The success of metal-based plasmonics for manipulating light at the nanoscale has been empowered by imaginative designs and advanced nano-fabrication. However, the fundamental optical and electronic properties of elemental metals, the prevailing plasmonic media, are difficult to alter using external stimuli. This limitation is particularly restrictive in applications that require modification o...

Label free tracking of small bio-particles such as proteins or viruses is great utility in the study biological processes, however experiments are frequently hindered by weak signal strengths and a susceptibility to scattering impurities. To overcome these problems we here propose novel technique leveraging enhanced sensitivity both interferometric detection strong field confinement surface pla...

We propose nanoscale magnetometry via isolated single-spin qubits as a probe of superconductivity in two-dimensional materials. characterize the magnetic field noise at qubit location, arising from current and spin fluctuations sample leading to measurable polarization decay qubit. show that due transverse studied function temperature sample-probe distance can be used extract useful information...

in this paper, the interaction between an oscillating dipole moment and a silver nanoparticle has been studied. our calculations are based on mie scattering theory and discrete dipole approximation(dda) method.at first, the resonance frequency due to excitingthe localized surface plasmons has been obtained using mie scattering theory and then by exciting a dipole moment in theclose proximity of...

Plasmon excitations in graphene, silicene, and germanene are studied using linear-response time-dependent density functional theory within the random phase approximation (RPA). In this work, we examine both plasmon dispersion behavior lifetime of extrinsic intrinsic plasmons for these three materials. For plasmons, found that their properties closely related to Landau damping. region without si...
