Third order corrections to the ground state energy of the gas of spin fermions with arbitrary densities of different spin projections
Piotr H. Chankowski, Jacek Wojtkiewicz, Szymon Augustynowicz
Recently we have computed the third order corrections to the ground state energy of the arbitrarily polarized diluted gas of spin 1/2 fermions interacting through a spin-independen…
Third order corrections to the ground state energy of the polarized diluted gas of spin fermions
Piotr H. Chankowski, Jacek Wojtkiewicz, Rashad Bakhshizada
We present the results of the computation of the third order corrections to the ground state energy of the diluted polarized gas of nonrelativistic spin fermions interacting…
On the ground-state energy of a mixture of two different oppositely polarized fermionic gases
Piotr Chankowski, Jacek Wojtkiewicz
We report the results of the computation of the order correction, where is the Fermi wave vector and the -wave scattering length of th…
Ground state energy of the polarized diluted gas of interacting spin fermions
Piotr Chankowski, Jacek Wojtkiewicz
The effective field theory approach simplifies the perturbative computation of the ground state energy of the diluted gas of fermions allowing in the case of the unpolarized system…
