{"product_id":"entanglement-between-noncomplementary-parts-of-many-body-systems-von-hannu-christian-wichterich","title":"Entanglement Between Noncomplementary Parts of Many-Body Systems","description":"This thesis investigates the structure and behaviour of entanglement, the purely quantum mechanical part of correlations, in many-body systems, employing both numerical and analytical techniques at the interface of condensed matter theory and quantum information theory. Entanglement can be seen as a precious resource which, for example, enables the noiseless and instant transmission of quantum information, provided the communicating parties share a sufficient \"amount\" of it. Furthermore, measures of entanglement of a quantum mechanical state are perceived as useful probes of collective properties of many-body systems. For instance, certain measures are capable of detecting and classifying ground-state phases and, particularly, transition (or critical) points separating such phases. Chapters 2 and 3 focus on entanglement in many-body systems and its use as a potential resource for communication protocols. They address the questions of how a substantial amount of entanglement can be established between distant subsystems, and how efficiently this entanglement could be \"harvested\" by way of measurements. The subsequent chapters 4 and 5 are devoted to universality of entanglement between large collections of particles undergoing a quantum phase transition, where, despite the enormous complexity of these systems, collective properties including entanglement no longer depend crucially on the microscopic details.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783642268298\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783642193415\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783642268298","offer_id":39443182944349,"sku":"9783642268298","price":106.99,"currency_code":"EUR","in_stock":true},{"title":"Hardcover - 9783642193415","offer_id":39629589610589,"sku":"9783642193415","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/8e3ebb68-9465-4ed7-a322-249bda2e92b4.jpg?v=1775192620","url":"https:\/\/shop.autorenwelt.de\/products\/entanglement-between-noncomplementary-parts-of-many-body-systems-von-hannu-christian-wichterich","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
