PQI Distinguished Lecture: Dr. Hideo Mabuchi

Dr. Hideo Mabuchi from Stanford University gave a talk titled "Coherent nonlinear dynamics and the physics of computation".

His early scientific research was focused on understanding open quantum systems, quantum measurement, and the quantum-to-classical transition. In recent years his research group has turned towards fundamental issues of quantum engineering, such as quantum nonlinear dynamics, quantum feedback control and quantum model reduction. Along the way his group has also worked substantially on single-molecule biophysics, quantum information science, and quantum materials. In parallel with directing his group's sponsored research, Hideo has developed a deep personal interest in exploring the interfaces of modern science with traditional craft, aesthetic philosophy and new materialism.

How Do You Take a Picture of Light?

  • By Jenny Stein
  • 19 June 2020

Light travels at a velocity of 300 nm/fs, and nothing travels faster than that, so you will never be able to take a snapshot, as you might like, of it interacting with matter. But if you overlap two light identical pulses, their in-phase fields will add, and out-of-phase fields will subtract, causing the light intensity to be modulated on the wavelength scale and thereby allowing light fields to be imaged by a nonlinear process.

Hrvoje Petek and his group have developed a method to image light on the nanofemto scale by interferometric time-resolved photoemission electron microscopy and recently published a review article on this work in Chemical Reviews.

James McKone Selected as a 2020 Beckman Young Investigator

  • By Jenny Stein
  • 19 June 2020

James McKone, Assistant Professor in the Department of Chemical and Petroleum Engineering at the University of Pittsburgh, was selected as one of the ten 2020 Beckman Young Investigator awardees. The awardees exemplify the Foundation’s mission of supporting the most promising young faculty members in the early stages of their academic careers in the chemical and life sciences, particularly to foster the invention of methods, instruments, and materials that will open new avenues of research in science. 

His research focuses on designing a new generation of enzyme-like catalysts that use renewable electricity to recycle carbon dioxide emissions back into useful fuels and chemicals.

“Over the last several decades, the cost of renewable electricity has dramatically decreased to the point where building a new solar or wind farm is, in many cases, more economical than continuing to run a coal-fired power plant,” said McKone.

PQI June Social Hour

Speaker(s): 
Multiple Speakers
Dates: 
Friday, June 26, 2020 - 2:00pm

Join the PQI Director and Staff for a social hour on Friday, June 26 from 2-3pm (click here to join)!
 

We'll be using the platform Online Town to host a meet-up in a virtual PQI office. We won't have any food, but come chat and tell us about the trials of the spring semester, your plans for getting back into lab, how PQI could help with anything, the latest video game, or just pop in to casually see who's around. We'll be there.
