Constraining tachyonic inflationary β-exponential model with Continuous Spontaneous Localization collapse scheme
F. A. Brito, Julio C. M. Rocha, A. S. Lemos +1
In this work, we consider the dynamics of the self-induced collapse of the tachyon wave function in inflationary scenarios. We analyze the modifications on the power spectrum by co…
Emergence of squeezed coherent states in Kaluza-Klein cosmology
A. S. Lemos, A. S. Pereira, F. A. Brito +1
In this work, we consider a propagating scalar field on Kaluza-Klein-type cosmological background. It is shown that this geometrical description of the Universe resembles - from a…
Squeezed coherent states for a free particle with time-varying mass
A. S. Pereira, A. S. Lemos, F. A. Brito
We obtain the squeezed coherent states (SCS) for a free particle with exponentially time-varying mass. We write these states in terms of the squeeze and displacement parameters on…
Time-dependent coherent squeezed states in a nonunitary approach
A. S. Pereira, A. S. Lemos
In this work, we have applied the integrals of motion method in a nonunitary approach and so obtained the time-dependent displacement and squeezed parameters of the coherent squeez…
Coherent and Semiclassical States of a Charged Particle in a Constant Electric Field
T. C. Adorno, A. S. Pereira
The method of integrals of motion is used to construct families of generalized coherent states of a nonrelativistic spinless charged particle in a constant electric field. Families…
Coherent and semiclassical states of a charged particle in electromagnetic fields
A. S. Pereira
In the present article we extend our study (BJP 45 (2015) 369) of generalized coherent states (GCS) of a one-dimensional particle considering such important physical system as a 3-…
