We demonstrate how electric fields with arbitrary time profile can be used to control the time-dependent parameters of spin and orbital exchange Hamiltonians. Analytic expressions for the exchange constants are derived from a time-dependent Schrieffer-Wolff transformation, and the validity of the resulting effective Hamiltonian is verified for the case of a quarter-filled two-orbital Hubbard model, by comparing to the results of a full nonequilibrium dynamical mean-field theory simulation. The ability to manipulate Hamiltonians with arbitrary time-dependent fields, beyond the paradigm of Floquet engineering, opens the possibility to control intertwined spin and orbital order using laser or THz pulses which are tailored to minimize electronic excitations.

  1. $\eta$--paired superconducting hidden phase in photodoped Mott insulators

    cond-mat.str-el 2019-08 conditional novelty 7.0 of 10

    Photodoping a repulsive Hubbard Mott insulator can stabilize a metastable eta-pairing superconducting phase, detectable through a zero-frequency conductivity peak and negative high-frequency conductivity.

  2. Nonthermal order by disorder

    cond-mat.str-el 2024-12 conditional novelty 6.0 of 10

    Anisotropic, nonthermal fluctuations can transiently stabilize order parameter configurations that are not minima of the equilibrium free energy, through mutual feedback between order and fluctuations.
