Deviation from the Normal Mode Expansion in a Coupled Graphene-Nanomechanical System
A significant deviation from the normal mode expansion is observed in the optomechanically measured thermal noise of a graphene membrane suspended on a...
Interpenetrating graphene networks: Three-dimensional node-line semimetals with massive negative linear compressibilities
We investigated the stability and mechanical and electronic properties of 15 metastable mixed sp2−sp3 carbon allotropes in the family of interpenetrating graphene networks...
Role of direct exchange and Dzyaloshinskii-Moriya interactions in magnetic properties of graphene derivatives: C_{2} F and C_{2} H
According to Lieb's theorem the ferromagnetic interaction in graphene-based materials with bipartite lattice is a result of disbalance between the number of sites...
Contact-Induced Spin Relaxation in Graphene Nonlocal Spin Valves
We report on a systematic study of contact-induced spin relaxation in gated graphene nonlocal spin valves. We demonstrate the enhancement of the nonlocal...
Entanglement bonanza
Quantum computers promise huge speedups on some computational problems because they harness a strange physical property called entanglement, in which...
Crossover to the anomalous quantum regime in the extrinsic spin Hall effect of graphene
Recent reports of spin-orbit coupling enhancement in chemically modified graphene have opened doors to studies of the spin Hall effect with massless chiral...
Scientists set traps for atoms with single-particle precision
Atoms, photons, and other quantum particles are often capricious and finicky by nature; very rarely at a standstill, they often...
Interaction-induced metallic state in graphene on hexagonal boron nitride
The Coulomb interaction is widely known to enhance the effective mass of interacting particles and therefore tends to favor a localized state at...
Self-Affine Graphene Metasurfaces for Tunable Broadband Absorption
Graphene has emerged as a promising platform for THz metasurfaces supporting electrically tunable deep-subwavelength plasmonic excitations. Here, we introduce a broadband graphene metasurface...
Origin and Magnitude of ‘Designer’ Spin-Orbit Interaction in Graphene on Semiconducting Transition Metal Dichalcogenides
In recent years, researchers have successfully produced an array of crystalline materials only one or a few atoms thick with nearly perfect structure....
Tuning the Optically Bright and Dark States of Doped Graphene Quantum Dots
Employing a combination of the many-body configuration-interaction method described by an extended Hubbard model and first-principles calculations, we predict the emergence of high...
Negative Kerr Nonlinearity of Graphene as seen via Chirped-Pulse-Pumped Self-Phase Modulation
We experimentally demonstrate a negative Kerr nonlinearity for quasiundoped graphene. Hereto, we introduce the method of chirped-pulse-pumped self-phase modulation and apply it to...
