Sajti, Szilárd Mihály, 2024, "Calculation of bivariate cylindrically symmetric α-stable distribution using Wynn’s ε-method. Generated datasets.", https://hdl.handle.net/21.15109/ARP/BIPBSA, ARP, V1
The α-stable distributions appear in a broad field. We needed them in X-ray and neutron off-specular scattering, where their characteristic functions are frequently used as correlation functions. In practice, we need the Fourier-transforms of the 2-dimensional (and usually cylindrically symmetric) correlation functions, i.e. the corresponding proba... |
Szilágyi, Edit; Pal, Manoj Kumar; Kótai, Endre; Zolnai, Zsolt; Bányász, István, 2024, "Fluence evolution of defects in α-SiO2 determined by ionoluminescence", https://hdl.handle.net/21.15109/CONCORDA/N6ODFL, ARP, V1
Luminescence is a very powerful tool to analyse various types of defects in a wide range of materials; it is often applied for silica, which is a broadly used material in photonics, microelectronics, nuclear energy industry, optoelectronics and other important technological applications. In this work, a single crystalline (0001) α-SiO2 (quartz) sam... |
Himics, László; Gál, Dávid; Csíkvári, Péter; Holomb, Roman; Koós, Margit; Sulyok, Attila; Pécz, Béla; Veres, Miklós, 2024, "A modified plasma immersed solid-phase impurity assisted doping geometry for the creation of highly fluorescent CVD nanodiamond", https://hdl.handle.net/21.15109/CONCORDA/YBGOAE, ARP, V1
In this work, we report on a simple and easy to realize doping geometry by which the color center formation efficiency can be improved significantly in nanocrystalline diamond structures during solid impurity source-assisted microwave plasma enhanced chemical vapor deposition (MWCVD). A vertically aligned solid impurity source immersed into the CVD... |

Timár, Anikó; Németh, Zoltán; Opitz, Andrea, 2023, "Rosetta solar wind dynamic pressure proxy", https://hdl.handle.net/21.15109/CONCORDA/D6Z1YA, ARP, V1
Rosetta solar wind dynamic pressure proxy for the time interval when the Rosetta spacecraft was located deep inside the magnetosphere of Comet 67P, between April 2015 and February 2016, calculated from Rosetta RPC MAG measurements. |

Vértesi, Róbert; Bencédi, Gyula; Misák, Anett; Ortiz, Antonio, 2023, "Probing the interaction of semi-hard quarks and gluons with the underlying event in light- and heavy-flavor triggered proton-proton collisions", https://hdl.handle.net/21.15109/CONCORDA/JXMMU2, ARP, V1
We study underlying-event observables in inelastic proton-proton (pp) collisions at a centre-of-mass energy of √s = 13 TeV with identified light and heavy-flavor triggers using the PYTHIA 8 event generator. The study is performed as a function of the transverse momentum of the leading particle (pTtrigger). While at high pTtrigger (>10 GeV/c) the un... |

Éva; Kováts, Éva; Németh, Zoltán; Bogdán, Csilla; Bazsó, Gábor; Rozgonyi, Tamás; Vankó, György, 2023, "Molecular Engineering to Tune Functionality: The Case of Cl-Substituted [Fe(terpy)2]2+", https://hdl.handle.net/21.15109/CONCORDA/VF4I94, ARP, V1
The properties of transition-metal complexes and their chemical dynamics can be effectively modified with ligand substitutions, and theory can be a great aid to such molecular engineering. In this paper, we first theoretically explored how substitution with a Cl atom at different positions of the terpyridine ligand affects the electronic structure... |

Takátsy, János; Kovács, Péter; Wolf, György; Schaffner-Bielich, Juergen, 2023, "What neutron stars tell about the hadron-quark phase transition: A Bayesian study", https://hdl.handle.net/21.15109/CONCORDA/O5XS5A, ARP, V1
The existence of quark matter inside the heaviest neutron stars has been the topic of numerous recent studies, many of them suggesting that a phase transition to strongly interacting conformal matter inside neutron stars is feasible. Here we examine this hybrid star scenario using a soft and a stiff hadronic model, a constituent quark model with th... |

Rátkai, László; Szállás, Attila; Pusztai, Tamás; Mohri, Tetsuo; Gránásy, László, 2023, "Ternary eutectic dendrites: Pattern formation and scaling properties", https://hdl.handle.net/21.15109/CONCORDA/CJXEB4, ARP, V1
Extending previous work [Pusztai et al., Phys. Rev. E 87, 032401 (2013)], we have studied the formation of eutectic dendrites in a model ternary system within the framework of the phase-field theory. We have mapped out the domain in which two-phase dendritic structures grow. With increasing pulling velocity, the following sequence of growth morphol... |

Szigeti, Balázs Endre; Barna, Imre Ferenc; Barnaföldi, Gergely Gábor, 2023, "The Formulation of Scaling Expansion in an Euler-Poisson Dark-Fluid Model", https://hdl.handle.net/21.15109/CONCORDA/VJSOOI, ARP, V1
We present a dark fluid model described as a non-viscous, non-relativistic, rotating, and self-gravitating fluid. We assume that the system has spherical symmetry and that the matter can be described by the polytropic equation of state. The induced coupled nonlinear partial differential system of equations was solved using a self-similar time-depen... |

A micropattern and wire chamber hybrid has been constructed for UV photon detection, and its performance evaluated. It is revealed that such combination retains some key advantages of both the Thick-GEM primary and CCC secondary amplification stages, and results in a high gain gaseous photon detector with outstanding stability. Key features such as... |
