Temperature dependence of Fano resonances in CrPS4
The Journal of Chemical Physics, 2022A Fano resonance, as often observed in scattering, absorption, or transmission experiments, arises from quantum interference between a discrete optical transition and a continuous background. Here, we present a temperature-dependent study on Fano resonances observed in photoluminescence from flakes of the layered semiconductor antiferromagnet chromium ...

Physical Review Letters, 2005
Recent advances in the generation of sub-fs extreme ultraviolet pulses and attosecond metrology have opened up the possibility to trace the time evolution of electronic wave packets inside atoms in pump-probe experiments. We investigate the feasibility of observing the buildup of a Fano resonance in the time domain by attosecond streaking techniques. A

Fano-chain: the Fano resonances in a nanoparticles chain
Journal of Modern Optics, 2012We show that for a linear chain of nanoparticles the Fano resonances can be excited and tuned through particle number manipulation by adding or removing particles from the chain. Fano modes excited in the chain, the spectrally overlapped bright superradiant and dark subradiant modes, are presented with current flow pictures for the first time, which ...

The resonances with asymmetric Fano line-shapes were originally discovered in the context of quantum mechanics (U. Fano, Phys. Rev., 124, 1866–1878, 1961). Quantum Fano resonances were generated from destructive interference of a discrete state with a continuum one.

Fano Resonance in Single‐Molecule Junctions
Angewandte Chemie, 2022AbstractThe Fano resonance in single‐molecule junctions could be created by interaction with discrete and continuous molecular orbitals and enables effective electron transport modulation between constructive and destructive interference within a small energy range.

Perspectives on the Fano Resonance Formula
Physica Scripta, 2004Summary: The general profile of a resonance, as given by Fano in 1961 is well known throughout physics. This comment provides some of the simplest derivations of this formula, together with a discussion of subtleties in handling continuum states with regard to their normalization, orthogonality, and completeness.

Nonlinear Fano-Resonant Dielectric Metasurfaces
Nano Letters, 2015Strong nonlinear light-matter interaction is highly sought-after for a variety of applications including lasing and all-optical light modulation. Recently, resonant plasmonic structures have been considered promising candidates for enhancing nonlinear optical processes due to their ability to greatly enhance the optical near-field; however, their small

Fano resonances in bilayer phosphorene nanoring
Nanotechnology, 2018Abstract Tunable transport properties and Fano resonances are predicted in a circular bilayer phosphorene nanoring. The conductance exhibits Fano resonances with varying incident energy and applied perpendicular magnetic field. These Fano resonance peaks can be accurately fitted with the well known Fano curves.

Terahertz tunable graphene Fano resonance
Nanotechnology, 2016By depositing graphene circular double rings (DR) on a SiO2/Si/polymer substrate, the tunable Fano resonance has been theoretically investigated in the terahertz regime, including the effects of the graphene Fermi level, structural parameters and operation frequency.

The Friedel sum rule at Fano resonances
Journal of Physics: Condensed Matter, 2009If a mesoscopic system is non-chaotic or non-ergodic then the thermodynamic and transport properties do not depend on the impurity averaged density of states. We show that the partial density of states as well as the density of states of a given system with a given impurity configuration can be determined exactly from the asymptotic wavefunction (or ...
