The Casimir-Lifshitz formula for rectangular dielectric waveguide
E. Arias, G. O. Heymans, N. F. Svaiter
We analyze the Casimir-Lifshitz effect associated with the electromagnetic field in the presence of a rectangular waveguide consisting of two distinct dielectric materials in a $(3…
The vacuum energy with non-ideal boundary conditions via an approximate functional equation
E. Arias, G. O. Heymans, H. T. Lopes +1
We discuss the vacuum energy of a quantized scalar field in the presence of classical surfaces, defining bounded domains , where the field satisfies idea…
Spin-polarized current, spin-transfer torque and spin Hall effect in presence of an electromagnetic non-minimal coupling
Rodrigo Turcati, Carlos Andres Bonilla Quintero, José Abdalla Helayël-Neto +1
In this contribution, we start off from a fully relativistic description of a single electron non-minimally coupled to an external electromagnetic field. Making direct use of the f…
Enhancement of efficiency in the Dicke model quantum heat engine
M. Aparicio Alcalde, E. Arias, N. F. Svaiter
We analyze a quantum heat engine described by the full Dicke model. The system exhibit quantum phase transitions under certain conditions. We consider the system performing a Stirl…
The Unruh Quantum Otto Engine
Enrique Arias, Thiago R. de Oliveira, M. S. Sarandy
We introduce a quantum heat engine performing an Otto cycle by using the thermal properties of the quantum vacuum. Since Hawking and Unruh, it has been established that the vacuum…
Gauge fields in graphene with nonuniform elastic deformations: A quantum field theory approach
Enrique Arias, Alexis R. Hernández, Caio Lewenkopf
We investigate the low energy continuum limit theory for electrons in a graphene sheet under strain. We use the quantum field theory in curved spaces to analyze the effect of the s…
