Many-body quantum geometric effects and entanglement at the 3D metal-insulator quantum phase transition
Jason Y. Yan, Xiaoyu Guo, R. Bhandia +3
Quantum geometry has emerged as a unifying concept across condensed matter physics, underlying phenomena from nonlinear topological response to flat-band superconductivity. While u…

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…

Energy and momentum relaxation through the Curie temperature in an itinerant ferromagnet
Rishi Bhandia, Tim Priessnitz, Jiahao Liang +8
In this work, we combine conventional linear response time-domain THz spectroscopy with non-linear THz-pump THz-probe techniques to study metallic strained thin films of $\mathrm{C…
