Title: Anomalous quantum mass flow of atoms in p-wave resonance

Abstract

I analyze an atomic Fermi gas with a planar p-wave interaction, motivated by the experimentally observed anisotropy in p-wave Feshbach resonances. An axial superfluid state is verified. A domain wall object is discovered to be a new topological defect of this superfluid and an explicit solution has been found. Gapless quasiparticles appear as bound states on the wall, dispersing in the continuum of reduced dimensions. They are chiral, deeply related to fermion zero modes in quantum chromodynamics. The chirality of the superfluid is manifested by a persistent anomalous mass current of atoms in the ground state. This quantum phenomenon is a prediction for future experiments.

  • We present a theory for electron magnetic resonance in superconductors possessing strong spin-orbit coupling and a vector order parameter. The crystal-field energy breaks rotational symmetry and provides the ''weak link'' responsible for predicted longitudinal resonances and frequency shifts of transverse modes. Thin-film experiments to look for such resonances are discussed.
  • We present a theoretical study of the possibility of p-wave superfluidity in a gas of Fermi atoms with a p-wave Feshbach resonance. This anisotropic Feshbach resonance leads to a tunable pairing interaction in the p-wave Cooper channel. The character of superfluidity is shown to continuously change from the p-wave BCS type to the Bose-Einstein condensation (BEC) of tightly-bound molecules with finite orbital angular momenta, Lz={+-}1 and 0, as the threshold energy 2{nu} of the Feshbach resonance is lowered.
  • Most of the current theories on the p-wave superfluid in cold atomic gases are based on the effective-range theory for the two-body scattering, where the low-energy p-wave scattering amplitude f{sub 1}(k) is given by f{sub 1}(k)=-1/[ik+1/(Vk{sup 2})+1/R]. Here k is the incident momentum, V and R are the k-independent scattering volume and effective range, respectively. However, due to the long-range nature of the van der Waals interaction between two colliding ultracold atoms, the p-wave scattering amplitude of the two atoms is not described by the effective-range theory [J. Math. Phys. 4, 54 (1963); Phys. Rev. A 58, 4222 (1998)]. Inmore » this paper we provide an explicit calculation for the p-wave scattering of two ultracold atoms near the p-wave magnetic Feshbach resonance. We show that in this case the low-energy p-wave scattering amplitude f{sub 1}(k)=-1/[ik+1/(V{sup eff}k{sup 2})+1/(S{sup eff}k)+1/R{sup eff}] where V{sup eff}, S{sup eff}, and R{sup eff} are k-dependent parameters. Based on this result, we identify sufficient conditions for the effective-range theory to be a good approximation of the exact scattering amplitude. Using these conditions we show that the effective-range theory is a good approximation for the p-wave scattering in the ultracold gases of {sup 6}Li and {sup 40}K when the scattering volume is enhanced by the resonance.« less
  • Mercury isotopes are investigated with two-color resonance ionization mass spectroscopy (RIMS). Isotope shifts, hyperfine structure splittings, and the lifetime of the intermediate 6s6p {sup 3}P{sub 1} state are determined by RIMS. Ion yields at the threshold region in various static electric fields are measured in order to determine an extrapolated ionization energy value at zero field strength. New energy values for high-lying bound 6s nd {sup 3}D (21<n<70) Rydberg states of Hg isotopes are found under field-free conditions and with delayed, pulsed electric field ionization. To the author's knowledge this is the first time that isotopic effects on the ionizationmore » energy are deduced from the convergence limit of the Rydberg series.« less
