Quantized vortex-core structure is theoretically investigated in fermion superfluids with population imbalance for two atom species of neutral atom clouds near a Feshbach resonance. In contrast with the vortex core in balance case where the quantum depletion makes a vortex visible through the density profile measurement, the vortex core is filled in and becomes less visible because the quantized discrete bound states are occupied exclusively by the majority species. Yet it is shown that the…

Visibility of Vortex Core in Fermionic Superfluid with Population Imbalance

Abstract In Fermionic superfluids with a vortex, at T=0, the depletion of the atomic density appears in the core region, which is strongly associated with the discreteness of the core-bound state,

FFLO and vortex states in superconductors with strong paramagnetic effect

In type-II superconductors (Fetter & Hohenberg, 1969), magnetic fields penetrate into superconductors as quantized flux lines with flux quanta φ0 = hc/2e, where h is Planck constant, c velocity of

Vortex states in superconductors with strong Pauli-paramagnetic effect

Using quasiclassical theory, we analyze the vortex structure of strong-paramagnetic superconductors. There, induced paramagnetic moments are accumulated exclusively around the vortex core. We

Spin-polarized vortices with reversed circulation

We present the analysis of the structure of vortices with the spin-polarized core from a weak coupling limit to the unitary regime of the BCS-BEC crossover. We show the mechanism for the generation

Rotating quantum turbulence in the unitary Fermi gas

Quantized vortices carry the angular momentum in rotating superfluids, and are key to the phenomenon of quantum turbulence. Advances in ultra-cold atom technology enable quantum turbulence to be

Universal aspects of vortex reconnections across the BCS-BEC crossover

Reconnecting vortices in a superfluid allow for the energy transfer between different length scales and its subsequent dissipation. Present picture assumes that the dynamics of a reconnection is

Symmetry Protected Topological Superfluids and Superconductors --- From the Basics to $^3$He ---

In this article, we give a comprehensive review of recent progress in research on symmetry-protected topological superfluids and topological crystalline superconductors, and their physical



Fermionic Superfluidity with Imbalanced Spin Populations

The superfluidity regime was established in a two-state mixture of ultracold fermionic atoms with imbalanced state populations and the quantum phase transition to the normal state was characterized, known as the Pauli limit of superfluidity.

Low-Lying Quasiparticle Excitations around a Vortex Core in Quantum Limit

Focusing on a quantum-limit behavior, we study a single vortex in a clean s-wave type-II superconductor by self-consistently solving the Bogoliubov-de Gennes equation. The discrete energy levels of

Structure of a quantized vortex near the BCS-BEC crossover in an atomic Fermi gas.

It is predicted that the matter density depletion and the discrete core levels are detectable in the vicinity of the BCS-Bose-Einstein condensation crossover point.

Microscopic structure of a vortex line in a dilute superfluid fermi gas.

Comparison of the numerical results with analytical expressions clearly indicates that the energy of the vortex is governed by the zero-temperature BCS coherence length.

Observation of Vortex Lattices in Bose-Einstein Condensates

The observation of dislocations, irregular structure, and dynamics indicates that gaseous Bose-Einstein condensates may be a model system for the study of vortex matter.

Generic phase diagram of Fermion superfluids with population imbalance.

It is shown by microscopic calculations for trapped imbalanced Fermi superfluids that the gap function always has sign changes, i.e., the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO)-like state, up to a

Strongly interacting Fermi gases with density imbalance.

It is shown how radio-frequency spectroscopy reflects the phase separation, and can provide direct evidence of the FFLO-type oscillations via observing the nodes of the order parameter.

Vortex state in a strongly coupled dilute atomic fermionic superfluid.

We show that in a dilute fermionic superfluid, when the fermions interact with an infinite scattering length, a vortex state is characterized by a strong density depletion along the vortex core. This

Relation between Vortex Core Charge and Vortex Bound States

Spatially inhomogeneous electron distribution around a single vortex is discussed on the basis of the Bogoliubov-de Gennes theory. The spatial structure and temperature dependence of the electron

Pairing and Phase Separation in a Polarized Fermi Gas

We report the observation of pairing in a gas of atomic fermions with unequal numbers of two components. Beyond a critical polarization, the gas separates into a phase that is consistent with a
