Analytical theory for three wave-mixing processes in a slightly deformed cylinder
Raksha Singla, W. Luis Mochán
The second order optical response of centrosymmetric materials manifests itself mostly at their surface, being strongly suppressed in their bulk. However, the overall surface respo…
Magnetic Order Driven Ultrafast Phase Transition in NdNiO
V. Stoica, D. Puggioni, J. Zhang +12
Ultrashort x-ray pulses can be used to disentangle magnetic and structural dynamics and are accordingly utilized here to study the photoexcitation of NdNiO (NNO), a model nicke…
Recursive Calculation of the Optical Response of Multicomponent Metamaterials
W. Luis Mochán, Raksha Singla, Lucila Juárez +1
We develop a recursive computational procedure to efficiently calculate the macroscopic dielectric function of multi-component metamaterials of arbitrary geometry and composition w…
Analytical Theory of Second Harmonic Generation from a Nanoparticle with a Non-Centrosymmetric Geometry
Raksha Singla, W. Luis Mochán
We analytically investigate the effect of a non-centrosymmetric geometry in the optical second harmonic (SH) generation from a particle made of a centrosymmetric material, in the i…
Extreme timescale core-level spectroscopy with tailored XUV pulses
R. Singla, D. C. Haynes, K. Hanff +8
A new approach for few-femtosecond time-resolved photoelectron spectroscopy in condensed matter that balances the combined needs for both temporal and energy resolution is demonstr…
Large excitonic binding energy in GaN based superluminescent light emitting diode on naturally survived sub-10 nm lateral nanowires
Debashree Banerjee, Maharaja B. Nadar, Pankaj Upadhyay +7
We demonstrate a novel method for nanowire formation by natural selection during wet chemical etching in boiling Phosphoric acid. It is observed that wire lateral dimensions of sub…
Pressure dependent relaxation in the photo-excited Mott insulator ETF2TCNQ: Influence of hopping and correlations on quasiparticle recombination rates
M. Mitrano, G. Cotugno, S. R. Clark +12
Femtosecond relaxation of photo-excited quasiparticles in the one dimensional Mott insulator ET-F2TCNQ are measured as a function of external pressure, which is used to tune the el…
