What are we all up to?

2022

AMC Group's Fall celebration!

After Nanako beat everyone at pool and Srijan beat Tom at ping-pong, we all enjoyed some good food, music, and even better company! Not to mention the baked brie, which disappeared in no time.

And, of course, here is Mateo celebrating Halloween a little late in his lobster costume!

October 24: Can you extract hot excitons from 2D materials in a photoelectrochemical cell? And unambiguously demonstrate it? Read about it here. We combine calculations of electron and exciton distributions in MoS2 with innovative contact design, time-resolved spectra, and electrochemical measurements to suggest a simple mechanistic picture of hot carrier extraction in these materials. This opens up exciting prospects for energy conversion and photoelectrocatalysis! Congratulations, Tom! Dream team with the Krummel and Sambur groups!

October 20: Want to do protein folding in an easy, reliable, and noise-resilient way? Read about it here. We introduce and show how we can use our noise-averaged discrete-time GME to capture the long-timescale dynamics of the FiP35 WW domain and the human argonaute complex -- and get cost savings of up to 1000 in comparison with state-of-the-art Markov State Models. And did you see those folding times? Accurate to within 8% even when you use only 10% of the total data! Now, on to more complex protein systems! Congratulations, Anthony & Tom! Great collaboration with the Huang group and Tom Markland!

October 1: Second paper from the group to appear on arXiv! Controlling decoherence in quantum technology is hard. Really hard. To develop and apply decoherence mitigation schemes, you need to learn details about a qubit's environment. Here, we show how to do it much more easily and cheaply than previously thought possible (i.e., without a long string of technologically challenging and often imperfect laser pulses) -- and with greater accuracy! Read about it here. Awesome collaboration with Shuo Sun! Congratulations, Arian and Nanako!

September 28: First paper from the group to appear on arXiv! Ever wondered about how to obtain a highly compact and complete description of non-Markovian dynamics? Read about it here. We show how to combine our framework with any dynamical method, explain how and when this framework works, suggest what to do when it doesn't, and even introduce a discrete-time version that is compatible with low-resolution data. This work has wide-ranging applications from quantum information, to charge and energy transfer in the condensed phase, glassy dynamics, protein folding, and even cosmic expansions! Congratulations, Tom!

August 5: Jack, our high school intern in the AMC group, completes research on quantum master equations & his work with Anthony as his graduate mentor. Jack is headed off to great things as an undergraduate at Cornell University. Good luck, Jack!

August 23: Srijan receives the Graduate Assistance in Areas of National Need (GAANN) fellowship award for his work in the group developing quantum dynamics methods to predict and tune the optoelectronic properties of sustainable polymers. Congratulations, Srijan!

August 17: The Chemistry department recognizes Zach (left) & Anthony (right) with the Graduate Teaching Excellence Award for their great work as Teaching Assistants in Physical and General Chemistry. Congratulations, Anthony & Zach!

August 9: Srijan's Master's degree work on a periodically driven quantum thermal transistor gets highlighted in the APS Physics Magazine. Congratulations, Srijan!
