Text en actes de congrés
Accés obertWe perform a theoretical study on the group velocity for finite thin artificial opal slabs made of a reduced number of layers in the spectral range where the light wavelength is on the order of the lattice parameter. The ... -
Anomalous scaling in the Zhang model
(Springer, 2000-10-04)
Article
Accés obertWe apply the moment analysis technique to analyze large scale simulations of the Zhang sandpile model. We find that this model shows different scaling behavior depending on the update mechanism used. With the standard ... -
Anomalous structural evolution and glassy lattice in mixed-halide hybrid perovskites
(2022-04-28)
Article
Accés obertHybrid halide perovskites have emerged as highly promising photovoltaic materials because of their exceptional optoelectronic properties, which are often optimized via compositional engineering like mixing halides. It is ... -
Anomalous subduction initiation: young under old oceanic lithosphere
(2021-05-17)
Article
Accés obertWhen subduction initiates along a transform fault, it is often interpreted that the older and therefore denser oceanic lithosphere should evolve into the downgoing plate. However, in the western Pacific, several geological ... -
Anomalous transient blueshift in the internal stretch mode of CO/Pd(111)
(American Physical Society (APS), 2023-03-10)
Article
Accés obertIn time-resolved pump-probe vibrational spectroscopy the internal stretch mode of polar molecules is utilized as a key observable to characterize the ultrafast dynamics of adsorbates on surfaces. The adsorbate nonadiabatic ... -
