## Description

- description: "The elastic interaction causes a two-step conversion from the low-spin
    (LS) to the high-spin state (HS) following a femtosecond laser pulse excitation.
    These steps occur on different\r\ntimescales: a spin conversion (elastic step)
    in a short time due to pressure propagation and a late spin conversion (thermal
    step) resulting from heat diffusion. In this paper, we provide a\r\nbrief review
    of models for spin crossover phenomena, emphasizing the role of the difference
    of degeneracy of the HS state and LS state and elastic interaction due to changes
    in local\r\nstructures. We also review theoretical approaches to these effects.
    Additionally, to analyze the dynamical process of spin conversion after photo-irradiation,
    it is necessary to consider\r\nmechanisms of heat transfer among spins. Recently,
    we proposed a two-temperature model that incorporates both lattice and spin temperatures,
    which enables us to reproduce\r\nthe two steps under an early uniformization of
    the lattice temperature, highlighting the importance of the timescales of these
    processes. Furthermore, we explore possible mechanisms to separate the two steps
    by examining the different timescales of processes of spin conversions by mechanical
    and entropic forces, and also by considering changes of local temperature due
    to spin conversion. \r\n\r\n"
