Topological Superconductivity in Two-Dimensional Altermagnetic Metals
Di Zhu, Zheng-Yang Zhuang, Zhigang Wu +1
Bringing magnetic metals into superconducting states represents an important approach for realizing unconventional superconductors and potentially even topological superconductors.…
Intrinsic Anomalous Hall Effect in a Bosonic Chiral Superfluid
Guan-Hua Huang, Zhi-Fang Xu, Zhigang Wu
The anomalous Hall effect has had a profound influence on the understanding of many electronic topological materials but is much less studied in their bosonic counterparts. We pred…
Observing Quantum Synchronization of a Single Trapped-Ion Qubit
Liyun Zhang, Zhao Wang, Yucheng Wang +4
Synchronizing a few-level quantum system is of fundamental importance to understanding synchronization in deep quantum regime. Whether a two-level system, the smallest quantum syst…
Higher first Chern numbers in one dimensional Bose-Fermi mixtures
Kristian Knakkergaard Nielsen, Zhigang Wu, Georg M. Bruun
We propose to use a one-dimensional system consisting of identical fermions in a periodically driven lattice immersed in a Bose gas, to realise topological superfluid phases with C…
Emergent Symmetry at Superradiance Transition of a Bose Condensate in Two Crossed Beam Cavities
Zhigang Wu, Yu Chen, Hui Zhai
Recently the ETH group has reported an experiment on superradiant transition of a Bose condensate in two crossed beam cavities. The surprise is that they find that across the super…
Time-reversal invariant topological superfluids in Bose-Fermi mixtures
Jonatan Melkær Midtgaard, Zhigang Wu, G. M. Bruun
A mixed dimensional system of fermions in two layers immersed in a Bose-Einstein condensate (BEC) is shown to be a promising setup to realise topological superfluids with time-reve…
Long range mediated interactions in a mixed dimensional system
Daniel Suchet, Zhigang Wu, Frédéric Chevy +1
We present a mixed-dimensional atomic gas system to unambiguously detect and systematically probe mediated interactions. In our scheme, fermionic atoms are confined in two parallel…
Topological superfluidity of lattice fermions inside a Bose-Einstein condensate
Jonatan Melkær Midtgaard, Zhigang Wu, G. M. Bruun
We calculate the phase diagram of identical fermions in a 2-dimensional (2D) lattice immersed in a 3D Bose-Einstein condensate (BEC). The fermions exchange density fluctuations in…
Topological superfluid in a Fermi-Bose mixture with a high critical temperature
Zhigang Wu, Georg M. Bruun
We show that a two-dimensional (2D) spin-polarised Fermi gas immersed in a 3D Bose-Einstein condensate (BEC) constitutes a very promising system to realise a superfluid.…
Liquid crystal phases of two-dimensional dipolar gases and Berezinskii-Kosterlitz-Thouless melting
Zhigang Wu, Jens K. Block, Georg M. Bruun
Liquid crystals are phases of matter intermediate between crystals and liquids. Whereas classical liquid crystals have been known for a long time and are used in electro-optical di…
Coexistence of density wave and superfluid order in a dipolar Fermi gas
Zhigang Wu, Jens K. Block, Georg M. Bruun
We analyse the coexistence of superfluid and density wave (stripe) order in a quasi-two-dimensional gas of dipolar fermions aligned by an external field. Remarkably, the anisotropi…
Probing the optical conductivity of trapped charge-neutral quantum gases
Zhigang Wu, Edward Taylor, Eugene Zaremba
We study a harmonically confined atomic gas which is subjected to an additional external potential such as an optical lattice. Using a linear response formulation, we determine the…
Mean-field yrast spectrum of a two-component Bose gas in ring geometry: persistent currents at higher angular momentum
Zhigang Wu, Eugene Zaremba
We use analytic soliton solutions of a two-component Bose gas in ring geometry to analyze the mean-field yrast spectrum of the system. We find that the spectrum exhibits a surprisi…
Persistent currents in a bosonic mixture in the ring geometry

In this paper we analyze the possibility of persistent currents of a two-species bosonic mixture in the one-dimensional ring geometry. We extend the arguments used by Bloch to obta…

Z. Wu, E. Zaremba
We study the dissipation of the centre of mass oscillation of a harmonically confined condensate in the presence of a disorder potential. An extension of the Generalized Harmonic T…

K. P. Driver, R. E. Cohen, Zhigang Wu +5
Silica is an abundant component of the Earth whose crystalline polymorphs play key roles in its structure and dynamics. As the simplest silicates, understanding pure silica is a pr…
