Photonic negative differential transistor based on cavity polaritons
New Journal of Physics, 2023 We theoretically provide a scheme for realizing a photonic negative differential transistor (NDT) by using a two-port asymmetric system with cavity exciton polaritons.

Dynamics of laser-induced tunable focusing in silicon
Scientific Reports, 2022 We report here on focusing of a probe IR (λ = 1.55 μm) laser beam in silicon. The focusing is done by a second pump laser beam, at λ = 0.775 μm and 30 ps pulse width, with a donut shape that is launched collinearly and simultaneously (with some delay ...

Waveform-sequencing for scanning tunneling microscopy based pump-probe spectroscopy and pulsed-ESR
MethodsX, 2019 We present here the straightforward implementation of pump-probe methods into existing scanning tunneling microscopy (STM) systems. Our method uses the waveform-sequencing abilities of a standard arbitrary waveform generator (AWG) and a simple mechanical

Nonlinear generation of hollow beams in tunable plasmonic nanosuspensions
APL Photonics, 2023 We experimentally demonstrate that a probe beam at one wavelength, although exhibiting a weak nonlinear response on its own, can be modulated and controlled by a pump beam at another wavelength in plasmonic nanosuspensions, leading to ring-shaped pattern

Time-Resolved Measurement of Interatomic Coulombic Decay in Ne_2 [PDF]
, 2013 The lifetime of interatomic Coulombic decay (ICD) [L. S. Cederbaum et al., Phys. Rev. Lett. 79, 4778 (1997)] in Ne_2 is determined via an extreme ultraviolet pump-probe experiment at the Free-Electron Laser in Hamburg.

Generation and coherent control of terahertz acoustic phonons in superlattices of perovskite oxides
New Journal of Physics, 2021 We utilized transmission-type pump–probe technique to investigate coherent acoustic phonons in the superlattices of perovskite oxides such as SrIrO _3 /SrTiO _3 and SrRuO _3 /SrTiO _3 . Because the films in the superlattices are of high-quality and their
