I finished this work with my supervisor Prof.Semenoff and Dr.Karczmarek. We worked on Gross-Witten model in Large N gauge theory under ¿t Hooft limit. I focus on the k-representation of the SU(N) gauge group in 2- dimensional lattice, where k means the number of quarks. Our goal is to further understand quark confinement in Large N Quantum Chromodynamics(QCD) model. Prof. Semenoff derived the Action for the k-symmetric representation using the Saddle-Point Approximation. I further derived the Action of the k-exterior representation and we found an interesting phase transition from de-confined phase to confined phase when the number k changes. In Gross-Witten model, there is a phase transition as the coupling constant changes. In our study, both the coupling constant and the k-number give the whole phase transition diagram.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783846555569\"\u003e\u003ch3\u003ePhase Transition of k-strings on 2D lattice\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783846555569","offer_id":39494492520541,"sku":"9783846555569","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/0ebc1046-4e42-499f-a2eb-3bf3b30362fd.jpg?v=1757913470","url":"https:\/\/shop.autorenwelt.de\/en\/products\/large-n-gauge-theory-and-k-strings-von-shuhang-yang","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
