At large temperature, when scaling =2c/N with some fixed constant c>0, in the large-N limit we observe a crossover from Ginibre's circular law or its generalisation to the density of non-interacting particles at =0. Using Ward identities and saddle point methods we derive a partial differential equation of generalised Liouville type for the crossover density. For radially symmetric potentials we present some asymptotic results and give examples for the numerical solution of the crossover density. These findings generalise previous results when the interacting particles are confined to the real line. In that situation we derive an integral equation for the resolvent valid for a general potential as well, and present the analytic solution for the density in the case of a Gaussian plus logarithmic potential.","lang":"eng"}],"volume":175,"page":"1043-1065","issue":"6","publication_identifier":{"issn":["0022-4715"],"eissn":["1572-9613"]},"user_id":"30615","type":"journal_article","publication_status":"published","publication":"JOURNAL OF STATISTICAL PHYSICS","_id":"2936333","quality_controlled":"1","doi":"10.1007/s10955-019-02276-6","title":"The High Temperature Crossover for General 2D Coulomb Gases","external_id":{"isi":["000471641000001"]},"author":[{"id":"23134650","last_name":"Akemann","first_name":"Gernot","full_name":"Akemann, Gernot"},{"first_name":"Sung-Soo","full_name":"Byun, Sung-Soo","last_name":"Byun"}]}]
