Origin, strength, and speed of the nonlinear optical response of transparent conducting oxides to single-cycle optical pulses
Ieng-Wai Un, Subhajit Sarkar, Yonatan Sivan
We present a first-principles study of the nonlinear optical response of transparent conducting oxides at the nanoscale due to excitation by intense, extremely short pulses based o…
Quantum-optical theory of the few femtosecond nonlinear optical response of Drude metals with a non-parabolic conduction band
Ieng-Wai Un, Subhajit Sarkar, Yonatan Sivan
We develop an energy-space density matrix framework to investigate the interaction of extremely short optical pulses (ESPs) with transparent conducting oxides (TCOs). This approach…
Time Crystals from single-molecule magnet arrays
Subhajit Sarkar, Yonatan Dubi
Time crystals, a unique non-equilibrium quantum phenomenon with promising applications in current quantum technologies, mark a significant advance in quantum mechanics. Although tr…
Ballistic vs. diffusive transport in metals
Yonatan Sivan, Ieng-Wai Un, Subhajit Sarkar
Using the Boltzmann transport model, we show that, somewhat unintuitively, ballistic transport of electrons in metals is weaker than diffusive transport. This happens because the f…
Temperature-dependence of the chirality-induced spin selectivity effect -- experiments and theory
Seif Alwan, Subhajit Sarkar, Amos Sharoni +1
The temperature dependence of the chirality-induced spin selectivity (CISS) effect can be used to discriminate between different theoretical proposals for the mechanism of the CISS…
An electronic-based model of the optical nonlinearity of low-electron-density-Drude materials
Ieng Wai Un, Subhajit Sarkar, Yonatan Sivan
Low electron density Drude (LEDD) materials such as indium tin oxide (ITO) are receiving considerable attention because of their combination of CMOS compatibility, unique epsilon-n…
