Strongly-coupled hybrid lattice-plasmons in layered cuprates
Ke-Jun Xu, Nathan Giles-Donovan, Stefano Agrestini +11
Metallic systems with delocalized valence electrons host collective charge density oscillations known as plasmons. On the other hand, conventional insulators do not have free elect…

Contrasting electron-phonon interaction between electron- and hole-doped cuprates
Qinda Guo, Ke-Jun Xu, Magnus H. Berntsen +15
Spin- and charge-lattice interactions are potential key factors in the microscopic mechanism of high-temperature superconductivity in cuprates. Although both interactions can drama…

Flat bands and distinct density wave orders in correlated Kagome superconductor CsCrSb
Shuting Peng, Yulei Han, Yongkai Li +15
Kagome metal CsVSb has attracted much recent attention due to the coexistence of multiple exotic orders and the associated proposals to mimic unconventional high temperatur…
