Unearthing wave-function renormalization effects in the time evolution of a Bose-Einstein condensate

Paolo Facchi, Saverio Pascazio, Francesco V. Pepe +3

We study the time evolution of a Bose-Einstein condensate in an accelerated optical lattice. When the condensate has a narrow quasimomentum distribution and the optical lattice is…

Quantum Zeno dynamics of a field in a cavity

Jean-Michel Raimond, Paolo Facchi, Bruno Peaudecerf +6

We analyze the quantum Zeno dynamics that takes place when a field stored in a cavity undergoes frequent interactions with atoms. We show that repeated measurements or unitary oper…

An algebraic approach to the study of multipartite entanglement

S. Di Martino, B. Militello, A. Messina

A simple algebraic approach to the study of multipartite entanglement for pure states is introduced together with a class of suitable functionals able to detect entanglement. On th…

Generalized quantum tomographic maps

M. Asorey, P. Facchi, V. I. Man'ko +3

Some non-linear generalizations of classical Radon tomography were recently introduced by M. Asorey et al [Phys. Rev. A 77, 042115 (2008), where the straight lines of the standard…

A measurement scheme for purity based on two two-body gates

Hiromichi Nakazato, Toru Tanaka, Kazuya Yuasa +2

A scheme for measuring the purity of a quantum system with a finite number of levels is presented. The method makes use of two square root of SWAP gates and only hinges on measurem…

Invariant measures on multimode quantum Gaussian states

C. Lupo, S. Mancini, A. De Pasquale +3

We derive the invariant measure on the manifold of multimode quantum Gaussian states, induced by the Haar measure on the group of Gaussian unitary transformations. To this end, by…

Wave Function Renormalization Effects in Resonantly Enhanced Tunneling

N. Lörch, F. V. Pepe, H. Lignier +8

We study the time evolution of ultra-cold atoms in an accelerated optical lattice. For a Bose- Einstein condensate with a narrow quasi-momentum distribution in a shallow optical la…

Measuring quantumness via anticommutators

Rosario Fazio, Kavan Modi, Saverio Pascazio +2

We introduce a method to witness the quantumness of a system. The method relies on the fact that the anticommutator of two classical states is always positive. We show that there i…
