Laser Cooling of an Optomechanical Crystal Resonator to Its Quantum Ground State of Motion [PDF]
, 2012 Quantum mechanics continues to intrigue us with bizarre predictions that seemingly run counter to our everyday classical intuition. Superposition, zero-point motion, entanglement, and inescapable bounds on measurement precision are just a few purely ...

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
