Starting from a strong dominant magnetic field where the spin system is in a paramagnetic regime, we switch on a spin coupling susceptible of creating correlations responsible for the ferromagnetism order. We use the large coordination expansion method to study two cases: the adiabatic switching that monitors the evolution of the ground state until it reaches the quantum transition to ordered states; a sudden sweep (quench) that monitors instead the wave behavior of the quantum fluctuations and simulate the generation of off-site correlations.", "revisions": [ { "version": "v1", "updated": "2016-03-14T20:48:39.000Z" } ], "analyses": { "keywords": [ "quantum ising model", "quantum fluctuations", "wave propagation", "large coordination expansion method", "strong dominant magnetic field" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160304465N" } } }
