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…
Plasmon dynamics in graphene
Suheng Xu, Birui Yang, Nishchhal Verma +15
Plasmon are collective oscillations of mobile electrons with dynamics controlled by their charge stiffness("Drude weight"). Using terahertz spacetime metrology, we probe Plasmon dy…
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…
Sliding Disassembly of van der Waals Heterostructures
Jordan Pack, Karl V. Falb, Sanat Ghosh +13
Many recent advances in our understanding of two-dimensional (2D) electron systems stem from van der Waals (vdW) heterostructures. The assembly process relies on the weak bonding a…
Supersonic flow and hydraulic jump in an electronic de Laval nozzle
Johannes Geurs, Tatiana A. Webb, Yinjie Guo +10
In very clean solid-state systems, where carrier-carrier interactions dominate over any other scattering mechanisms, the flow of electrons can be described within a hydrodynamic fr…
Dynamic Interfacial Quantum Dipoles in Charge Transfer Heterostructures

Hysteretic gate responses of two-dimensional material heterostructures serve as sensitive probes of the underlying electronic states and hold significant promise for the developmen…
Imaging strain-controlled magnetic reversal in thin CrSBr
Kousik Bagani, Andriani Vervelaki, Daniel Jetter +9
Two-dimensional materials are extraordinarily sensitive to external stimuli, making them ideal for studying fundamental properties and for engineering devices with new functionalit…
Uniaxial plasmon polaritons charge transfer at the graphene/CrSBr interface
Daniel J. Rizzo, Eric Seewald, Fangzhou Zhao +24
Graphene is a privileged 2D platform for hosting confined light-matter excitations known as surface plasmon-polaritons (SPPs), as it possesses low intrinsic losses with a high degr…
