{"product_id":"path-integrals-biru-tsegaye-9783639343113","title":"Path Integrals","description":"A basic exposition of path integrals, an elegant and powerful technique in relation to non-relativistic quantum mechanics and statistical mechanics, is presented. Some exact propagators are calculated. Several statistical mechanics problems are discussed via a path integral formulation of the statistical density matrix and an application to second quantized Hamiltonians using coherent states is presented. The variational technique is considered with illustrative examples. Some selected recent achievements of the technique are reviewed. The effectiveness of this technique enhances with the evaluation of each new propagator. Central to this presentation have been Gaussian path integrals. The technique of general coordinate transformation and time rescaling is proving to be very valuable as it is even able to deal with originally non integrable problems.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Biru Tsegaye\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3639343115\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783639343113\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/10\/2011\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 116\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.40lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.28d","brand":"Biru Tsegaye","offers":[{"title":"Paperback","offer_id":47419620196607,"sku":"9783639343113","price":52.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_bad9be53-8cd2-48b0-8564-b06788ec1356.jpg?v=1761512753","url":"https:\/\/www.whiterainbookhouse.com\/products\/path-integrals-biru-tsegaye-9783639343113","provider":"WR Book House","version":"1.0","type":"link"}
