New paper on non-Markovianity for QTeQ

New results from the collaboration between QTeQ members and the University of Calabria and Palermo, on non-Markovian open system dynamics of quantum systems have been published in Phys. Rev. A recently.

Tony (joint postdoc in Cosenza and Belfast), Carlo (now at ICL and honorary perpetual member of QTeQ), and Mauro have worked with Salvatore Lorenzo (Palermo) and Francesco Plastina (Calabria) on aspects of the hierarchy among different measures of non-Markovianity for a system exposed to competing environmental effects. The results of the work have appeared in

Tony J. G. Apollaro, Salvatore Lorenzo, Carlo Di Franco, Francesco Plastina, and Mauro Paternostro, Competition between memory-keeping and memory-erasing decoherence channels, Phys. Rev. A 90, 012310 (2014)

New paper in J. Stat. Mech. for Gabriele and Giacomo!!

In the enduring effort performed at QTeQ to explore the link between the physics of quantum many-body systems and the features of quantum entanglement, Gabriele and the group’s honorary member Giacomo Torlai (LMU Munich), have recently published a new article in J. Stat. Mech., which is the reference journal of the community interested in statistical mechanics (including the quantum scenario). Details of the work, which is a result of Gabriele’s collaboration with Luca Tagliacozzo (ICFO Barcelona), can be found in

G Torlai, L Tagliacozzo, and G. De Chiara, Dynamics of the entanglement spectrum in spin chains, J. Stat. Mech. P06001 (2014)

which is a contribution to the journal’s special issue on “Quantum Entanglement in Condensed Matter Physics”. Congratulations to both Giacomo and Gabriele!!

New QTeQ’s PRL

A new paper has been published in Phys. Rev. Lett. as a collaboration between the University of Trieste, University of Southampton, and QTeQ.
A non-interferometric method, entirely based on the modifications experienced by the massive oscillating mirror of an optomechanical cavity, has been proposed by Mohammad Bahrami, Angelo Bassi, Hendrik Ulbricht, and Mauro to study possible corrections to Schroedinger equations embodied by the so-called Continuous Spontaneous Localization model.

Details of the work can be found in

M. Bahrami, M. Paternostro, A. Bassi, and H. Ulbricht, Proposal for a Noninterferometric Test of Collapse Models in Optomechanical Systems,
Phys. Rev. Lett. 112, 210404 (2014)

The paper has been picked as an Editors’ Suggestion in Phys. Rev. Lett., which is the third time for QTeQ.
