I recorded the presentation and made it available on YouTube. You can watch it here! http://www.ericdavidsson.com/blog/introduction-to-mctdh http://www.ericdavidsson.com/blog/photochemistry-in-the-strong-coupling-regime-a-non-adiabatic-perspective My supervisor recently presented a webinar discussing our research into Polaritonic Chemistry—you can now watch it here! http://www.ericdavidsson.com/blog/photochemistry-in-the-strong-coupling-regime-a-non-adiabatic-perspective http://www.ericdavidsson.com/blog/bad-cavities When Covid made it impossible to meet with the research community and discuss our research, we put a 10 minute introduction to our new paper on YouTube.

Well, back to frantic typing. I probably have another month worth of LaTeX compulsion. http://www.ericdavidsson.com/blog/drafting-the-abstract-for-my-master-thesis-draft http://www.ericdavidsson.com/blog/deriving-the-thermal-state-in-quantum-mechanics Finding a detailed, yet easy to follow, derivation of the thermal state for a quantum system wasn't that easy. So I wrote up my own derivation. You can read it here. http://www.ericdavidsson.com/blog/deriving-the-thermal-state-in-quantum-mechanics http://www.ericdavidsson.com/blog/elastic-neutrino-scattering Writing some new science history, Juan Collar and his colleagues have detected the signature of elastic scattering events between neutrinos, and nuclei of atoms, for the first time. And they used a detector that would fit on your desk! http://www.ericdavidsson.com/blog/elastic-neutrino-scattering http://www.ericdavidsson.com/blog/3blue1brown-the-essence-of-calculus Today, 3Blue1Brown released the first video in a new series about the essence of calculus. You should watch it. http://www.ericdavidsson.com/blog/3blue1brown-the-essence-of-calculus http://www.ericdavidsson.com/blog/wired-has-an-article-about-sexual-harassment-in-science "I look around and see my female colleagues exchanging glances and saying this has been going on for a long time, and it’s about time we start talking about it." –Eric Davidson(That is not me, I spell my name with a Swedish double s.) http://www.ericdavidsson.com/blog/wired-has-an-article-about-sexual-harassment-in-science http://www.ericdavidsson.com/blog/first In space, no one can hear you scream.
