Self-consistent GW theory for superconductivity in SrTiO3 models
Zhi-Hao Cui, John Sous, Andrew J. Millis +1
Superconductivity in doped SrTiO occurs over a wide range of carrier densities, including those for which the Fermi energy is below the polar longitudinal optical phonon scale.…
Tunable Narrowband Terahertz Radiation from van der Waals Ferroelectrics
Chun-Ying Huang, Taketo Handa, Daniel G. Chica +10
The terahertz (THz) spectral range is central to high-speed communication, precision metrology, sensing technologies, and a range of fundamental scientific investigations. Achievin…
Charge Density Wave and Ferromagnetism in Intercalated CrSBr
Margalit L. Feuer, Morgan Thinel, Xiong Huang +25
In materials with one-dimensional electronic bands, electron-electron interactions can produce intriguing quantum phenomena, including spin-charge separation and charge density wav…
Theory of interaction-induced charge order in CrSBr
Zhi-Hao Cui, Andrew J. Millis, David R. Reichman
CrSBr is a layered van der Waals insulator with a quasi one-dimensional electronic structure and in-plane ferromagnetic order. Recent experimental work on Li-doped CrSBr reveals qu…
Coupling of Electronic Transitions to Ferroelectric Order in a 2D Semiconductor
Chun-Ying Huang, Daniel G. Chica, Zhi-Hao Cui +16
A ferroelectric material often exhibits a soft transvers optical (TO) phonon mode which governs it phase transition. Charge coupling to this ferroelectric soft mode may further med…
