Self-Assembled Triply Periodic Minimal Surfaces as moulds for Photonic Band Gap Materials [PDF]
, 1998 We propose systems with structures defined by self-assembled triply periodic minimal surfaces (STPMS) as candidates for photonic bandgap materials. To support our proposal we have calculated the photonic bands for different STPMS and we have found that, at least, the double diamond and gyroid structures present full photonic bandgaps.

A 5D view of the Alpha Per, Pleiades, and Praesepe clusters [PDF]
A&A 628, A66 (2019), 2019 Aims: Our scientific goal is to provide revised membership lists of the Alpha Per, Pleiades, and Praesepe clusters exploiting the second data release of Gaia and produce five-dimensional maps (ra, dec, parallax, pmRA, pmDEC) of these clusters. Methods: We implemented the kinematic method combined with the statistical treatment of parallaxes and ...

Black holes and general Freudenthal transformations
Journal of High Energy Physics, 2019 We study General Freudenthal Transformations (GFT) on black hole solutions in Einstein-Maxwell-Scalar (super)gravity theories with global symmetry of type E 7. GFT can be considered as a 2-parameter, a, b ∈ ℝ, generalisation of Freudenthal duality: x → x

Reaction mechanisms in the 6Li+59Co system [PDF]
Nucl. Phys. A 821, 36-50 (2009)., 2008 The reactions induced by the weakly bound 6Li projectile interacting with the intermediate mass target 59Co were investigated. Light charged particles singles and $\alpha$-$d$ coincidence measurements were performed at the near barrier energies E_lab = 17.4, 21.5, 25.5 and 29.6 MeV.

Asymptotic and Exact Solutions of Perfect-Fluid Scalar-Tensor Cosmologies [PDF]
Phys.Rev. D59 (1999) 124015, 1999 We present a method which enables exact solutions to be found for at homogeneous and isotropic scalar-tensor cosmologies with an arbitrary $\omega(\Phi)$ function and satisfying the general perfect fluid state equation $P=(\gamma-1)\rho c^2$. This method has been used to analyze a wide range of asymptotic analytical solutions at early and late times ...
