Electrically-driven vibronic spectroscopy with sub-molecular resolution
Benjamin Doppagne, Michael C. Chong, Etienne Lorchat +6
A scanning tunneling microscope is used to generate the electroluminescence of phthalocyanine molecules deposited on NaCl/Ag(111). Photon spectra reveal an intense emission line at…
Electron backscattering in a cavity: ballistic and coherent effects
A. A. Kozikov, D. Weinmann, C. Rossler +4
Numerous experimental and theoretical studies have focused on low-dimensional systems locally perturbed by the biased tip of a scanning force microscope. In all cases either open o…
Topological collective plasmons in bipartite chains of metallic nanoparticles
Charles A. Downing, Guillaume Weick
We study a bipartite linear chain constituted by spherical metallic nanoparticles, where each nanoparticle supports a localized surface plasmon. The near-field dipolar interaction…
Spin-wave propagation in ultra-thin YIG based waveguides
M. Collet, O. Gladii, M. Evelt +9
Spin-wave propagation in an assembly of microfabricated 20 nm thick, 2.5 μm wide Yttrium Iron Garnet (YIG) waveguides is studied using propagating spin-wave spectroscopy (PSWS) and…
Nanohelices as superlattices: Bloch oscillations and electric dipole transitions
C. A. Downing, M. G. Robinson, M. E. Portnoi
Subjecting a nanohelix to a transverse electric field gives rise to superlattice behavior with tunable electronic properties. We theoretically investigate such a system and find Bl…
Massless Dirac fermions in two dimensions: Confinement in nonuniform magnetic fields
C. A. Downing, M. E. Portnoi
We show how it is possible to trap two-dimensional massless Dirac fermions in spatially inhomogeneous magnetic fields, as long as the formed magnetic quantum dot (or ring) is of a…
Phase space methods for the spin dynamics in condensed matter systems
Jerome Hurst, Paul-Antoine Hervieux, Giovanni Manfredi
Using the phase-space formulation of quantum mechanics, we derive a four-component Wigner equation for a system composed of spin-1/2 fermions (typically, electrons) including the Z…
From tunneling to contact in a magnetic atom: the non-equilibrium Kondo effect
Deung-Jang Choi, Paula Abufager, Laurent Limot +1
A low-temperature scanning tunneling microscope was employed to study the differential conductance in an atomic junction formed by an adsorbed Co atom on a Cu(100) surface and a co…
Kondo resonance of a Co atom exchange coupled to a ferromagnetic tip
D. -J. Choi, S. Guissart, M. Ormaza +4
The Kondo effect of a Co atom on Cu(100) was investigated with a low-temperature scanning tunneling microscope using a monoatomically sharp nickel tip. Upon a tip-Co contact, the d…
Monitoring Electrostatically-Induced Deflection, Strain and Doping in Suspended Graphene using Raman Spectroscopy
Dominik Metten, Guillaume Froehlicher, Stéphane Berciaud
Electrostatic gating offers elegant ways to simultaneously strain and dope atomically thin membranes. Here, we report on a detailed \textit{in situ} Raman scattering study on graph…
Magnetic quantum dots and rings in two dimensions
C. A. Downing, M. E. Portnoi
We consider the motion of electrons confined to a two dimensional plane with an externally applied perpendicular inhomogeneous magnetic field, both with and without a Coulomb poten…
Nonradiative limitations to plasmon propagation in chains of metallic nanoparticles
Adam Brandstetter-Kunc, Guillaume Weick, Charles A. Downing +2
We investigate the collective plasmonic modes in a chain of metallic nanoparticles that are coupled by near-field interactions. The size- and momentum-dependent nonradiative Landau…
Quantum atomistic approach for interacting spins
O. Morandi
The phenomenological Landau theory of the spin precession has been used to reproduce the out-of-equilibrium properties of many magnetic systems. However, such an approach suffers f…
Plasmon polaritons in cubic lattices of spherical metallic nanoparticles
Simon Lamowski, Charlie-Ray Mann, Felicitas Hellbach +3
We theoretically investigate plasmon polaritons in cubic lattices of spherical metallic nanoparticles. The nanoparticles, each supporting triply-degenerate localized surface plasmo…
High-harmonic generation in a quantum electron gas trapped in a nonparabolic and anisotropic well
Jerome Hurst, Kevin Leveque-Simon, Paul-Antoine Hervieux +2
An effective self-consistent model is derived and used to study the dynamics of an electron gas confined in a nonparabolic and anisotropic quantum well. This approach is based on t…
Classical origin of conductance oscillations in an integrable cavity
Christina Pöltl, Aleksey Kozikov, Klaus Ensslin +5
Scanning gate microscopy measurements in a circular ballistic cavity with a tip placed near its center yield a non-monotonic dependence of the conductance on the tip voltage. Detai…
Study of the ultrafast dynamics of ferromagnetic materials with a Quantum Monte Carlo atomistic model
O. Morandi, P. -A. Hervieux
We study of the ultrafast dynamics of the atomic angular momentum in ferrimagnets irradiated by laser pulses. My apply a quantum atomistic spin approach based on the Monte Carlo te…
Direct versus indirect band gap emission and exciton-exciton annihilation in atomically thin molybdenum ditelluride (MoTe)
Guillaume Froehlicher, Etienne Lorchat, Stéphane Berciaud
We probe the room temperature photoluminescence of -layer molybdenum ditelluride (MoTe) in the continuous wave (cw) regime. The photoluminescence quantum yield of monolayer…
