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 switching of surface metallicity in 1T-TaSe2
Junde Liu, Liwen Su, Pei Liu +12
The surface of a quantum material provides a distinct electronic environment in which reconstruction can stabilize states absent from the bulk. However, whether light can persisten…
The role of non-equilibrium populations in dark exciton formation
Paul Werner, Wiebke Bennecke, Jan Philipp Bange +15
In two-dimensional transition metal dichalcogenide structures, the optical excitation of a bright exciton may be followed by the formation of a plethora of lower energy dark states…
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…
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…
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…
Time-resolved ARPES with probe energy of 6.0/7.2 eV and switchable resolution configuration
Mojun Pan, Junde Liu, Famin Chen +3
We present a detailed exposition of the design for time- and angle-resolved photoemission spectroscopy using a UV probe laser source that combines the nonlinear effects of \b{eta}-…
Removing grid structure in angle-resolved photoemission spectra via deep learning method
Junde Liu, Dongchen Huang, Yi-feng Yang +1
Spectroscopic data may often contain unwanted extrinsic signals. For example, in ARPES experiment, a wire mesh is typically placed in front of the CCD to block stray photo-electron…
Spectroscopic data de-noising via training-set-free deep learning method
Dongchen Huang, Junde Liu, Tian Qian +1
De-noising plays a crucial role in the post-processing of spectra. Machine learning-based methods show good performance in extracting intrinsic information from noisy data, but oft…
