Congratulations to Eric R. Bittner, Carlos Silva-Acuña, and Hao Li, members of the Canada Excellence Research Chair in Light-Matter Interactions (CERC-LM), on their new publication:“Liouvillian Geometry of Multidimensional Spectra: Pathway Transport and Observational Holonomy in Open Quantum Systems.” The work introduces a novel geometric framework for understanding pathway transport and spectral signatures in open quantum systems, offering new insights into nonlinear spectroscopy.
