Linear and non-linear THz spectroscopy of CoNb<sub>2</sub>O<sub>6</sub>

ORAL

Abstract

Understanding both the linear and non-linear spectral responses of magnetic insulators to pulses of THz light is a powerful window into the nature of their low-energy excitations. Here we theoretically study the response in the context of the domain wall bound states of the one-dimensional Ising quantum magnet CoNb2O6, using density matrix renormalization group calculations.
