Role of Phase Fluctuation in Dynamic Competition Between Charge Order and Superconductivity in Cuprates
Mingu Kang, Pavel E. Dolgirev, Chao C. Zhang +9
Phase fluctuations are a key factor distinguishing nonthermal (ultrafast) and thermal phase transitions. Charge order in cuprates is characterized by short-range coherence while co…
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…
Symmetry-protected electronic metastability in an optically driven cuprate ladder
Hari Padma, Filippo Glerean, Sophia F. R. TenHuisen +23
Optically excited quantum materials exhibit nonequilibrium states with remarkable emergent properties, but these phenomena are usually transient, decaying on picosecond timescales…
Beyond-Hubbard pairing in a cuprate ladder
Hari Padma, Jinu Thomas, Sophia TenHuisen +13
The Hubbard model is believed to capture the essential physics of cuprate superconductors. However, recent theoretical studies suggest that it fails to reproduce a robust and homog…
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…
