Curvature-driven revival of charge density waves in non-Euclidean space
Zhipeng Song, Zeyu Liu, Junde Liu +12
Strongly correlated quantum states, such as charge density waves (CDWs), are exquisitely sensitive to Fermi surface topology and lattice symmetry, and are typically quenched by hea…
Nonvolatile optical control of interlayer stacking order in 1T-TaS2
Junde Liu, Pei Liu, Liu Yang +19
Nonvolatile optical manipulation of material properties on demand is a highly sought-after feature in the advancement of future optoelectronic applications. While the discovery of…
Evidence for an Excitonic Insulator State in TaPdTe
Jierui Huang, Bei Jiang, Jingyu Yao +30
The excitonic insulator (EI) is an exotic ground state of narrow-gap semiconductors and semimetals arising from spontaneous condensation of electron-hole pairs bound by attractive…
Training-set-free two-stage deep learning for spectroscopic data de-noising
Dongchen Huang, Junde Liu, Tian Qian +1
De-noising is a prominent step in the spectra post-processing procedure. Previous machine learning-based methods are fast but mostly based on supervised learning and require a trai…
