Quantum materials QED with van der Waals crystals
Suheng Xu, Brian Vermilyea, Ran Jing +19
A central goal of the emerging field of materials QED is to harness subwavelength electromagnetic confinement in engineered cavities to tailor light-matter interactions. Here, we d…
Signatures of quantum chaos in phonon-polariton billiards
Yinan Dong, Felix Liu, Ekrem Demirboga +11
We use scanning near-field optical microscopy to image hyperbolic phonon polaritons in hexagonal boron nitride (hBN) billiards with integrable and chaotic geometries. In Sinai bill…
Electrically driven plasmon-polaritonic bistability in Dirac electron tunneling transistors
Shuai Zhang, Yang Xu, Junhe Zhang +12
Bistability-two distinct stable states under identical parameter-is not only a fundamental physical concept but also of importance in practical applications. While plasmon-polarito…
Ultrafast Charge-Doping via Photo-Thermionic Injection in van der Waals Devices
Yiliu Li, Esteban Rojas-Gatjens, Yinjie Guo +10
Van der Waals (vdW) heterostructures of two-dimensional (2D) materials have become a rich playground for the exploration of correlated quantum phases, and recent studies have begun…
Photoinduced Metal-to-Insulator Transitions in 2D Moiré Devices
Yiliu Li, Esteban Rojas-Gatjens, Yinjie Guo +10
Photoexcitation has been utilized to control quantum matter and to uncover metastable phases far from equilibrium. Among demonstrations to date, the most common is the photo-induce…
Dynamic Interfacial Quantum Dipoles in Charge Transfer Heterostructures
Ziyu Liu, Emil Viñas Boström, Dihao Sun +7
Hysteretic gate responses of two-dimensional material heterostructures serve as sensitive probes of the underlying electronic states and hold significant promise for the developmen…
Flat band excitons in a three-dimensional supertwisted spiral transition metal dichalcogenide
Yinan Dong, Yuzhou Zhao, Lennart Klebl +19
A new frontier in van der Waals twistronics is the development of three-dimensional (3D) supertwisted materials, where each successive atomic layer rotates by the same angle. While…
Low-Energy Electronic Structure in the Unconventional Charge-Ordered State of ScVSn
Asish K. Kundu, Xiong Huang, Eric Seewald +15
Kagome vanadates {\it A}VSb display unusual low-temperature electronic properties including charge density waves (CDW), whose microscopic origin remains unsettled. Recently…
Electron spin resonance and collective excitations in magic-angle twisted bilayer graphene
Erin Morissette, Jiang-Xiazi Lin, Dihao Sun +11
In a strongly correlated system, collective excitations contain key information regarding the electronic order of the underlying ground state. An abundance of collective modes in t…
Quench Dynamics of Josephson Current in a Topological Josephson Junction
Dihao Sun, Jie Liu
The Josephson Effect is a distinguishing feature of a topological Josephson junction. However, stringent conditions make it hard to observe in experiments. Here we numerically…
