Dirac equation exact solutions for generalized asymmetrical Hartmann potentials
Alvaro de Souza Dutra, M. B. Hott
In this work we solve the Dirac equation by constructing the exact bound state solutions for a mixing of vector and scalar generalized Hartmann potentials. This is done provided th…
Ordering ambiguity versus representation
Alvaro de Souza Dutra
In this work we show that the ordering ambiguity on quantization depends on the representation choice. This property is then used to solve unambiguously some particular systems. Fi…
Nonlocality without inequalities
GianCarlo Ghirardi, Luca Marinatto
We prove that every conceivable hidden variable model reproducing the quantum mechanical predictions of almost any entangled state must necessarily violate Bell's locality conditio…
Quantum and Thermal Corrections to a Classically Chaotic Dissipative System
M. Rodriguez-Achach, G. Perez, H. Cerdeira
The effects of quantum and thermal corrections on the dynamics of a damped nonlinearly kicked harmonic oscillator are studied. This is done via the Quantum Langevin Equation formal…
General criterion for the entanglement of two indistinguishable particles
GianCarlo Ghirardi, Luca Marinatto
We relate the notion of entanglement for quantum systems composed of two identical constituents to the impossibility of attributing a complete set of properties to both particles.…
Quantum dynamics in single spin measurement
Stefano Mancini, David Vitali, Hector Moya-Cessa
We study the quantum dynamics of a model for the single-spin measurement in magnetic-resonance force microscopy. We consider an oscillating driven cantilever coupled with the magne…
