To date, epsilon near zero (ENZ) responses, characterized by an infinite phase velocity, are primarily achieved by applying a monochromatic light source to a tailored metamaterial. Here, we derive the equations for inducing a dynamically generated broadband ENZ response in a large class of many-body systems via tracking and feedback control. We further find that this response leads to a current-energy relationship identical to that of an ideal inductor. Using a Fermi-Hubbard model, we numerically confirm these results which have the potential to advance optical computation on the nanoscale.

    By solving the tracking equation E + α|E|^{1/ν} sgn(E) = ⟨F_z⟩ at every time step, the authors make hydrogen's dipole acceleration follow sublinear power laws for several exponents.

    physics.chem-ph 2025-05 conditional novelty 5.0 of 10

    Solvated electrons in polar liquids act as epsilon-near-zero materials in the terahertz range, with a concentration-tunable zero-crossing frequency producing characteristic pulse reshaping.
