Nuclear response for the Skyrme effective interaction with zero range tensor terms (2009)
Davesne, D., Martini, M., Bennaceur, K., Meyer, J.
The effects of a zero-range tensor component of the effective interaction on nuclear response functions are determined in the so-called RPA approach. Explicit formula in the case of symmetric...
Collective modes of trapped Fermi gases with in-medium interaction (2008)
Chiacchiera, S., Lepers, T., Urban, M., Davesne, D.
Due to Pauli blocking of intermediate states, the scattering matrix (or $T$ matrix) of two fermionic atoms in a Fermi gas becomes different from that of two atoms in free space. This effect becomes...
How to preserve symmetries with cut-off regularized integrals? (2007)
Varin, T., Davesne, D., Oertel, M., Urban, M.
We present a prescription to calculate the quadratic and logarithmic divergent parts of several integrals employing a cutoff in a coherent way, i.e. in total agreement with symmetry requirements. As...
Power law in a gauge-invariant cut-off regularisation (2007)
Varin, T., Welzel, J., Deandrea, A., Davesne, D.
