Macroscopic quantum superpositions in superconducting circuits
Vitoria A. de Souza, Caio C. Holanda Ribeiro, Vitorio A. De Lorenci
A possible route to test whether macroscopic systems can acquire quantum features using superconducting circuits is here presented. It is shown that under general assumptions a cla…
Quantum Brownian motion of a scalar particle in the presence of a partially reflecting boundary
C. C. H. Ribeiro, V. A. De Lorenci
The second quantization of a real massless scalar field in the presence of a material medium described by a Drude-like susceptibility is here examined in a 1+1 dimensional model. T…
Anisotropic motion of an electric dipole in a photon gas near a flat conducting boundary
G. H. S. Camargo, V. A. De Lorenci, A. L. Ferreira Junior +1
The quantum Brownian motion of a single neutral particle with nonzero electric dipole moment placed in a photon gas at fixed temperature and close to a conducting wall is here exam…
Probing thermal fluctuations through scalar test particles
G. H. S. Camargo, V. A. De Lorenci, A. L. Ferreira Junior +1
The fundamental vacuum state of quantum fields, related to Minkowski space, produces divergent fluctuations that must be suppressed in order to bring reality to the description of…
Classical enhancement of quantum vacuum fluctuations
V. A. De Lorenci, L. H. Ford
We propose a mechanism for the enhancement of vacuum fluctuations by means of a classical field. The basic idea is that if an observable quantity depends quadratically upon a quant…
Quantum Brownian motion near a point-like reflecting boundary
V. A. De Lorenci, E. S. Moreira, M. M. Silva
The Brownian motion of a test particle interacting with a quantum scalar field in the presence of a perfectly reflecting boundary is studied in (1 + 1)-dimensional flat spacetime.…
