Abstract:In this talk we focus on the quantum many-body fermionic system. I will present several approximation results based on joint works with Xuwen Chen and Zhifei Zhang. We proved the zero temperature second order ground state energy approximation in the Gross-Pitaevskii regime corresponding to the famous Huang-Yang formula (1957). Based on this result , we also proved a HY type second order approximation to the thermodynamic pressure for positive temperature.
