Electric Field Resolved Image Formation in a Widefield Optical Microscope

Arjun Ashoka, Juhwan Lim, Akshay Rao +1

Visualizing the spatiotemporal evolution of the electric field of light is fundamental to optics, from designing photonic devices to developing next-generation microscopes. However…

Fieldoscopy at the Quantum Limit

Dmitry A. Zimin, Arjun Ashoka, Florentin Reiter +1

We demonstrate a novel concept for measuring time-varying electric field transients of petahertz-scale photons down to a single-photon regime. We observe a clear transition from cl…

Unexpected Effectiveness of Berezinskii-Kosterlitz-Thouless Description of Electron Paramagnetic Resonance Linewidth Behaviour in the 3-Dimensional Manganite Bi $_{0.5}$ Sr $_{0.5}$ Mn $_{0.9}$ Cr $_{0.1}$ O $_{3}$

A. Ashoka, K. S. Bhagyashree, S. V. Bhat

We find that the temperature dependence of the Electron Paramagnetic Resonance (EPR) linewidth observed in Bi $_{0.5}$ Sr $_{0.5}$ Mn $_{0.9}$ Cr $_{0.1}$ O $_{3}$ (BSMCO), as well as in cert…
