Emergence of Chern Supermetal and Pair-Density Wave through Higher-Order Van Hove Singularities in the Haldane-Hubbard Model
Pedro Castro, Daniel Shaffer, Yi-Ming Wu +1
While advances in electronic band theory have brought to light new topological systems, understanding the interplay of band topology and electronic interactions remains a frontier…
Sublattice modulated superconductivity in the Kagome Hubbard model
Tilman Schwemmer, Hendrik Hohmann, Matteo Dürrnagel +8
We identify a superconducting order featuring spatial pair modulations on the kagome lattice subject to onsite Hubbard U and nearest neighbor V interactions. Within our functional…
Spectral properties of 1D extended Hubbard model from bosonization and time-dependent variational principle: applications to 1D cuprate
Hao-Xin Wang, Yi-Ming Wu, Yi-Fan Jiang +1
Recent ARPES experiments on doped 1D cuprates revealed the importance of effective near-neighbor (NN) attractions in explaining certain features in spectral functions. Here we inve…
Sublattice Interference promotes Pair Density Wave order in Kagome Metals
Yi-Ming Wu, Ronny Thomale, S. Raghu
Motivated by the observation of a pair density wave (PDW) in the kagome metal CsVSb, we consider the fate of electrons near a p-type van Hove singularity (vHS) in the p…
Pair density wave and loop current promoted by van Hove singularities in moiré systems
Zhengzhi Wu, Yi-ming Wu, Fengcheng Wu
We theoretically show that in the presence of conventional or higher order van Hove singularities(VHS), the bare finite momentum pairing, also known as the pair density wave (PDW),…
Odd frequency pairing in a quantum critical metal
Yi-Ming Wu, Shang-Shun Zhang, Artem Abanov +1
We analyze a possibility for odd-frequency pairing near a quantum critical point(QCP) in a metal. We consider a model with dynamical pairing interaction (the…
The Conditions for Pomeranchuk Instability in a Fermi Liquid
Yi-Ming Wu, Avraham Klein, Andrey V. Chubukov
We perform a microscropic analysis of how the constraints imposed by conservation laws affect Pomeranchuk instabilities in a Fermi liquid. The conventional view is that these…
Symmetry Protected and Topologically Protected Crossed Andreev Reflection
Yi-Ming Wu, Xiong-Jun Liu
Crossed Andreev reflection (CAR) is considered to probe the non-locality of the Majorana quasiparticles in topological superconductors. We propose here to study the CAR in multiban…
Symmetry Reduction and Boundary Modes for Fe-Chains on an s-wave Superconductor
Yu-Qin Chen, Yi-Ming Wu, Xiong-Jun Liu
We investigate the superconducting phase diagram and boundary modes for a quasi-1D system formed by three Fe-Chains on an s-wave superconductor, motivated by the recent Princeton e…
