the Fisher-Shannon and the López-Ruiz-Mancini-Calbert (LMC) complexity measures for eigenstates of a deformed Schrödinger equation, being…
Majorization and dynamics of continuous distributions
Ignacio S. Gomez, Bruno G. da Costa, M. A. F. dos Santos
In this work we show how the concept of majorization in continuous distributions can be employed to characterize chaotic, diffusive and quantum dynamics. The key point lies in that…
Deformed Fokker-Planck equation: inhomogeneous medium with a position-dependent mass
Bruno G. da Costa, Ignacio S. Gomez, Ernesto P. Borges
We present the Fokker-Planck equation (FPE) for an inhomogeneous medium with a position-dependent mass particle by making use of the Langevin equation, in the context of a generali…
A position-dependent mass harmonic oscillator and deformed space
Bruno G. da Costa, Ernesto P. Borges
We consider canonically conjugated generalized space and linear momentum operators and in quantum mechanics, associated to a generalized translation operat…
Inertial and topological effects on a 2D electron gas
Julio Brandão, Cleverson Filgueiras, Moises Rojas +1
In this work, we study how the combination of rotation and a topological defect can influence the energy spectrum of a two dimensional electron gas in a strong perpendicular magnet…
Generalized space and linear momentum operators in quantum mechanics
Bruno G. da Costa, Ernesto P. Borges
We propose a modification of a recently introduced generalized translation operator, by including a -exponential factor, which implies in the definition of a Hermitian deformed…
