Searching Extra Dimensions in Compact Stars
G. G. Barnafoldi, P. Levai, B. Lukacs
The electro-magnetic and particle radiation detected from the direction of Cygnus X3 raise the question of the existence of special long-lived, neutral particles. We investigate th…
On a Possible Indicator of Homogeneity of the Universe
Nora Fay, B. Lukacs
A new method is described for recognising internal non-randomness in deep galaxy surveys.
The inner structure of hybrid stars
B. Lukacs, G. G. Barnafoldi, P. Levai
Hybrid stars with extremely high central energy density in their core are natural laboratories to investigate the appearance and the properties of compactified extra dimensions wit…
Heavy quarks or compactified extra dimensions in the core of hybrid stars
G. G. Barnafoldi, P. Levai, B. Lukacs
Neutron stars with extremely high central energy density are natural laboratories to investigate the appearance and the properties of compactified extra dimensions with small compa…
Simple solutions of fireball hydrodynamics for self-similar elliptic flows
S. V. Akkelin, T. Csorgo, B. Lukacs +2
Simple, self-similar, elliptic solutions of non-relativistic fireball hydrodynamics are presented, generalizing earlier results for spherically symmetric fireballs with Hubble flow…
New analytic solutions of the non-relativistic hydrodynamical equations
P. Csizmadia, T. Csorgo, B. Lukacs
New solutions are found for the non-relativistic hydrodynamical equations. These solutions describe expanding matter with a Gaussian density profile. In the simplest case, thermal…
Thermodynamic Length, Time, Speed and Optimum Path to Minimize Entropy Production
L. Diosi, K. Kulacsy, B. Lukacs +1
In addition to the Riemannian metricization of the thermodynamic state space, local relaxation times offer a natural time scale, too. Generalizing existing proposals, we relate {\i…
Critique of proposed limit to space--time measurement, based on Wigner's clocks and mirrors
Lajos Diosi, B. Lukacs
Based on a relation between inertial time intervals and the Riemannian curvature, we show that space--time uncertainty derived by Ng and van Dam implies absurd uncertainties of the…
Are There Top Quarks In Superdense Hybrid Stars?
M. Prisznyak, B. Lukacs, P. Levai
It is examined whether primordial top quarks from the Big Bang could survive under natural conditions till present days. Hybrid quark-neutron stars, with dense enough core to maint…
Calculation of X-Ray Signals from Karolyhazy Hazy Space-Time
L. Diosi, B. Lukacs
Karolyhazy's hazy space-time model, invented for breaking down macroscopic interferences, employs wave-like gravity disturbances. If so, then electric charges would radiate permane…
