Two distinct exciton states observed in 2H stacked bilayer molybdenum diselenide
Excitons in a bilayer MoSe₂ semiconductor. Schematics depicting different types of excitonic complexes (i.e., electron–hole pairs bound by Coulomb forces) in a naturally stacked bilayer of the semiconductor MoSe₂. Red…
Implications for quantum computing and spintronics materials
Kobe University quantum solid state physicist FUSEYA Yuki proved that the surface of bismuth masks the fact that the bulk material is not “topological,” a property valuable for a material’s…
A new study provides insights into cleaning up noise in quantum entanglement
Researchers found that no universal entanglement purification protocol is guaranteed to improve fidelity of entangled states in all possible quantum systems. Credit: Zhong Lab Quantum entanglement—a connection between particles that…
Alternative approach offers low-cost, energy-efficient way to study light-matter interactions
Gaining insights into polariton dynamics. This image captures a laser beam interacting with polariton microcavities, revealing how polaritons help protect emitting materials from brightness loss. Credit: Mikael Nyberg Researchers at…
