Image polaritons in boron nitride for extreme polariton confinement with low losses
In-Ho Lee, Mingze He, Xi Zhang +8
Polaritons in two-dimensional materials provide extreme light confinement that is difficult to achieve with metal plasmonics. However, such tight confinement inevitably increases o…

Correlated Insulating States and Transport Signature of Superconductivity in Twisted Trilayer Graphene Moiré of Moiré Superlattices
Kan-Ting Tsai, Xi Zhang, Ziyan Zhu +5
Layers of two-dimensional materials stacked with a small twist-angle give rise to beating periodic patterns on a scale much larger than the original lattice, referred to as a moiré…
