Universal self-gravitating skyrmions

Journal of High Energy Physics
The self-gravitating skyrmion is an exact solution of the Einstein SU(2)-Skyrme model describing a topological soliton with baryon number B = 1, living in a 4-dimensional space-time in the presence of a cosmological constant. Here we show that, using the

Speakable and unspeakable in physics of time

EPJ Web of Conferences, 2013
In order to discriminate speakable and unspeakable in physics of time, the single ion optical atomic clock and the double time-slit experiments are considered.

Microscopic parametrizations for gate set tomography under coloured noise

npj Quantum Information
Gate set tomography (GST) allows for a self-consistent characterization of noisy quantum information processors (QIPs). The standard approach treats QIPs as black boxes only constrained by the laws of physics, attaining full generality at a considerable ...

The first applications of the relativistic Second Tamm-Damncoff approximation in doubly-magic nuclei [PDF]

EPJ Web of Conferences
Understanding nuclear collective excitations and processes relevant for astrophysics requires theoretical frameworks that extend beyond the lim­itations of the Random Phase Approximation (RPA).

Investigating Dark Energy Equation of State With High Redshift Hubble Diagram

Frontiers in Astronomy and Space Sciences, 2020
Several independent cosmological data, collected within the last 20 years, revealed the accelerated expansion rate of the Universe, usually assumed to be driven by the so called dark energy, which, according to recent estimates, provides now about 70% of

Connecting mean-field theory with dynamo simulations

Living Reviews in Solar Physics
Mean-field dynamo theory, describing the evolution of large-scale magnetic fields, has been the mainstay of theoretical interpretation of magnetism in astrophysical objects such as the Sun for several decades.

Fast and effective methods for pattern mining in complex data [PDF]

Among today's challenges in big data science, called the "Big V's", variety induces an enormous complexity of data. A vast number of portable or stationary devices collect sensor or user information of various types. In medicine, diagnostic tools observe

The ELBA force field for coarse-grain modeling of lipid membranes.

PLoS ONE, 2011
A new coarse-grain model for molecular dynamics simulation of lipid membranes is presented. Following a simple and conventional approach, lipid molecules are modeled by spherical sites, each representing a group of several atoms.

Neural analysis of seismic data: applications to the monitoring of Mt. Vesuvius

Annals of Geophysics, 2013
The computing techniques currently available for the seismic monitoring allow advanced analysis. However, the correct event classification remains a critical aspect for the reliability of real time automatic analysis.
