Driven-dissipative superconductivity in moiré heterostructure without attraction
Tsung-Sheng Huang, Atac Imamoglu, Mohammad Hafezi +1
The paper proposes a driven‑dissipative protocol that creates a stationary superconducting state in a two‑dimensional bilayer moiré heterostructure by using optically induced pseud…
Probing Quantum Anomalous Hall States in Twisted Bilayer WSe2 via Attractive Polaron Spectroscopy
Beini Gao, Mahdi Ghafariasl, Mahmoud Jalali Mehrabad +15
Moiré superlattices in semiconductors exhibit a rich variety of interaction-induced topological states, including quantum anomalous Hall (QAH) effects. A recent study hinted that…
Giant enhancement of exciton diffusion near an electronic Mott insulator
Pranshoo Upadhyay, Daniel G. Suárez-Forero, Tsung-Sheng Huang +9
Bose-Fermi mixtures naturally appear in various physical systems. In semiconductor heterostructures, such mixtures can be realized, with bosons as excitons and fermions as dopant c…
Optical engineering and detection of magnetism in moiré semiconductors
Tsung-Sheng Huang, Andrey Grankin, Yu-Xin Wang +1
We present a general framework for optically inducing, controlling, and probing spin states in moiré systems. In particular, we demonstrate that applying Raman optical drives to m…
Collective optical properties of moiré excitons
Tsung-Sheng Huang, Yu-Xin Wang, Yan-Qi Wang +3
We propose that excitons in moiré transition metal dichalcogenide bilayers offer a promising platform for investigating collective radiative properties. While some of these optica…
