Classical free-fall gravimeters based on optical interferometry have been a cornerstone of geophysical research and exploration for decades. However, they suffer from long-term instability, mechanical drift, and they cannot be operated on moving vehicles. The first commercial quantum gravimeters are now available on the market, largely due to advances in lasers and ultra-high vacuum...
Two-dimensional electronic spectroscopy (2DES) has emerged as a powerful tool for studying electronic structure and dynamics in systems ranging from photosynthetic complexes to liquids and solid-state materials. In recent years, motivated by the desire to make spatially resolved measurements and to correlate optical excitation with a wide range of observables, action-detected variants of 2DES...
