Experimental quantification of decoherence via the Loschmidt echo in a many spin system with scaled dipolar Hamiltonians
(2015)
We performed Loschmidt echo nuclear magnetic resonance experiments to study decoherence under a scaled dipolar Hamiltonian by means of a symmetrical time-reversal pulse sequence denominated Proportionally Refocused Loschmidt ...
Search for gravitational wave ringdowns from perturbed intermediate mass black holes in LIGO-Virgo data from 2005-2010
(2014)
We report results from a search for gravitational waves produced by perturbed intermediate mass black holes (IMBH) in data collected by LIGO and Virgo between 2005 and 2010. The search was sensitive to astrophysical sources ...
Asymptotic structure of the null surface formulation and the classical graviton
(2016)
The dynamical equations for the null surface formulation of general relativity for purely radiative spacetimes are derived. Those asymptotically flat spacetimes describe the nonlinear evolution of gravitational radiation ...
High resolution, week-long, locomotion time series from Japanese quail in a home-box environment
(2016-06-07)
Temporal and spatial patterns of locomotion reflect both resting periods and the movement from one place to another to satisfy physiological and behavioural needs. Locomotion is studied in diverse areas of biology such as ...
The index of symmetry of compact naturally reductive spaces
(2014)
We introduce a geometric invariant that we call the index of symmetry, which measures how far is a Riemannian manifold from being a symmetric space. We compute, in a geometric way, the index of symmetry of compact naturally ...
Layered double hydroxides-indomethacin nanohybrids : intercalation, pH influence, stability and release properties
(2016)
In this work, three pH values (8, 9 and 10) were studied for the insertion of Indomethacin (Indo) molecules into Layered Double Hydroxides (LDHs). The obtained results showed that the LDH materials have been a good storage ...
Irradiated graphene as a tunable Floquet topological insulator
(2014)
In the presence of a circularly polarized mid-infrared radiation graphene develops dynamical band gaps in its quasienergy band structure and becomes a Floquet insulator. Here, we analyze how topologically protected edge ...
Virtual laboratory for a first experience in dynamics
(2014)
New technologies contribute to the learning process of scientific disciplines. In particular Physics learning may take advantage of these techniques by implementing experimental practices in simulation environments. Our ...
Analysis of X-ray absorption spectra of the K and L 2,3 edges of GaN within the FP-LAPW method
(2016)
Gallium nitride, GaN, is a semiconductor material with several technological applications and therapeutic potential to inhibits the proliferation of tumor cells. In this work we performed all electron self consistent ...
Generalization of entropy based divergence measures for symbolic sequence analysis
(2014)
Entropy based measures have been frequently used in symbolic sequence analysis. A symmetrized and smoothed form of Kullback-Leibler divergence or relative entropy, the Jensen-Shannon divergence (JSD), is of particular ...
