Corrections to Local Density Approximation for superfluid trapped fermionic atoms from the Wigner-Kirkwood expansion

Peter Schuck, Michael Urban, Xavier Viñas

A semiclassical second-order differential equation for the inhomogeneous local gap is derived from a strict second-order expansion of the anomalous pairing tensor an…

Energy and Angle Dependence of Neutrino Scattering Rates in Proto-Neutron Star and Supernova Matter within Skyrme RPA

Mingya Duan, Michael Urban

Supernova explosions are the most powerful neutrino sources. The neutrino emission is also the dominating cooling mechanism for a proto-neutron star, whose interior is mainly compo…

Equation of state of superfluid neutron matter with low-momentum interactions

Viswanathan Palaniappan, S. Ramanan, Michael Urban

In this work, we calculate the ground state energy of pure neutron matter using the renormalization group based low-momentum effective interaction in Bogoliubov…

Low-momentum interactions for ultracold Fermi gases

M. Urban, S. Ramanan

We consider a two-component Fermi gas with a contact interaction from the BCS regime to the unitary limit. Starting from the idea that many-body effects should not depend on short-…

BCS-BEC Crossover Effects and Pseudogap in Neutron Matter

David Durel, Michael Urban

Due to the large neutron-neutron scattering length, dilute neutron matter resembles the unitary Fermi gas, which lies half-way in the crossover from the BCS phase of weakly coupled…

Pairing in pure neutron matter

S. Ramanan, M. Urban

We review the long standing problem of superfluid pairing in pure neutron matter. For the -wave pairing, we summarize the state of the art of many-body approaches including diff…
