Exact classical limit of the quantum bouncer
Juan A. Cañas, J. Bernal, A. Martín-Ruiz
In this paper we develop a systematic approach to determine the classical limit of periodic quantum systems and applied it successfully to the problem of the quantum bouncer. It is…
Testing the scalar sector of the Standard-Model Extension with neutron gravity experiments
C. A. Escobar, A. Martín-Ruiz, A. M. Escobar-Ruiz +1
In the present study we analyse, within the scalar sector of the Standard-Model Extension (SME) framework, the influence of a spontaneous Lorentz symmetry breaking on gravitational…
Testing the equivalence principle with time-diffracted free-falling quantum particles
Juan A. Cañas, J. Bernal, A. Martín-Ruiz
The equivalence principle of gravity is examined at the quantum level using the diffraction in time of matter waves in two ways. First, we consider a quasi-monochromatic beam of pa…
Ground state and polarization of an hydrogen-like atom near a Weyl semimetal
Jorge David Castaño-Yepes, D. J. Nader, A. Martín-Ruiz
In this paper we study the effects of a topological Weyl semimetal (WSM) upon the ground state and polarization of an hydrogen-like atom near its surface. The WSM is assumed to be…
