Quantum Faraday Effect in the Universe
, 2017 We study the Quantum Faraday rotation starting from the photon self-energy in the presence of a constant magnetic field. The Faraday angle is calculated in the non-degenerate regime and for weak field limit.

Faraday-Talbot Effect from a Circular Array of Pillars
, 2017 When an oil bath is vertically oscillating with an acceleration above some critical value, known as the Faraday threshold, the bath surface becomes unstable and nonlinear standing wave patterns emerge.
