Dirac Equation in (1+1)-Dimensional Curved Spacetime and the Multiphoton Quantum Rabi Model
J. S. Pedernales, M. Beau, S. M. Pittman +4
We introduce an exact mapping between the Dirac equation in (1+1)-dimensional curved spacetime (DCS) and a multiphoton quantum Rabi model (QRM). A background of a (1+1)-dimensional…
Superradiant phase transition in the ultrastrong coupling regime of the two-photon Dicke model
L. Garbe, I. L. Egusquiza, E. Solano +4
The controllability of current quantum technologies allows to implement spin-boson models where two-photon couplings are the dominating terms of light-matter interaction. In this c…
Entanglement Classification with Algebraic Geometry
M. Sanz, D. Braak, E. Solano +1
We approach multipartite entanglement classification in the symmetric subspace in terms of algebraic geometry, its natural language. We show that the class of symmetric separable s…
Spectral collapse via two-phonon interactions in trapped ions
S. Felicetti, J. S. Pedernales, I. L. Egusquiza +4
Two-photon processes have so far been considered only as resulting from frequency-matched second-order expansions of light-matter interaction, with consequently small coupling stre…
Quantum Simulator for Transport Phenomena in Fluid Flows
A. Mezzacapo, M. Sanz, L. Lamata +3
Transport phenomena still stand as one of the most challenging problems in computational physics. By exploiting the analogies between Dirac and lattice Boltzmann equations, we deve…
Quantum times of arrival for multiparticle states
A. D. Baute, I. L. Egusquiza, J. G. Muga
Using the concept of crossing state and the formalism of second quantization, we propose a prescription for computing the density of arrivals of particles for multiparticle states,…
Moller operators and Lippmann-Schwinger equations for step-like potentials
A. D. Baute, I. L. Egusquiza, J. G. Muga
The Moller operators and the asociated Lippman-Schwinger equations obtained from different partitionings of the Hamiltonian for a step-like potential barrier are worked out, compar…
Sources of quantum waves
A. D. Baute, I. L. Egusquiza, J. G. Muga
Due to the space and time dependence of the wave function in the time dependent Schroedinger equation, different boundary conditions are possible. The equation is usually solved as…
Consistent histories, the quantum Zeno effect, and time of arrival
I. L. Egusquiza, J. G. Muga
We present a decomposition of the general quantum mechanical evolution operator, that corresponds to the path decomposition expansion, and interpret its constituents in terms of th…
Time-of-arrival distribution for arbitrary potentials and Wigner's time-energy uncertainty relation
A. D Baute, R. Sala Mayato, J. P. Palao +2
A realization of the concept of "crossing state" invoked, but not implemented, by Wigner, allows to advance in two important aspects of the time of arrival in quantum mechanics: (i…
