DOI: 10.1002/wsb.1549

Abstract: A variety of acoustic strategies have been implemented to disperse wildlife from areas of human‐wildlife conflict. Propane cannons are a popular tool; however, their efficacy based on avian behavior has yet to be fully explored.… read more here.

DOI: 10.1007/s00601-024-01942-0

Abstract: Strongly interacting systems appear in several areas of physics and are characterized by attractive interactions that can almost, or just barely, loosely bind two particles. Although this definition is made at the two-body level, this… read more here.

DOI: 10.1103/cwdt-dj6z

Abstract: The validity range of the time-honored effective range expansion can be very limited due to the presence of a left-hand cut close to the two-particle threshold. Such a left-hand cut arises in the two-particle interaction… read more here.

DOI: 10.1103/physreva.101.013605

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.

DOI: 10.1103/physreva.97.043613

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.111.034003

Abstract: We discuss various methods for determining the level shifts induced by short-range interactions in exotic atoms which are formed by a hadron and a nucleus of opposite charge. The energy shifts can be related to… 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.

DOI: 10.1103/physrevc.97.014301

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.
