The group structure of dynamical transformations between quantum reference frames

Angel Ballesteros, Flaminia Giacomini, Giulia Gubitosi

Recently, it was shown that when reference frames are associated to quantum systems, the transformation laws between such quantum reference frames need to be modified to take into…

Some results on the rotated infinitely deep potential and its coherent states

Fabio Bagarello

The Swanson model is an exactly solvable model in quantum mechanics with a manifestly non self-adjoint Hamiltonian whose eigenvalues are all real. Its eigenvectors can be deduced e…

Nonlinear Description of Quantum Dynamics. Generalized Coherent States

Hans Cruz-Prado, Giuseppe Marmo, Dieter Schuch +1

In this work it is shown that there is an inherent nonlinear evolution in the dynamics of the so-called generalized coherent states. To show this, the immersion of a classical mani…

Lagrangian description of Heisenberg and Landau-von Neumann equations of motion

Florio M. Ciaglia, Fabio Di Cosmo, Alberto Ibort +3

An explicit Lagrangian description is given for the Heisenberg equation on the algebra of operators of a quantum system, and for the Landau-von Neumann equation on the manifold of…

Schwinger's Picture of Quantum Mechanics IV: Composition and independence

Florio M. Ciaglia, Fabio Di Cosmo, Alberto Ibort +1

The groupoids description of Schwinger's picture of quantum mechanics is continued by discussing the closely related notions of composition of systems, subsystems, and their indepe…

Going beyond Local and Global approaches for localized thermal dissipation

Donato Farina, Giulio De Filippis, Vittorio Cataudella +2

Identifying which master equation is preferable for the description of a multipartite open quantum system is not trivial and has led in the recent years to the local vs. global deb…

Geometry from divergence functions and complex structures

Florio M. Ciaglia, Fabio Di Cosmo, Armando Figueroa +2

Motivated by the geometrical structures of quantum mechanics, we introduce an almost-complex structure on the product of any parallelizable statistical manifold …

Transition Probabilities in Generalized Quantum Search Hamiltonian Evolutions

Steven Gassner, Carlo Cafaro, Salvatore Capozziello

A relevant problem in quantum computing concerns how fast a source state can be driven into a target state according to Schrödinger's quantum mechanical evolution specified by a su…
