Origin of Spin Stripes in Bilayer Nickelate LaNiO
Hao-Xin Wang, Hanbit Oh, Tobias Helbig +7
The bilayer nickelate LaNiO has recently emerged as a high-temperature superconductor with unusual spin stripe order in its ambient pressure phase. We propose a microsc…
Superconductivity and magnetism in bilayer nickelates: itinerant perspective
Yi-Ming Wu, Tobias Helbig, Salahudin V. SmailagiÄ +4
We study superconductivity and magnetism in bilayer nickelates from an itinerant perspective. Starting from a tight binding fit to recent ARPES measurements on compressively strain…
A "negative" route to pair density wave order
Hao-Xin Wang, Yi-Jian Hu, Wen Huang +1
Pair density waves (PDW) are novel forms of superconducting states that exhibit periodically modulated pairing. A remaining challenge is to elucidate how intrinsic PDW order can em…
Pair-density-wave phase of strongly interacting electrons on the triangular lattice: A variational Monte Carlo study
Jiucai Wang, Wen Sun, Hao-Xin Wang +3
A robust theory of the mechanism of pair density wave (PDW) superconductivity (i.e. where Cooper pairs have nonzero center of mass momentum) remains elusive. Here we explore the tr…
Topological Magnetic Phases and Magnon-Phonon Hybridization in the Presence of Strong Dzyaloshinskii-Moriya Interaction
Weicen Dong, Haoxin Wang, Matteo Baggioli +1
In recent years, the interplay between quantum magnetism and topology has attracted growing interest, both for its fundamental importance and its technological potential. Topologic…
Robust d-wave superconductivity from the Su-Schrieffer-Heeger-Hubbard model: possible route to high-temperature superconductivity
Hao-Xin Wang, Yi-Fan Jiang, Hong Yao
Increasing numerical studies showed that the simplest Hubbard model on the square lattice with strong repulsion may not exhibit high-temperature superconductivity (SC). It is desir…
