Bosonic and fermionic dipoles on a ring
Sascha Zöllner, G. M. Bruun, C. J. Pethick +1
We show that dipolar bosons and fermions confined in a quasi-one-dimensional ring trap exhibit a rich variety of states because their interaction is inhomogeneous. For purely repul…
Polarons and Molecules in a Two-Dimensional Fermi Gas
Sascha Zöllner, G. M. Bruun, C. J. Pethick
We study an impurity atom in a two-dimensional Fermi gas using variational wave functions for (i) an impurity dressed by particle-hole excitations (polaron) and (ii) a dimer consis…
Superfluid dynamics in neutron star crusts
C. J. Pethick, N. Chamel, S. Reddy
A simple description of superfluid hydrodynamics in the inner crust of a neutron star is given. Particular attention is paid to the effect of the lattice of nuclei on the propertie…
Constraints on neutron star radii based on chiral effective field theory interactions
K. Hebeler, J. M. Lattimer, C. J. Pethick +1
We show that microscopic calculations based on chiral effective field theory interactions constrain the properties of neutron-rich matter below nuclear densities to a much higher d…
Comment on "Normal phase of an imbalanced Fermi gas"
Zhenhua Yu, Sascha Zöllner, C. J. Pethick
Recently Mora and Chevy [Phys. Rev. Lett. 104, 230402 (2010), arXiv:1003.0213v2], in studying the energy of an atomic Fermi gas consisting of a majority species, 1, and a minority…
Clock shifts in a Fermi gas interacting with a minority component: a soluble model
G. M. Bruun, C. J. Pethick, Zhenhua Yu
We consider the absorption spectrum of a Fermi gas mixed with a minority species when majority fermions are transferred to another internal state by an external probe. In the limit…
