Special Seminar: "Exploiting the roles of photon spin and electron spin in light-matter interaction"

Li He (University of Minnesota)
- David Rittenhouse Laboratory, A6

In light-matter interaction, the conservation of angular momentum requires the angular momentum transfer between light and matter, which consequently couples light polarization to various state variables of materials…



Condensed Matter Seminar: "The physical chemistry of natural selection: How can we explain the high yields and high rates of biochemical reactions?"

Jean-Louis Sikorav (Ministère de l'Economie et des Finances)
- David Rittenhouse Laboratory, A4

The goal of this seminar is to present the main findings of an ongoing inquiry of the foundations of biology (1). The purpose of this investigation is to describe the elements, the logic and the principles of biology…

High Energy Theory Seminar: (Stochastic Particle Production in the Early Universe)

Mustafa Amin (Rice University)
David Rittenhouse Laboratory, 2N36

I will show some intriguing hints of universality in the occupation number of spectator/daughter fields that experience repeated stochastic particle production during inflation and reheating. The calculations are…

Condensed Matter Seminar: "Long Term 3D Imaging by FIBSEM for Neurons and Cell Biology and Correlation to Cryo Fluorescence Microscopy"

Harald Hess (Howard Hughes Medical Institute, Janelia Research Campus)
- David Rittenhouse Laboratory, A4

3D Electron microscopy volume data can be acquired by a variety of approaches.  Focused Ion beam – scanning electron microscopy, FIBSEM, offers no limitation on section thickness, so that isotropic voxels with 8 nm…
