Spectroscopic Probe of the van der Waals Interaction between Polar Molecules and a Curved Surface

Giuseppe Bimonte, Thorsten Emig, Robert L. Jaffe +1

We study the shift of rotational levels of a diatomic polar molecule due to its van der Waals (vdW) interaction with a gently curved dielectric surface at temperature , and subm…

Exact Casimir interaction of perfectly conducting three-spheres in four euclidean dimensions

Giuseppe Bimonte

Exploiting conformal symmetry, we derive a simple exact formula for the classical electromagnetic Casimir interaction of two perfectly conducting three-spheres, including the spher…

Optimal uncertainty relations in a modified Heisenberg algebra

Kais Abdelkhalek, Wissam Chemissany, Leander Fiedler +2

Various theories that aim at unifying gravity with quantum mechanics suggest modifications of the Heisenberg algebra for position and momentum. From the perspective of quantum mech…

Non-Gaussian entanglement swapping

F. Dell'Anno, D. Buono, G. Nocerino +2

We investigate the continuous-variable entanglement swapping protocol in a non-Gaussian setting, with non- Gaussian states employed either as entangled inputs and/or as swapping re…

Time, classical and quantum

Paolo Aniello, Florio Maria Ciaglia, Fabio Di Cosmo +2

We propose a new point of view regarding the problem of time in quantum mechanics, based on the idea of replacing the usual time operator with a suitable real-valued f…

Weyl-gauge invariant proof of the Spin-Statistics Theorem

Enrico Santamato, Francesco De Martini

The traditional standard theory of quantum mechanics is unable to solve the spin-statistics problem, i.e. to justify the utterly important \qo{Pauli Exclusion Principle} but by the…

The quantum-to-classical transition: contraction of associative products

A. Ibort, V. I. Man'ko, G. Marmo +3

The quantum-to-classical transition is considered from the point of view of contractions of associative algebras. Various methods and ideas to deal with contractions of associative…

Characterizing the dynamical semigroups that do not decrease a quantum entropy

Paolo Aniello, Dariusz Chruscinski

In finite dimensions, we provide characterizations of the quantum dynamical semigroups that do not decrease the von Neumann, the Tsallis and the Renyi entropies, as well as a famil…
