Local atomic configuration control of superconductivity in the undoped pnictide parent compound BaFe2As2
Jong-Hoon Kang, Philip J. Ryan, Jong-Woo Kim +13
Emergent superconductivity is strongly correlated with the symmetry of local atomic configuration in the parent compounds of iron-based superconductors. While chemical doping or hy…
Rotational anisotropy Raman spectrometer for high-sensitivity crystallographic symmetry analysis
Di Cheng, Junxiang Li, Shizhuo Luo +2
Raman spectroscopy stands as a cornerstone technique for probing collective excitations and emergent quantum phases in solids. While polarization-resolved Raman scattering has been…
Chirality manipulation of ultrafast phase switchings in a correlated CDW-Weyl semimetal
Bing Cheng, Di Cheng, Tao Jiang +8
A recently emerging concept for quantum phase discovery is the controlled gapping of linear band crossings in topological semimetals. For example, achieving topological superconduc…
Observation of the Magnonic Dicke Superradiant Phase Transition
Dasom Kim, Sohail Dasgupta, Xiaoxuan Ma +16
Two-level atoms coupled with single-mode cavity photons are predicted to exhibit a quantum phase transition when the coupling strength exceeds a critical value, entering a phase in…
Low-energy electrodynamics of infinite-layer nickelates: evidence for d-wave superconductivity in the dirty limit
Bing Cheng, Di Cheng, Kyuho Lee +9
The discovery of superconductivity in infinite-layer nickelates establishes a new category of unconventional superconductors that share structural and electronic similarities with…
Ultrafast cooperative electronic, structural, and magnetic switching in an altermagnet
Tiangao Lu, Ao Wu, Junxiang Li +5
Femtosecond laser control of antiferromagnetic order is a cornerstone for future memory and logic devices operating at terahertz clock rates. The advent of altermagnets -- antiferr…
Evidence for highly damped Higgs mode in infinite-layer nickelates
Bing Cheng, Di Cheng, Kyuho Lee +10
The dynamics of Higgs mode in superconductors, manifested as coherent oscillations of the superconducting order parameter amplitude, provides vital insights into the nature of the…
Revealing Fano Resonance in Dirac Materials ZrTe5 through Raman Scattering
Di Cheng, Tao Jiang, Feng Zhang +10
We explore the Fano resonance in ZrTe5, using Raman scattering measurements. We identified two closely spaced B2g phonon modes, B2g I and B2g II, around 9 meV and 10 meV, respectiv…
Optical signatures of noncentrosymmetric structural distortion in altermagnetic MnTe
Ao Wu, Di Cheng, Xinyun Wang +3
The hexagonal MnTe is a prime material candidate for altermagnets, an emerging class of magnetic compounds characterized by the nontrivial interplay of antiparallel spin arrangemen…
ControlEdit: A MultiModal Local Clothing Image Editing Method
Di Cheng, YingJie Shi, ShiXin Sun +3
Multimodal clothing image editing refers to the precise adjustment and modification of clothing images using data such as textual descriptions and visual images as control conditio…
