The effect of magnetic field on electron-boson spectral function in the cuprates

We will report results of our infrared spectroscopy studies of high T$_c$ cuprates in high magnetic field. Several families of cuprates, such as YBCO, Bi2212, LBCO and NCCO have been studied using magneto-optical measurements, with magnetic field as high as 18 Tesla. From these measurements we extract the electron-boson spectral function $\alpha^2F(\omega)$ and estimate the effect magnetic field has on it. The results will be critically compared with the existing theoretical models.
