To anyone begging for a QC Lab installation tutorial video...

Your wish is granted!

A belated congrats to Alex Krotz for successfully defending his thesis last fall! Best of luck with continuing your academic journey at UC Berkeley!

The latest by Team member @mhhsieh.bsky.social. Combining the decoupled mean-field approach with a focusing of initial classical coordinates yields a quantum electrodynamical method with high accuracy across cavity lengths.

Today we are releasing QC Lab – a Python package for quantum–classical dynamics simulations. And what would a software release be without a hype video??

Optically Addressing Circularly Polarized Vibrations in Molecules Circularly polarized (CP) vibrations are the nuclear-motion analog of CP light, emerging in molecules with non-Abelian point-group symmetry that support orthogonal and degenerate vibrational normal mo...

Team member Chientzu Lin shows how circularly-polarized nuclear vibrations in molecules can absorb and sustain angular-momentum-like states from optical fields. Just out in the Journal of Physical Chemistry Letters @pubs.acs.org.

Thanks @isabelle-dume.bsky.social for this insightful account of our recent study on the chiroptical response of a chiral crystal!

Our paper has been selected as the cover of Journal of Chemical Physics!🎉

We showed that self-consistent mixed quantum-classical (MQC) dynamics can reproduce persistent yet anharmonic Rabi oscillations, providing a new perspective for MQC approach for quantum systems.

Differential absorption of circularly polarized light by a centrosymmetric crystal Crystalline solids are governed by universal structure-property relationships derived from their crystal symmetry, leading to paradigmatic rules on what properties they can and cannot exhibit. A long-...

Our collaboration with the Poeppelmeier, Goldsmith, & Hersam groups shows the material LCSO to exhibit chiroptics, in spite of its centrosymmetry. Out today in @science.org. Featuring former Team member Andrew!

Mixed quantum–classical dynamics yields anharmonic Rabi oscillations We apply a mixed quantum–classical (MQC) approach to the quantum Rabi model, involving a classical optical field coupled self-consistently to a quantum two-leve

Team member Ming-Hsiu Hsieh shows anharmonicities arising when coupling harmonic classical and quantum systems.

This work just appeared in the Journal of Chemical Physics @aip.bsky.social, as part of the Emerging Investigators Special Collection.

Molecular engineering charge transfer and triplet exciton formation in donor–acceptor cocrystals Organic donor–acceptor (D–A) cocrystals are gaining attention for their potential applications in optoelectronic devices. This study explores the dynamics of ch

Just out! A joint effort with the Wasielewski group, showing how a change in exciton delocalization promotes intersystem crossing in donor–acceptor cocrystals. Featuring Team member extraordinaire Antonio!
