Diquark degrees of freedom in the EOS and the compactness of compact stars
J. E. Horvath, G. Lugones, J. A. de Freitas Pacheco
We discuss the role of diquarks in constructing models of compact stars. These approaches are compared to recent claims of highly compact X-ray and isolated sources.
The Holtsmark distribution of forces and its role in gravitational clustering
L. Pietronero, M. Bottaccio, R. Mohayaee +1
The evolution and the statistical properties of an infinite gravitating system represent an interesting and widely investigated subject of research. In cosmology, the standard appr…
Topological Shocks in Burgers Turbulence
J. Bec, R. Iturriaga, K. Khanin
The dynamics of the multi-dimensional randomly forced Burgers equation is studied in the limit of vanishing viscosity. It is shown both theoretically and numerically that the shock…
Algebraic approach to time-delay data analysis for LISA
S. V. Dhurandhar, K. Rajesh Nayak, J-Y. Vinet
Cancellation of laser frequency noise in interferometers is crucial for attaining the requisite sensitivity of the triangular 3-spacecraft LISA configuration. Raw laser noise is se…
Intermittency in two-dimensional Ekman-Navier-Stokes turbulence
G. Boffetta, A. Celani, S. Musacchio +1
We study the statistics of the vorticity field in two-dimensional Navier-Stokes turbulence with a linear Ekman friction. We show that the small-scale vorticity fluctuations are int…
Analysis of cancellation in two-dimensional magnetohydrodynamic turbulence
L. Sorriso-Valvo, V. Carbone, A. Noullez +3
A signed measure analysis of two-dimensional intermittent magnetohydrodynamic turbulence is presented. This kind of analysis is performed to characterize the scaling behavior of th…
