Ultrafast magnetic field induced by anisotropy in carbon nanotubes irradiated by intense laser fields [PDF]
EPJ Web of ConferencesWe report an unexpected result of the anisotropy of the nonlinear optical response of carbon nanotubes, inherent to their chirality. Using a model based on the resolution of the semiconductor Bloch equations, we theoretically demonstrate that, upon ...

Sagnac with Double-Sense Twisted Low-Birefringence Standard Fiber as Vibration Sensor
Sensors, 2022 In this work, we study a double-sense twisted low-birefringence Sagnac loop structure as a sound/vibration sensing device. We study the relation between the adjustments of a wave retarder inside the loop (which allows controlling the transmission ...
