Chemical and optical control of chiral-domain dynamics in 1T-TaS
Qingzheng Qiu, Mengxian Zhao, Roman Mankowsky +14
Optical control of symmetry-breaking quantum phases is often constrained when one domain is strongly favored in equilibrium. This limitation is exemplified by the chiral charge-den…
Mixed spin states for robust ferromagnetism in strained SrCoO thin films
Xiquan Zheng, Nicholas B. Brookes, Flora Yakhou-Harris +11
Epitaxial strain in transition-metal oxides can induce dramatic changes in electronic and magnetic properties. A recent study on the epitaxially strained SrCoO thin films revea…
Ultrafast Orbital-Selective Photodoping Melts Charge Order in Overdoped Bi-based Cuprates
Xinyi Jiang, Qizhi Li, Qingzheng Qiu +10
High-temperature superconductivity in cuprates remains one of the enduring puzzles of condensed matter physics, with charge order (CO) playing a central yet elusive role, particula…
Photo-generated charge-transfer excitons in NiO revealed by ultrafast time-resolved resonant inelastic x-ray scattering
Giacomo Merzoni, Leonardo Martinelli, Sergii Parchenko +32
Strong electronic correlation can lead to insulating behavior and to the opening of large optical gaps, even in materials with partly filled valence shells. Although the non-equili…
Photo-induced Dynamics and Momentum Distribution of Chiral Charge Density Waves in 1T-TiSe
Qingzheng Qiu, Sae Hwan Chun, Jaeku Park +14
Exploring the photoinduced dynamics of chiral states offers promising avenues for advanced control of condensed matter systems. Photoinduced or photoenhanced chirality in 1T-TiSe$_…
Van-Hove annihilation and nematic instability on a Kagome lattice
Yu-Xiao Jiang, Sen Shao, Wei Xia +20
Novel states of matter arise in quantum materials due to strong interactions among electrons. A nematic phase breaks the point group symmetry of the crystal lattice and is known to…
Using magnetic dynamics to measure the spin gap in a candidate Kitaev material
Xinyi Jiang, Qingzheng Qiu, Cheng Peng +16
Materials potentially hosting Kitaev spin-liquid states are considered crucial for realizing topological quantum computing. However, the intricate nature of spin interactions withi…
Observation of giant circular dichroism induced by electronic chirality
Qian Xiao, Oleg Janson, Sonia Francoual +8
Chiral phases of matter, characterized by a definite handedness, abound in nature, ranging from the crystal structure of quartz to spiraling spin states in helical magnets. In …
Charge redistribution, charge order and plasmon in LaSrCuO/LaCuO superlattices
Qizhi Li, Lele Ju, Hsiaoyu Huang +11
Interfacial superconductors have the potential to revolutionize electronics, quantum computing, and fundamental physics due to their enhanced superconducting properties and ability…
Pressure-induced color change in the lutetium dihydride LuH2
Pengfei Shan, Ningning Wang, Xiquan Zheng +3
The lutetium dihydride LuH2 is stable at ambient conditions. Here we show that its color undergoes sequential changes from dark blue at ambient pressure to pink at ~2.2 GPa and the…
Absence of localized electrons in KTaO interface superconductors
Xinqiang Cai, Jungho Kim, Leonardo Martinelli +19
Recently, an exciting discovery of orientation-dependent superconductivity was made in two-dimensional electron gas (2DEG) at the interfaces of LaAlO/KTaO (LAO/KTO) or EuO/…
Prevailing charge order in overdoped cuprates beyond the superconducting dome
Qizhi Li, Hsiao-Yu Huang, Tianshuang Ren +14
The extremely overdoped cuprates are generally considered to be Fermi liquid metals without exotic orders, whereas the underdoped cuprates harbor intertwined states. Contrary to th…
Collective Radiance of Giant Atoms in Non-Markovian Regime
Qing-Yang Qiu, Ying Wu, Xin-You Lü
We investigate the non-Markovian dynamics of two giant artificial atoms interacting with a continuum of bosonic modes in a one-dimensional (1D) waveguide. Based on the diagrammatic…
