Quantum interferometry reveals the chosen pathway of coherent phonon generation
Scientists at Tokyo Institute of Technology and Keio University investigated the excitation and detection of photogenerated coherent phonons in polar semiconductor GaAs through an ultrafast dual pump-probe laser for quantum interferometry. …
Magnetic north is shifting fast. What’ll happen to the northern lights?
As magnetic north shifts increasingly away from the geologic north pole – towards Siberia – studies suggest the northern lights could move with it. Source: https://earthsky.org/earth/magnetic-north-pole-shift-northern-lights…
