{ "item_title" : "Introduction to Statistical Field Theory", "item_author" : [" Edouard Brézin "], "item_description" : "Knowledge of the renormalization group and field theory is a key part of physics, and is essential in condensed matter and particle physics. Written for advanced undergraduate and beginning graduate students, this textbook provides a concise introduction to this subject. The textbook deals directly with the loop-expansion of the free-energy, also known as the background field method. This is a powerful method, especially when dealing with symmetries, and statistical mechanics. In focussing on free-energy, the author avoids long developments on field theory techniques. The necessity of renormalization then follows.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/0/52/119/303/0521193036_b.jpg", "price_data" : { "retail_price" : "116.00", "online_price" : "116.00", "our_price" : "116.00", "club_price" : "116.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
