Exceptional horns in -root graphene and Lieb photonic ring lattices
A. M. Marques, D. Viedma, V. Ahufinger +1
We present a systematic construction of non-Hermitian tight-binding lattices whose Bloch spectra are th roots of those of Hermitian parent two-dimensional (2D) lattices, namely…
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…
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…
Quantum Kinetic Uncertainty Relations in Mesoscopic Conductors at Strong Coupling
Gianmichele Blasi, Ricard Ravell Rodríguez, Mykhailo Moskalets +2
Kinetic Uncertainty Relations (KURs) set fundamental limits on the precision of nonequilibrium transport by bounding the signal-to-noise ratio of currents in terms of the dynamical…
Shuttling Majorana zero modes in disordered and noisy topological superconductors
Bill P. Truong, Kartiek Agarwal, T. Pereg-Barnea
The braiding of Majorana zero modes (MZMs) forms the fundamental building block for topological quantum computation. Braiding protocols which involve the physical exchange of MZMs…
Roadmap on Nonlocality in Photonic Materials and Metamaterials
Francesco Monticone, N. Asger Mortensen, Antonio I. Fernández-Domínguez +63
Photonic technologies continue to drive the quest for new optical materials with unprecedented responses. A major frontier in this field is the exploration of nonlocal (spatially d…
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…
Direct detection of down-converted photons spontaneously produced at a single Josephson junction
Dorian Fraudet, Izak Snyman, Denis M. Basko +7
We study spontaneous photon decay into multiple photons triggered by strong non-linearities in a superconducting quantum simulator of the boundary sine-Gordon impurity model. Previ…
Depth mapping of metallic nanowire polymer nanocomposites by scanning dielectric microscopy
H. Balakrishnan, R. Millan-Solsona, M. Checa +3
Polymer nanocomposite materials based on metallic nanowires are widely investigated as transparent and flexible electrodes or as stretchable conductors and dielectrics for biosensi…
Optical response of noble metal nanostructures: Quantum surface effects in crystallographic facets
A. Rodríguez Echarri, P. A. D. Gonçalves, C. Tserkezis +3
Noble metal nanostructures are ubiquitous elements in nano-optics, supporting plasmon modes that can focus light down to length scales commensurate with nonlocal effects associated…
Ultra-fast calorimetric measurements of the electronic heat capacity of graphene
Mohammed Ali Aamir, John N. Moore, Xiaobo Lu +4
Heat capacity is an invaluable quantity in condensed matter physics, yet it has been so far experimentally inaccessible in two-dimensional (2D) van der Waals (vdW) materials, owing…

We report on the observation of photogalvanic effects in twisted bilayer graphene (tBLG) with a twist angle of 0.6°. We show that excitation of tBLG bulk causes a photocurrent, who…
Anomalous thermodiffusion of electrons in graphene
Deng Pan, Hongxing Xu, F. Javier García de Abajo
We reveal a dramatic departure of electron thermodiffusion in solids relative to the commonly accepted picture of the ideal free-electron gas model. In particular, we show that the…
