Time-domain vector ptychography

Optics Express
We demonstrate the reconstruction of the instantaneous polarization state of ultrafast laser pulses through vectorial time-domain ptychography. We introduce the formalism, investigate the algorithm’s capacities through simulations, and finally validate it by reconstructing several polarization states from experiments.

Time-domain braiding of anyons

Science
Anyons are quasiparticles that keep a robust memory of particle exchanges via a braiding phase factor. When an anyon excitation is emitted toward a quantum point contact (QPC) in a fractional quantum Hall (FQH) fluid, this memory translates into tunneling events that may occur long after the anyon excitation has exited the QPC.

Thermoacoustic instability - a dynamical system and time domain analysis

, 2014
This study focuses on the Rijke tube problem, which includes features relevant to the modeling of thermoacoustic coupling in reactive flows: a compact acoustic source, an empirical model for the heat source, and nonlinearities.

Feedback Beamforming in the Time Domain

Sensors
Real-time source localization is crucial for high-end automation and artificial intelligence (AI) products. However, a low signal-to-noise ratio (SNR) and limited processing time can reduce localization accuracy. This work proposes a new architecture for a time-domain feedback-based beamformer that meets real-time processing demands. The main objective
