Charge order through crystallization of Frenkel excitons: realization in kagome metals
Ruoshi Jiang, Bartomeu Monserrat, Wei Ku
Charge order is a widely observed and representative example of spontaneous broken symmetries in quantum states of matter. Owing to the large intra-atomic Coulomb energy, the charg…
Ultrafast anisotropic exciton transport in phosphorene
Kai-Wei Chang, Joshua J. P. Thompson, Bartomeu Monserrat
Phosphorene is a two-dimensional (2D) material exhibiting strong in-plane structural anisotropy. In this work, we investigate the influence of structural anisotropy on the optics,…
Discovery of High-Temperature Charge Order and Time-Reversal Symmetry-Breaking in the Kagome Superconductor YRu3Si2
P. Kràl, J. N. Graham, V. Sazgari +21
The identification of high-temperature unconventional charge order and superconductivity in kagome quantum materials is pivotal for deepening our understanding of geometrically fru…
Impact of electronic correlations on the superconductivity of high-pressure CeH
Siyu Chen, Yao Wei, Bartomeu Monserrat +2
Rare-earth superhydrides have attracted considerable attention because of their high critical superconducting temperature under extreme pressures. They are known to have localized…
Band-Gap Tunability in Anharmonic Perovskite-like Semiconductors Driven by Polar Electron-Phonon Coupling
Pol Benítez, Ruoshi Jiang, Siyu Chen +5
The ability to finely tune optoelectronic properties in semiconductors is crucial for the development of advanced technologies, ranging from photodetectors to photovoltaics. In thi…
Pressure-induced trans-proximate correlation in LaNiO and possible routes to enhance its superconductivity
Ruoshi Jiang, Zhiyu Fan, Bartomeu Monserrat +1
We report an unexpected trans-proximate interlayer correlation (stronger correlation between disjoint layers than the adjacent ones) in the high-pressure phase of the recently disc…
