However, realizations of quantum many-body systems which are both well isolated from their environment and accessible to experimental study are scarce. In recent years, the field has experienced rapid progress, partly attributed to ultra-cold atoms. This book presents the experimental study of a relaxation phenomenon occurring in a one-dimensional bosonic Josephson junction. The system consists of two 1D quasi Bose-Einstein condensates of 87Rb, magnetically trapped on an atom chip. Using radio-frequency dressing, the author deforms a single harmonic trap, in which the atoms are initially condensed, into a double-well potential and realizes a splitting of the wave function. A large spatial separation and a tilt of the double-well enable the preparation of a broad variety of initial states by precisely adjusting the initial population and relative phase of the two wave packets, while preserving the phase coherence. By re-coupling the two wave packets, the author investigates tunneling regimes such as Josephson (plasma) oscillations and macroscopic quantum self-trapping. In both regimes, the tunneling dynamics exhibits a relaxation to a phase-locked equilibrium state contradicting theoretical predictions. The experimental results are supported with an empirical model that allows quantitative discussions according to various experimental parameters. These results illustrate how strongly the non-equilibrium dynamics differ from the equilibrium one, which is well described by thermodynamics and statistical physics. . 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aQuantum theory 606 $aCondensed matter 606 $aLow temperatures 606 $aLow temperatures 606 $aQuantum Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19080 606 $aCondensed Matter Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25005 606 $aLow Temperature Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25130 615 0$aQuantum theory. 615 0$aCondensed matter. 615 0$aLow temperatures. 615 0$aLow temperatures. 615 14$aQuantum Physics. 615 24$aCondensed Matter Physics. 615 24$aLow Temperature Physics. 676 $a621.35 700 $aPigneur$b Marine$4aut$4http://id.loc.gov/vocabulary/relators/aut$0843416 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910427689703321 996 $aNon-equilibrium Dynamics of Tunnel-Coupled Superfluids$91882034 997 $aUNINA LEADER 02996oas 2200937 a 450 001 9910516102203321 005 20251106213014.0 011 $a1706-9211 035 $a(OCoLC)50928566 035 $a(CONSER)cn2002704215 035 $a(CKB)991042735570520 035 $a(EXLCZ)99991042735570520 100 $a20021105a20029999 ua b 101 0 $afre 135 $aurcn||||||||| 181 $ctxt$2rdacontent/fre 182 $cc$2rdamedia/fre 200 10$aGuide statistique de l'e?nergie 210 $aOttawa $cStatistique Canada$d©2000- 300 $aTitre de l'e?cran-titre (visionne? le 30 sept. 2002). 300 $aArchive? par la Bibliothe?que nationale du Canada. 311 08$a1496-4619 531 0 $aGuide stat. e?nergie 606 $aPower resources$zCanada$vStatistics$vPeriodicals 606 $aRessources e?nerge?tiques$zCanada$vStatistiques$vPe?riodiques 606 $aPower resources$2fast$3(OCoLC)fst01074275 606 $aApprovisionnement e?nerge?tique$2rasuqam 606 $aConsommation d'e?nergie$2rasuqam 606 $aProduction e?nerge?tique$2rasuqam 606 $aIndicateur e?conomique$2rasuqam 606 $aRessources e?nerge?tiques$2rasuqam 607 $aCanada$2fast$1https://id.oclc.org/worldcat/entity/E39PBJkMHVW4rfVXPrhVP4VwG3 607 $aCanada$2rasuqam 608 $aStatistics. 608 $aGovernment Publication. 608 $aserials (publications)$2aat 608 $apublic records.$2aat 608 $aSerial publications.$2fast 608 $aPeriodicals.$2fast 608 $aStatistics.$2fast 608 $aSerial publications.$2lcgft 608 $aStatistics.$2lcgft 608 $aPe?riodique e?lectronique (Descripteur de forme)$2rasuqam 608 $aRessource Internet (Descripteur de forme)$2rasuqam 608 $aStatistiques (Descripteur de forme)$2rasuqam 608 $aPublications en se?rie.$2rvmgf 608 $aStatistiques.$2rvmgf 608 $aPublications officielles.$2rvmgf 615 0$aPower resources 615 6$aRessources e?nerge?tiques 615 7$aPower resources. 615 7$aApprovisionnement e?nerge?tique. 615 17$aConsommation d'e?nergie. 615 17$aProduction e?nerge?tique. 615 7$aIndicateur e?conomique. 615 17$aRessources e?nerge?tiques. 676 $a333.79/0971/021 712 02$aStatistique Canada.$bSection des indicateurs courants de l'investissement. 801 0$bNLC 801 1$bNLC 801 2$bOCLCQ 801 2$bUQ1 801 2$bOCLCQ 801 2$bHEBIS 801 2$bOCLCF 801 2$bOCLCO 801 2$bOCLCQ 801 2$bOCLCO 801 2$bOCLCQ 801 2$bNLC 801 2$bOCLCQ 801 2$bQ3C 801 2$bOCLCO 801 2$bOCL 801 2$bNLC 801 2$bOCLCL 801 2$bOCLCQ 906 $aJOURNAL 912 $a9910516102203321 996 $aGuide statistique de l'énergie$91916013 997 $aUNINA
