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…
Terahertz photogalvanics in twisted bilayer graphene close to the second magic angle
M. Otteneder, S. Hubmann, X. Lu +6
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…
Multiple Flat Bands and Topological Hofstadter Butterfly in Twisted Bilayer Graphene Close to the Second Magic Angle
Xiaobo Lu, Biao Lian, Gaurav Chaudhary +8
Moiré superlattices in two-dimensional (2D) van der Waals (vdW) heterostructures provide 20 an efficient way to engineer electron band properties. The recent discovery of exotic qu…
Fermionic Chern insulator from twisted light with linear polarization
Utso Bhattacharya, Swati Chaudhary, Tobias Grass +3
The breaking of time-reversal symmetry is a crucial ingredient to topological bands. It can occur intrisically in materials with magnetic order, or be induced by external fields, s…
Harnessing Ultraconfined Graphene Plasmons to Probe the Electrodynamics of Superconductors
A. T. Costa, P. A. D. Gonçalves, D. N. Basov +3
We show that the Higgs mode of a superconductor, which is usually challenging to observe by far-field optics, can be made clearly visible using near-field optics by harnessing ultr…
Fractional angular momentum and anyon statistics of impurities in Laughlin liquids
Tobias Graß, Bruno Juliá-Díaz, Niccolò Baldelli +2
The elementary excitations of a fractional quantum Hall liquid are quasiparticles or quasiholes which are neither bosons nor fermions, but so-called anyons. Here we study impurity…
Fabry-Pérot oscillations in correlated carbon nanotubes
W. Yang, C. Urgell, S. L. De Bonis +3
We report the observation of an intriguing behaviour in the transport properties of nanodevices operating in a regime between the Fabry-Pérot and the Kondo limits. Using ultra-high…
Measuring topological invariants in polaritonic graphene
P. St-Jean, A. Dauphin, P. Massignan +10
Topological materials rely on engineering global properties of their bulk energy bands called topological invariants. These invariants, usually defined over the entire Brillouin zo…
Bulk detection of time-dependent topological transitions in quenched chiral models
Alessio D'Errico, Francesco Di Colandrea, Raouf Barboza +5
The topology of one-dimensional chiral systems is captured by the winding number of the Hamiltonian eigenstates. Here we show that this invariant can be read-out by measuring the m…
