Electron decoherence in cylindrical holes and circular apertures
Cruz I. Velasco, F. Javier Garc\'ıa de Abajo
The coherence of free electrons sets fundamental limits on the resolution and contrast of phase-sensitive electron microscopy because coherence is lost whenever the electron leaves…
Plasmon-Enhanced Second-Harmonic Generation in Atomically Thin Crystalline Silver Nanostructures
Saad Abdullah, Philipp K. Jenke, Andrew P. Weber +8
The intrinsically weak nonlinear optical response of existing materials, further constrained by symmetry-forbidden second-order processes in centrosymmetric media, severely limits…
Thermal vacuum friction of objects with different dimensionality
Gor Chalyan, F. Javier García de Abajo
Radiative forces acting on neutral bodies moving through a thermal bath represent a unique manifestation of the interplay between relativistic kinematics and thermal fluctuations.…
Nonlinear photoluminescence in gold thin films
A. Rodríguez Echarri, F. Iyikanat, S. Boroviks +3
Promising applications in photonics are driven by the ability to fabricate crystal-quality metal thin films of controlled thickness down to a few nanometers. In particular, these m…
Simultaneous imaging of dopants and free charge carriers by STEM-EELS
Hongbin Yang, Andrea Konečná, Xianghan Xu +4
Doping inhomogeneities in solids are not uncommon, but their microscopic observation and understanding are limited due to the lack of bulk-sensitive experimental techniques with hi…
Atomic Floquet physics revealed by free electrons
Eduardo Arqué López, Valerio Di Giulio, F. Javier García de Abajo
We theoretically investigate the ability of free electrons to yield information on the nonlinear Floquet dynamics of atomic systems subject to intense external illumination. By app…
Imaging the Renner-Teller effect using laser-induced electron diffraction
Kasra Amini, Michele Sclafani, Tobias Steinle +18
Structural information on electronically excited neutral molecules can be indirectly retrieved, largely through pump-probe and rotational spectroscopy measurements with the aid of…
Magnetically Activated Rotational Vacuum Friction
Deng Pan, Hongxing Xu, F. Javier García de Abajo
We predict the existence of a torque acting on an isotropic neutral nanosphere activated by a static magnetic field when the particle temperature differs from the surrounding vacuu…
Second-order quantum nonlinear optical processes in single graphene nanostructures and arrays
Marco T. Manzoni, Iván Silveiro, F. Javier García de Abajo +1
Intense efforts have been made in recent years to realize nonlinear optical interactions at the single-photon level. Much of this work has focused on achieving strong third-order n…
Surface plasmons at the interface between graphene and kerr-type nonlinear medium
Lei Wang, Wei Cai, Xinzheng Zhang +2
The properties of surface plasmons localized at the interface between graphene and kerr-type nonlinear medium in three dimensions are investigated. Compared with surface plasmons a…
Graphene plasmonics: A platform for strong light-matter interaction
Frank H. L. Koppens, Darrick E. Chang, F. Javier Garcia de Abajo
Graphene plasmons provide a suitable alternative to noble-metal plasmons because they exhibit much larger confinement and relatively long propagation distances, with the advantage…
Diffractive arrays of gold nanoparticles near an interface: critical role of the substrate
Baptiste Auguié, Xesús M. Bendaña, William L. Barnes +1
The optical properties of periodic arrays of plasmonic nanoantennas are strongly affected by coherent multiple scattering in the plane of the array, which leads to sharp spectral r…
