三维稀费米气体的Bogoliubov理论
Bogoliubov theory for the dilute Fermi gas in three dimensions
摘要：
在一个自旋为1/2的N个费米子的三维稀体系中，研究了由基态能量与非相互作用费米子海态能量之差给出的关联能.我们回顾了Falconi等人的论文[Ann. Henri Poincaré 22（2021），2283-2353]中的一些最新结果，其中我们利用了Bogoliubov理论可以有效描述的系统低能激发的几乎玻色子性质。
英文摘要：
In a dilute system of N fermions with spin 1/2 in three dimensions, we study the correlation energy which is given by the difference between the ground state energy and the energy of the non-interacting Fermi sea state. We review some recent results from the paper by Falconi et al. [Ann. Henri Poincaré 22 (2021), 2283-2353], where we make use of the almost-bosonic nature of the low-energy excitations of the system which can be effectively described by Bogoliubov theory.
