Frequency-Dependent Current Noise through Quantum-Dot Spin Valves

, 2006
We study frequency-dependent current noise through a single-level quantum dot connected to ferromagnetic leads with non-collinear magnetization. We propose to use the frequency-dependent Fano factor as a tool to detect single-spin dynamics in the quantum

Modulation-free laser frequency stabilization via balanced detection of common-path Fano resonance in all-PM fiber cavity

APL Photonics
Laser frequency stabilization is indispensable for extensive applications involving precision measurements, and the best performance has been achieved with the Pound–Drever–Hall technique. However, it relies on a bulky ultrastable Fabry–Pérot cavity with

Tunable Fano Resonances in Transport through Microwave Billiards

, 2003
We present a tunable microwave scattering device that allows the controlled variation of Fano line shape parameters in transmission through quantum billiards. Transport in this device is nearly fully coherent.

On the Modeling of Irreversibility by Relaxator Liouville Dynamics

Annalen der Physik, Volume 538, Issue 2, February 2026.
A general approach to modeling irreversibility starting from microscopic reversibility is presented. A relaxator that breaks reversibility condenses in the Liouville operator of the relevant degrees of freedom. The irreversible relaxator Liouville equation contains memory effects and initial correlations of all degrees of freedom. Stationary states are

Control of quantum interference in molecular junctions: Understanding the origin of Fano and anti- resonances

, 2013
We investigate within a coarse-grained model the conditions leading to the appearance of Fano resonances or anti-resonances in the conductance spectrum of a generic molecular junction with a side group (T-junction).

Quantum Theory of Surface Lattice Resonances

Nanophotonics, Volume 15, Issue 3, 12 February 2026.
ABSTRACT The collective interactions of nanoparticles arranged in periodic structures give rise to high‐Q $Q$ in‐plane diffractive modes known as surface lattice resonances. Although these resonances and their broader implications have been extensively studied within the framework of classical electrodynamics and linear response theory, a quantum ...

Excitation of high Q-factor Fano resonance in asymmetric THz metamaterial for microplastics sensing applications

Results in Engineering
The increasing demand for terahertz (THz) technology in various applications has resulted in the need for high-quality, highly sensitive THz sensors. This work analyses the refractive index sensing properties of a Fano resonance THz metasurface.
