Electrical tunability of terahertz nonlinearity in graphene
Sergey Kovalev, Hassan A. Hafez, Klaas-Jan Tielrooij +15
Graphene is conceivably the most nonlinear optoelectronic material. Its nonlinear optical coefficients in the terahertz (THz) frequency range surpass those of other materials by ma…

Enhanced Terahertz Photoresponse via Acoustic Plasmon Cavity Resonances in Scalable Graphene
Domenico De Fazio, Sebastián Castilla, Karuppasamy P. Soundarapandian +11
Precise control and nanoscale confinement of terahertz (THz) fields are essential requirements for emerging applications in photonics, quantum technologies, wireless communications…
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…
Nonreciprocal plasmons in one-dimensional carbon nanostructures
Álvaro Rodríguez Echarri, F. Javier García de Abajo, Joel D. Cox
The directional control of light in miniaturized plasmonic waveguides holds appealing possibilities for emerging nanophotonic technologies, but is hindered by the intrinsic recipro…
Signatures of Kondo-lattice behavior in the two-dimensional ferromagnet FeGeTe
Carmen Rubio-Verdú, Katharina J. Franke
FeGeTe is a paradigmatic van der Waals magnet with the full microscopic picture of magnetic interactions still under debate. Here, we use scanning tunneling microscopy and…
Phonon spectra, quantum geometry, and the Goldstone theorem
Guglielmo Pellitteri, Zenan Dai, Haoyu Hu +5
Phonons are essential quasi-particles of all crystals and play a key role in fundamental properties such as thermal transport and superconductivity. In particular, acoustic phonons…
Quantum Electrodynamics of graphene Landau levels in a deep-subwavelength hyperbolic phonon polariton cavity
Gian Marcello Andolina, Matteo Ceccanti, Bianca Turini +4
The confinement of electromagnetic radiation within extremely small volumes offers an effective means to significantly enhance light-matter interactions, to the extent that zero-po…
Topological Amplification of the Bosonic Kitaev Chain with Non-Uniform Loss
Clément Fortin, Kai Wang, T. Pereg-Barnea
The bosonic Kitaev chain is known to have extraordinary properties distinct from its fermionic counterpart. For example, it exhibits the non-Hermitian skin effect -- its eigenmodes…
Optical properties, plasmons, and orbital Skyrme textures in twisted TMDs
Lorenzo Cavicchi, Koen J. A. Reijnders, Mikhail I. Katsnelson +1
In the long-wavelength limit, Bloch-band Berry curvature has no effect on the bulk plasmons of a two-dimensional electron system. In this Letter we show instead that bulk plasmons…
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 optical…
Free-electron coupling to surface polaritons mediated by small scatterers
