In the course of my group’s efforts to discover new asymmetric catalytic reactions, we have had occasion to perform deep mechanistic analyses of the catalysts we have discovered. In this lecture, I will relate different stories where seemingly minor “misbehaviors” in our experimental data were examined closely and found to ...
With ~30 high-silica rhyolite domes and flows and a total eruptive volume of ~5-8.5 km3(DRE), the Mono Craters volcanic chain is one of the youngest and most active silicic systems in North America. Effusive products range in age from ~42 ka to 0.7 ka and exhibit changes in mineralogy (biotite-, orthopyroxene-, or fayalite-bearing) and crystallinity through time. Ion microprobe 238U-230Th dating of allanite and zircon surfaces ...
Strongly interacting electrons exhibit a rich variety of striking phenomena in quantum materials, from the fractional quantum Hall effect to chiral superconductivity. Yet our understanding remains limited by the difficulty of solving the many-electron Schrödinger equation in a vast Hilbert space. In this talk, a “first-principles AI” framework is introduced ...

There’s Plenty of Diffusion at the Bottom The formulation of quantum mechanics in the late 1920s forever changed physics. More recently, quantum materials have emerged, offering fascinating opportunities in physical chemistry. Elementary interactions mediated by the diffusion of electrons, protons, atoms, molecules, and other quasiparticles in quantum materials give rise to intriguing phases and enable advanced technologies. ...

Stanford physicist Maya Beleznay on Weighing Black Widow Pulsars - What would Robert Oppenheimer and a modern physicist have in common? Neither could tell you how many particles can fit in a city-size ball before collapsing into a black hole! Some neutron stars in our galaxy teeter on the edge of this maximum ...

Astronomy on Tap East Bay - Two TalksThis month, we have two excellent talks lined up: First, Natasha Abrams (UC Berkeley) will discuss the variety of techniques astronomers use to observe and study black holes. Then we’ll hear from Mahlet Shiferaw (Stanford) about the “cosmic web” of dark matter that shapes the Universe!
?Join John as he shares photos and videos from an expedition cruise to the subantarctic islands of New Zealand and Australia as a True Young Explorer with Heritage Expeditions. These regions are designated as UNESCO World Heritage Sites and are home to the highest diversity of breeding penguin and albatross ...
