Fractional Chern insulator edges: crystalline effects and optical measurements
Yan-Qi Wang, Johannes Motruk, Andrey Grankin +1
Edge states of chiral topologically ordered phases are commonly described by chiral Luttinger liquids, effective theories that are exact only in the hydrodynamic limit. Motivated b…
Quantum Metamorphosis: Programmable Emergence and the Breakdown of Bulk-Edge Dichotomy in Multiscale Systems
Mahmoud Jalali Mehrabad, Alireza Parhizkar, Lida Xu +6
Multiscale synergy -- the interplay of a system's distinct characteristic length, time, and energy scales -- is becoming a unifying thread across many contemporary branches of scie…
Multi-timescale frequency-phase matching for high-yield nonlinear photonics
Mahmoud Jalali Mehrabad, Lida Xu, Gregory Moille +9
Integrated nonlinear photonic technologies, even with state-of-the-art fabrication with only a few nanometer geometry variations, face significant challenges in achieving wafer-sca…
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 mo…
Roadmap for Photonics with 2D Materials
F. Javier García de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
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 t…
Purely electronic model for exciton-polaron formation in moiré heterostructures
Fabian Pichler, Mohammad Hafezi, Michael Knap
Understanding interactions between excitons and correlated electronic states presents a fundamental challenge in quantum many-body physics. Here, we introduce a purely electronic m…
On-chip multi-timescale spatiotemporal optical synchronization
Lida Xu, Mahmoud Jalali Mehrabad, Christopher J. Flower +7
Mode-locking mechanisms are key resources in nonlinear optical phenomena, such as micro-ring solitonic states, and have transformed metrology, precision spectroscopy, and optical c…
Enhanced Cooper pairing in nano-patterned metals
Masoud Mohammadi-Arzanagh, Andrey Grankin, Victor Galitski +1
Nano-patterning has been shown to be a powerful tool for manipulating the vibrational modes of elastic structures, with applications such as optical-mechanical mode coupling. Inspi…
