Deletion-contraction properties of graphically stable spaces
Andy Xiaoan Yang
Graphically stable spaces parametrize marked nodal curves whose permitted collisions of markings are determined by a graph. We study intersection num…
Quantum phase-field model: vortices and THz-induced gap dynamics in superconductors
R. Y. Fang, F. Yang, S. L. Zhang +1
The ability to simulate the spatial and temporal ordering dynamics of quantum phases in inhomogeneous systems, particularly in the low-temperature regime, is crucial for understand…
A Self-Consistent Computational Framework for Displacive Ferroelectrics from the Condensed Ground State
F. Yang, L. Q. Chen
Quantitative description of finite-temperature properties of displacive ferroelectrics, and in particular the critical behavior, is of fundamental importance to both theory and dev…
Hidden Crossover and Relaxor-Like Response from Emerging Polar Skyrmion Correlations in Ferroelectric Superlattices
Zhiyang Wang, Fei Yang, Long-Qing Chen
Polar skyrmions in ferroelectric superlattices are nanoscale topological polarization textures typically regarded as weakly coupled objects confined to individual layers, with a ro…
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 charge density waves and pseudogap phenomena from strong -wave altermagnetism
Fei Yang, Guo-Dong Zhao, Binghai Yan +1
Inspired by recent discovery of metallic -wave altermagnetism in KVSeO, we develop a self-consistent microscopic many-body calculation of density-wave order for an itine…
