Researchers working with cold atoms begin to be interested in questions that preoccupied the condensed matter field for a long time: systems with strong correlation, entanglement, and coherence.<\/p>\n<p>We hope that these new researches will lead to a better understanding of high-temperature superconductivity. The field of quantum transport which deals with waves of matter (electrons or atoms) spreading under the influence of several forces in a solid or in a laser beam, appears as new field in between those two communities.<\/p>\n<p>This theme aims at promoting the researches on these fields thanks to collaborations between condensed matter and atomic, molecular and optical physics. This theme will more precisely shed light on :<\/p>\n<ul>\n<li>Quantum information : elementary quantum systems ( atoms, ions, molecules, NV centres for diamonds, artificial atoms used as superconducting electrical circuits, cold atoms quantum simulators, qubits photonics. Quantum technologies (cryptography).<\/li>\n<li>Coherence and correlations: control of decoherence mechanisms in mesoscopic conductors, graphene, highly correlated electrons, superconductivity, unconventional superconductivity, spin liquids, cold matter.<\/li>\n<li>Topological phases studies (Orbit spin coupling, Edge states in oxides and cold atoms), High-temperature superconductivity (Pseudogaps, Spin waves), Ferroelectricity<\/li>\n<\/ul>\n<\/div>\n<table border=\"0\">\n<tbody>\n<tr>\n<td style=\"text-align: justify; border: 1px solid #ffffff; width: 400px;\" rowspan=\"2\"><span style=\"font-size: 8pt;\"><img decoding=\"async\" loading=\"lazy\" class=\" size-full wp-image-158\" style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/www.labex-palm.fr\/wp-content\/uploads\/2013\/07\/Capture_decran_2013-07-02_a_09.49.13.png\" alt=\"Capture_decran_2013-07-02_a_09.49.13\" width=\"250\" height=\"180\" \/><\/span><span style=\"font-size: 8pt;\">Interf\u00e9rom\u00e8tre Mach-Zehnder dans lequel un \u00e9lectron en r\u00e9gime de Hall quantique r\u00e9v\u00e8le des interf\u00e9rences analogues \u00e0 celle d&#8217;un dispositif optique.
