Vortex-bound solitons in topological superfluid He
J. T. Mäkinen, K. Zhang, V. B. Eltsov
The different superfluid phases of He are described by -wave order parameters that include anisotropy axes both in the orbital and spin spaces. The anisotropy axes character…
Fibration, Nexus and Cosmological Composite Topological Defects in Uniaxially Disordered Superfluid He
Kuang Zhang
The composited cosmological defects in superfluids of nafen-disorded 3He are discussed in this review article. In spite of the existence of the half quantum vortices (Alice strings…
String monopoles, string walls, vortex-skyrmions and nexus objects in polar distorted B-phase of He
G. E. Volovik, K. Zhang
The composite cosmological objects -- Kibble-Lazarides-Shafi (KLS) walls bounded by strings and cosmic strings terminated by Nambu monopoles -- could be produced during the phase t…
Quantum phases of a two-dimensional polarized degenerate Fermi gas in an optical cavity
Yanlin Feng, Kuang Zhang, Jingtao Fan +3
In this paper we analytically investigate the ground-state properties of a two-dimensional polarized degenerate Fermi gas in a high-finesse optical cavity, which is governed by a g…
Lifshitz transitions, type-II Dirac and Weyl fermions, event horizon and all that
Kuang Zhang, G. E. Volovik
The type-II Weyl and type-II Dirac points emerge in semimetals and also in relativistic systems. In particular, the type-II Weyl fermions may emerge behind the event horizon of bla…
Spin-orbit coupled repulsive Fermi atoms in a one-dimensional optical lattice
Xiaofan Zhou, Kuang Zhang, Junjun Liang +2
Motivated by recent experimental development, we investigate spin-orbit coupled repulsive Fermi atoms in a one-dimensional optical lattice. Using the density-matrix renormalization…
SU(2) Ginzburg-Landau theory for degenerate Fermi gases with synthetic non-Abelian gauge fields
Kuang Zhang, Yanlin Feng, Chuanwei Zhang +2
The non-Abelian gauge fields play a key role in achieving novel quantum phenomena in condensed-matter and high-energy physics. Recently, the synthetic non-Abelian gauge fields have…
Unconventional pairings of spin-orbit coupled attractive degenerate Fermi gas in a one dimensional optical lattice
Junjun Liang, Xiaofan Zhou, Pak Hong Chui +5
Understanding novel pairings in attractive degenerate Fermi gases is crucial for exploring rich superfluid physics. In this report, we reveal unconventional pairings induced by spi…
Spin-orbit-induced bound state and molecular signature of the degenerate Fermi gas in a narrow Feshbach resonance
Kuang Zhang, Gang Chen, Suotang Jia
In this paper we explore the spin-orbit-induced bound state and molecular signature of the degenerate Fermi gas in a narrow Feshbach resonance based on a generalized two-channel mo…
