Casimir effect for a massive scalar field confined between parallel plates with a spatially varying effective mass
R. L. Araújo Xavier, M. H. B. Chaves, E. R. Bezerra de Mello +1
We investigate the Casimir effect for a massive real scalar field confined between two perfectly reflecting parallel plates in the presence of a position-dependent effective mass,…
Vacuum Energy and Topological Mass from a Constant Magnetic Field and Boundary Conditions in Coupled Scalar Field Theories
A. J. D. Farias Junior, Andrea Erdas, Herondy F. Santana Mota
We investigate the combined effects of a uniform magnetic field and boundary conditions on vacuum energy and topological mass generation in a coupled scalar field theory. The syste…
Boundary effects in classical liquid density fluctuations at finite temperature
Herondy Mota, K. E. L. de Farias
We investigate thermal effects on density fluctuations in confined classical liquids using phonon quantization. The system is modeled via a massless scalar field between perfectly…
Finite temperature Casimir effect for a spinor field in cosmic dispiration spacetime
Joás Venâncio, Herondy Mota, Azadeh Mohammadi
This study explores the finite temperature Casimir effect for a massive spinor field in cosmic dispiration spacetime, formed by the combination of a cosmic string and a screw dislo…
Vacuum energy, temperature corrections and heat kernel coefficients in -dimensional spacetimes with nontrivial topology
Herondy Mota
In this work we make use of the generalized zeta function technique to investigate the vacuum energy, temperature corrections and heat kernel coefficients associated with a scalar…
