The Schrödinger-Newton equations beyond Newton
Giovanni Manfredi
The scope of this paper is twofold. First, we derive rigorously a low-velocity and Galilei-covariant limit of the gravitoelectromagnetic (GEM) equations. Subsequently, these reduce…
Landau level spectroscopy of electron-electron interactions in graphene
C. Faugeras, S. Berciaud, P. Leszczynski +11
We present magneto-Raman scattering studies of electronic inter Landau level excitations in quasi-neutral graphene samples with different strengths of Coulomb interaction. The band…
Dirac plasmons in bipartite lattices of metallic nanoparticles
Thomas Jebb Sturges, Claire Woollacott, Guillaume Weick +1
We study theoretically "graphene-like" plasmonic metamaterials constituted by two-dimensional arrays of metallic nanoparticles, including perfect honeycomb structures with and with…
The 2014 Magnetism Roadmap
Robert L. Stamps, Stephan Breitkreutz, Johan Åkerman +11
Magnetism is a very fascinating and dynamic field. Especially in the last 30 years it has experienced many major advances in the full range from novel fundamental phenomena to new…
Voltage-controlled inversion of tunnel magnetoresistance in epitaxial Nickel/Graphene/MgO/Cobalt junctions
F. Godel, M. Venkata Kamalakar, B. Doudin +3
We report on the fabrication and characterization of vertical spin-valve structures using a thick epitaxial MgO barrier as spacer layer and a graphene-passivated Ni film as bottom…
Solid state plasmas
Giovanni Manfredi, Jérôme Hurst
Magnetic fusion devices operate at regimes characterized by extremely high temperatures and low densities, for which the charged particles motion is well described by classical mec…
Size calibration of strained epitaxial islands due to dipole-monopole interaction
Tokar V. I., Dreyssé H
Irreversible growth of strained epitaxial nanoislands has been studied with the use of the kinetic Monte Carlo (KMC) technique. It has been shown that the strain-inducing size misf…
Phase diagrams of one-dimensional half-filled two-orbital SU(N) cold fermions systems
V. Bois, S. Capponi, P. Lecheminant +2
We investigate possible realizations of exotic SU(N) symmetry-protected topological (SPT) phases with alkaline-earth cold fermionic atoms loaded into one-dimensional optical lattic…
Kondo effect in binuclear metal-organic complexes with weakly interacting spins
L. Zhang, A. Bagrets, D. Xenioti +10
We report a combined experimental and theoretical study of the Kondo effect in a series of binuclear metal-organic complexes of the form [(Me(hfacac)_2)_2(bpym)]^0, with Me = Nicke…
Cavity enhanced transport of excitons
Johannes Schachenmayer, Claudiu Genes, Edoardo Tignone +1
We show that exciton-type transport in certain materials can be dramatically modified by their inclusion in an optical cavity: the modification of the electromagnetic vacuum mode s…
Conductivity in organic semiconductors hybridized with the vacuum field
E. Orgiu, J. George, J. A. Hutchison +10
Organic semiconductors have generated considerable interest for their potential for creating inexpensive and flexible devices easily processed on a large scale [1-11]. However tech…
Spatial patterns of dissipative polariton solitons in semiconductor microcavities
J. K. Chana, M. Sich, F. Fras +9
Semiconductor microcavities operating in the polaritonic regime are highly non-linear, high speed systems due to the unique half-light, half-matter nature of polaritons. Here, we r…
Multistate nonvolatile straintronics controlled by a lateral electric field
V. Iurchuk, B. Doudin, B. Kundys
We present a multifunctional and multistate permanent memory device based on lateral electric field control of a strained surface. Sub-coercive electrical writing of a remnant stra…
Probing electronic excitations in mono- to pentalayer graphene by micro-magneto-Raman spectroscopy
Stéphane Berciaud, Marek Potemski, Clément Faugeras
We probe electronic excitations between Landau levels in freestanding layer graphene over a broad energy range, with unprecedented spectral and spatial resolution, using micro-…
Decay of dark and bright plasmonic modes in a metallic nanoparticle dimer
Adam Brandstetter-Kunc, Guillaume Weick, Dietmar Weinmann +1
We develop a general quantum theory of the coupled plasmonic modes resulting from the near-field interaction between localized surface plasmons in a heterogeneous metallic nanopart…
Two-dimensional Lattice Gauge Theories with Superconducting Quantum Circuits
D. Marcos, P. Widmer, E. Rico +4
A quantum simulator of U(1) lattice gauge theories can be implemented with superconducting circuits. This allows the investigation of confined and deconfined phases in quantum link…
All-Optical Blister Test of Suspended Graphene Using Micro-Raman Spectroscopy
Dominik Metten, François Federspiel, Michelangelo Romeo +1
We report a comprehensive micro-Raman study of a pressurized suspended graphene membrane that hermetically seals a circular pit, etched in a Si/SiO substrate. Placing the sampl…
Hybrid cavity mechanics with doped systems
Aurelien Dantan, Bhagya Nair, Guido Pupillo +1
We investigate the dynamics of a mechanical resonator in which is embedded an ensemble of two-level systems interacting with an optical cavity field. We show that this hybrid appro…
Parity-dependent localization in strongly coupled chains
Dietmar Weinmann, S. N. Evangelou
Anderson localization of wave-functions at zero energy in quasi-1D systems of disordered chains with inter-chain coupling is examined. Localization becomes weaker than for…
Transmissive optomechanical platforms with engineered spatial defects
Edoardo Tignone, Guido Pupillo, Claudiu Genes
We investigate the optomechanical photon-phonon coupling of a single light mode propagating through an array of vibrating mechanical elements. As recently shown for the particular…
