Many-body quasiparticle spectrum of Co-doped ZnO: A GW perspective
(2013)
In transition-metal-doped ZnO the energy position of the dopant 3
d
states relative to the host conduction
and valence bands determines the possibility of long-range ferromagnetism. Density functional theory (DFT)
can ...
Star-planet interactions: I. Stellar rotation and planetary orbits
(2016)
Context. As a star evolves, planet orbits change over time owing to tidal interactions, stellar mass losses, friction and gravitational drag forces, mass accretion, and evaporation on/by the planet. Stellar rotation modifies ...

Spontaneous emission from semiconductor nanocrystals in coupled spherical microcavities
(2005)
We report on the coherent coupling of whispering gallery modes (WGM) in a photonic molecule formed from two melamine-formaldehyde spherical microcavities coated with a thin shell of light-emitting CdTe nanocrystals (NCs). ...
Novel polarization beam splitter with high fabrication tolerance
(2018)
A highly fabrication tolerant polarization beam splitter is presented. The fabrication tolerances are relaxed by adjusting two voltages. Experiments show on-chip losses of 3.5 dB and extinction ratio of 15 dB at C-band
Large infrared nonlinear optical response of C60.
(1991)
C60 buckminsterfullerene exhibits a large ultrafast third-order nonlinear optical response. Degenerate four-wave-mixing
measurements in C60-benzene solutions were
performed using
50-psec pulses at
l.064Itm.The magnitude ...
Machine-learning approaches for the enhancement of 2D and 3D electron microscopy data
(Trinity College Dublin. School of Physics. Discipline of Physics, 2023)
Electron microscopy allows academic and industrial users to investigate the structure and properties of a variety of materials. However, some limitations are imposed by the instrumentation and the nature of the analyzed ...
The hot Jupiter and magnetic activity of V830 Tau
(2017)
We report results of an extended spectropolarimetric and ph
otometric monitoring of the weak-
line T Tauri star V830 Tau and its recently-detected newborn
close-in giant planet. Our obser-
vations, carried out within ...
Dynamics of the plume produced by nanosecond ultraviolet laser ablation of metals
(American Physical Society, 2003)
The dynamics of the ablation plume of a partially ionized plasma produced by a nanosecond UV laser with
different irradiation spot geometries has been explored. We have used an ensemble of quartz crystal microbalances
to ...
