The excitonic insulator (EI) is an exotic ground state of narrow-gap semiconductors and semimetals arising from spontaneous condensation electron-hole pairs bound by attractive Coulomb interaction. Despite research on EIs dating back to half a century ago, their existence in real materials remains subject ongoing debate. In this study, through systematic experimental theoretical investigations, we provide evidence for the EI van der Waals compound <a:math...
Most existing image inpainting methods aim to fill in the missing content inside-hole region of target image. However, areas be restored realistically degraded images are unspecified. Previous studies have failed recover degradations due absence explicit mask indication. Meanwhile, inconsistent patterns blended complexly with content. Therefore, estimating whether certain pixels out distribution and considering object is consistent context necessary. Motivated by these observations, a...
High-order harmonic generation (HHG) has a broad spectrum covering vacuum ultraviolet to extreme (XUV) bands, which is useful for applications involving material analyses at different information depths. Such an HHG light source perfect time- and angle-resolved photoemission spectroscopy. Here, we demonstrate high-photon flux driven by two-color field. Applying fused silica compression stage reduce the driving pulse width, obtained high XUV photon of 2 × 1012 phs/s @21.6 eV on target. We...
Time-resolved and angle-resolved photoemission spectroscopy (trARPES) is a powerful method to detect the non-equilibrium electronic structure in solid systems. In this study, we report trARPES apparatus with tunable photon energy selectively among 12, 16.8, 21.6 eV at repetition rate of 400 kHz. The temporal resolutions three harmonics are determined as 104/111/157 meV 276/190/154 fs, respectively. flux on sample estimated be 1010–1011 photons/s by using photodiode. Finally, performance...
We present a detailed exposition of the design for time- and angle-resolved photoemission spectroscopy using UV probe laser source that combines nonlinear effects β-BaB2O4 KBe2BO3F2 optical crystals. The photon energy can be switched between 6.0 7.2 eV, with flexibility to operate each setting under two distinct resolution configurations. Under fully optimized configuration, we achieve an 8.5 meV at eV 10 eV. Alternatively, switching other configuration enhances temporal resolution, yielding...
Spectroscopic data may often contain unwanted extrinsic signals. For example, in the angle-resolved photoemission spectroscopy (ARPES) experiment, a wire mesh is typically placed front of charge-coupled device to block stray photoelectrons but could cause gridlike structure spectra during quick measurement mode. In past, this was removed using mathematical Fourier filtering method by erasing periodic structure. However, lead information loss and vacancies because grid not strictly linearly...
Abstract The search for topological superconductivity (TSC) is currently an exciting pursuit, since non-trivial superconducting phases could host exotic Majorana modes. However, the difficulty in fabricating proximity-induced TSC heterostructures, sensitivity to disorder and stringent restrictions of intrinsic place serious limitations formidable challenges on materials related applications. Here, we report a new type TSC, namely surface (IS-TSC) demonstrate it layered AuSn 4 with T c 2.4 K....

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 training set that may be typically expensive real experimental measurements. Unsupervised algorithms slow many iterations to achieve convergence. Here, we bridge this gap by proposing training-set-free two-stage deep method. We show fuzzy fixed input previous can improved introducing an adaptive prior. Combined with more...
