A composite electron-lattice order: electronic nematicity of 2DEG and polarization density waves at a near-ferroelectric interface
Fei Yang, Zhi-Yang Wang, Long-Qing Chen
We consider a two-dimensional electron gas (2DEG) formed at a near-ferroelectric interface and strongly coupled to polar phonons. Through a self-consistent microscopic many-body ca…

Emergent spin-resolved electronic density waves from strong -wave altermagnetism and pseudogap phenomena from phason fluctuations
Fei Yang, Guo-Dong Zhao, Binghai Yan +1
Metallic -wave altermagnets provide a unique setting in which strong spin-momentum locking can qualitatively reshape electronic instabilities. Here we develop a self-consistent…
