    Correlation of optical anisotropy with structural changes in Ge2Sb2Te5 by Shanmugam, J

    Published 2018
    “…While the amorphous-to-crystalline phase transition in GST has generally been understood to proceed via a thermal mechanism, significant optical anisotropy (measured by circular dichroism (CD) spectroscopy in this work) strongly suggests that there is an electronic athermal component of the phase change induced by the handedness of circularly polarised nanosecond laser pulses and implies the existence of chiral structures or motifs. …”

    Singlet-triplet dephasing in radical pairs in avian cryptochromes leads to time-dependent magnetic field effects by Golesworthy, M, Zollitsch, T, Luo, J, Selby, D, Jarocha, L, Henbest, K, Pare-Labrosse, O, Bartoelke, R, Schmidt, J, Xu, J, Mouritsen, H, Hore, P, Timmel, C, Mackenzie, S

    Published 2023
    “…B1/2, a parameter that characterizes the magnetic field-dependence of the reactions, was found to be larger than expected on the basis of hyperfine interactions and to increase with the delay between pump and probe laser pulses. Semiclassical spin dynamics simulations show that this behavior is consistent with a singlet–triplet dephasing (STD) relaxation mechanism. …”
