Building up on the familiar two-body physics, successively adding more and more atoms gives an intuitive picture of the many-body physics in the thermodynamic limit. The basic theoretical tools (Fock space, effective interactions, density matrices, and useful soluble models) are introduced in a pedagogical fashion, connecting the few- and many-body viewpoints. An in-depth discussion is devoted to the computational methods used (exact diagonalization and wave-packet dynamics), which are put into the context of common many-body methods, such as DMRG and Quantum Monte Carlo. The few-body picture is then applied to the study of one-dimensional trapped bosons, the main emphasis being on the crossover from weak interactions to the limit of infinite repulsion, where the bosons ''fermionize''.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838357454\"\u003e\u003ch3\u003eA few-body perspective\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838357454","offer_id":39498916528221,"sku":"9783838357454","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/2f81fc1b-9ae6-4fef-bdf4-c457a4894903.jpg?v=1773122560","url":"https:\/\/shop.autorenwelt.de\/products\/ultracold-bosons-in-one-dimension-von-sascha-zollner","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
