Looks ugly and, ah, preliminary to say the least, I know, but to me it’s beautiful. After trying some time, we are finally capable of taking proper polarization resolved plots of nonlinear response of our epitaxial BN films 8-)

Excited to share a new colloquium by Prof. Andrea Cavalleri, a founding director of the MPI for the Structure and Dynamics of Matter 🎓✨ In his Nordita talk, he explores how coherent electromagnetic radiation can induce unexpected phases like magnetic order, ferroelectricity, and high-temperature superconductivity.

Full abstract: In this colloquium, I will discuss how coherent electromagnetic radiation, when tuned to drive collective modes in quantum materials, can be used to induce unexpected dynamical phases. An illustrative set of examples will be discussed for the nonlinear control of the crystal lattice, which is used to induce magnetic order in paramagnetic materials, ferroelectricity in paraelectrics, non-equilibrium superconductivity at high temperatures, and other dynamical phases. These studies open up new directions in fundamental research but also expose a set of phenomena that will inevitably be encountered if one wishes to use quantum materials in ultra-high bit-rate applications.

Homemade Raman Laser Is Shaken, Not Stirred

You wouldn’t think that shaking something in just the right way would be the recipe for creating laser light, but as [Les Wright] explains in his new video, that’s pretty much how his D…

New Lightwave Explorer release for September! This is my open source nonlinear optics simulator. Windows/Mac downloads here: https://github.com/NickKarpowicz/LightwaveExplorer/releases/tag/2023.09.01
And Linux available on Flathub.
Changes:
- New multithreading modes for CPU-based propagation, and optimizations
- better handling of math in user scripts

More details on the website :)

Also, I'm new to Mastodon (and never used the thing that was once Twitter) but apparently I should add tags? #NonlinearOptics #OpenSource #Ultrafast

Release 2023.09.01 · NickKarpowicz/LightwaveExplorer

This release adds the following fixes and improvements: Adds a new CPU-based propagation mode on Linux/Windows using C++ std::execution::par instead of OpenMP, which on some computers is nearly tw...

La refracción de un solitón óptico en un gas de solitones - La Ciencia de la Mula Francis

Se llama gas de solitones a un sistema con gran número de solitones en interacción mutua (en la práctica bastan decenas de solitones). Cuando un solitón de gran amplitud atraviesa […]

I am a #PhDStudent in #ultrafast #nonlinearoptics #materialscience area at #Imperialcollege in #London. Hopefully, I used enough tags to find my people on #academicmastodon - great to meet you all!
#Introduction

By combining the advantages of both electrical and optical #modulation, physicists and chemists @[email protected], led by Prof. Giancarlo Soavi, have developed a particularly effective method for nonlinear signal modulation in 2D materials. #NonlinearOptics
