Nonlinear photoconductivity in pump-probe spectroscopy. I. Optical coefficients

Leya Lopez, Derek G. Sahota, J. Steven Dodge

We analyze the optical pump-probe reflection and transmission coefficients when the photoinduced response depends nonlinearly on the incident pump intensity. Under these conditions…

Status of the Spurious Evidence for Photoinduced Superconductivity

J. Steven Dodge, Leya Lopez, Derek G. Sahota

After more than a decade of research on photoinduced superconductivity, the experimental evidence for its existence remains controversial. Recently, we identified a fundamental fla…

Optical Saturation Produces Spurious Evidence for Photoinduced Superconductivity in KC

J. Steven Dodge, Leya Lopez, Derek G. Sahota

We discuss a systematic uncertainty in time-resolved optical conductivity measurements that becomes important at high pump intensities. We show that common optical nonlinearities c…

Maximum-likelihood parameter estimation in terahertz time-domain spectroscopy

Laleh Mohtashemi, Paul Westlund, Derek G. Sahota +4

We present a maximum-likelihood method for parameter estimation in terahertz time-domain spectroscopy. We derive the likelihood function for a parameterized frequency response func…

Many-body recombination in insulating cuprates

Derek G. Sahota, Ruixing Liang, M. Dion +4

We study the pump-probe response of three insulating cuprates and develop a model for its recombination kinetics. The dependence on time, fluence, and both pump and probe photon en…

Transient terahertz photoconductivity of insulating cuprates

J. C. Petersen, A. Farahani, D. G. Sahota +2

We establish a detailed phenomenology of photocarrier transport in the copper oxide plane by studying the transient terahertz photoconductivity of SrCuOCl and YBaCu…
