Abstract: We theoretically investigate the thermodynamic properties of a strongly correlated two-dimensional Fermi gas with a confinement-induced negative effective range of interactions, which is described by a two-channel model Hamiltonian. By extending the many-body T-matrix approach… read more here.

Abstract: We theoretically investigate the effects of pairing fluctuations in an ultracold Fermi gas near a Feshbach resonance with a negative effective range. By employing a many-body T-matrix theory with a coupled boson-fermion model, we show… read more here.

DOI: 10.1103/physrevc.96.025809
Abstract: A new algorithm for the asymptotic nuclear coefficients calculation, which we call the $\Delta$-method, is proved and developed. This method was proposed in Ref. [O. L. Ramirez Suarez and J.-M. Sparenberg, arXiv: 1602.04082 [nucl-th] (2016)]… read more here.

Abstract: The thermodynamical ground-state properties and static response in both cold atoms at or close to unitarity and neutron matter are determined using a recently proposed Density Functional Theory (DFT) based on the s-wave scattering length… read more here.

DOI: 10.1103/physrevc.98.015803
Abstract: Recently a new $\Delta$-method for the calculation of asymptotic normalization coefficients (ANC) from phase-shift data has been formulated, proved and used for bound states. This method differs from the conventional one by fitting only the… read more here.

DOI: 10.1140/epjd/s10053-021-00083-x
Abstract: Elastic cross sections for electron scattering on tetrafluoromethane (CF $$_4$$ ) from 0 up to 5 eV energy are analyzed using semi-analytical approach to the modified effective range theory (MERT). It is shown that energy… read more here.
