Multi-gap topology and non-Abelian braiding of phonons from first principles
Bo Peng, Adrien Bouhon, Robert-Jan Slager +1
Non-Abelian states of matter, in which the final state depends on the order of the interchanges of two quasiparticles, can encode information immune from environmental noise with t…
Phonons as a platform for non-Abelian braiding and its manifestation in layered silicates
Bo Peng, Adrien Bouhon, Bartomeu Monserrat +1
Topological phases of matter have revolutionised the fundamental understanding of band theory and hold great promise for next-generation technologies such as low-power electronics…
Twist-angle engineering of excitonic quantum interference and optical nonlinearities in stacked 2D semiconductors
Kai-Qiang Lin, Paulo E. Faria Junior, Jonas M. Bauer +6
Twist-engineering of the electronic structure of van-der-Waals layered materials relies predominantly on band hybridization between layers. Band-edge states in transition-metal-dic…
Large-scale mapping of moiré superlattices by Raman imaging of interlayer breathing mode and moiré phonons
Kai-Qiang Lin, Johannes Holler, Jonas M. Bauer +6
Moiré superlattices can induce correlated-electronic phases in twisted van-der-Waals materials. Strongly correlated quantum phenomena emerge, such as superconductivity and the Mott…
Phonon-assisted electronic states modulation of few-layer PdSe2 at terahertz frequencies
Ziqi Li, Bo Peng, Miao-Ling Lin +6
Information technology demands high-speed optoelectronic devices, but going beyond the one terahertz (THz) barrier is challenging due to the difficulties associated with generating…
Bright excitons with negative-mass electrons
Kai-Qiang Lin, Chin Shen Ong, Sebastian Bange +15
Bound electron-hole excitonic states are generally not expected to form with charges of negative effective mass. We identify such excitons in a single layer of the semiconductor WS…
Room Temperature Continuous-wave Excited Biexciton Emission in CsPbBr3 Nanocrystals
Jie Chen, Qing Zhang, Wenna Du +13
Biexcitons are a manifestation of many-body excitonic interactions crucial for quantum information and quantum computation in the construction of coherent combinations of quantum s…
