Absence of two-phonon quasi-elastic scattering in the normal state of doped--SrTiO by THz pump-probe spectroscopy
K. Santhosh Kumar, David Barbalas, Rishi Bhandia +4
Multi-pulse nonlinear THz spectroscopies enable a new understanding of interacting metallic systems via their sensitivity to novel correlation functions. Here, we investigated the…

Anomalous frequency and temperature dependent scattering in the dilute metallic phase in lightly doped-SrTiO
K. Santhosh Kumar, Dooyong Lee, Shivasheesh Varshney +2
The mechanism of superconductivity in materials with aborted ferroelectricity and the emergence of a dilute metallic phase in systems like doped-SrTiO are outstanding issues in…
