Microscopic theory for electron-phonon coupling in twisted bilayer graphene
Ziyan Zhu, Thomas P. Devereaux
The origin of superconductivity in twisted bilayer graphene -- whether phonon-driven or electron-driven -- remains unresolved, in part due to the absence of a quantitative and effi…
Competition between charge-density-wave and superconducting orders on eight-leg square Hubbard cylinders
Hong-Chen Jiang, Thomas P. Devereaux, Steven A. Kivelson
The issue of whether -wave superconductivity (SC) occurs in the square-lattice Hubbard model with of order of the bandwidth has been one of the most debated issues to emerge…
Effects of the Next-Nearest-Neighbor Hopping on the Low-Dimensional Hubbard Model: Ferromagnetism, Antiferromagnetism, and Superconductivity
Luhang Yang, Adrian E. Feiguin, Thomas P. Devereaux +1
The Hubbard model has attracted considerable interest due to its prototypical role in describing strongly interacting electronic systems, such as high-critical-temperature supercon…
Hund's coupling assisted orbital-selective superconductivity in Ba1-xKxFe2As2
Elena Corbae, Rong Zhang, Cong Li +10
While the superconducting transition temperature of hole-doped Ba_{1-x}K_{x}Fe_{2}As_{2} decreases past optimal doping, superconductivity does not completely disappear even for the…
Non-monotonic band flattening near the magic angle of twisted bilayer MoTe
Yujun Deng, William Holtzmann, Ziyan Zhu +13
Twisted bilayer MoTe (tMoTe) is an emergent platform for exploring exotic quantum phases driven by the interplay between nontrivial band topology and strong electron correl…
Electronic structure of compressively strained thin film LaPrNiO
Bai Yang Wang, Yong Zhong, Sebastien Abadi +16
The discovery of superconductivity in the bulk nickelates under high pressure is a major advance in physics. The recent observation of superconductivity at ambient pressure in comp…
