Role of inhomogeneities in the flattening of the quantum effective potential
Gergely Endrődi, Tamás G. Kovács, Gergely Markó
We investigate the role of inhomogeneous field configurations in systems with a spontaneously broken continuous global symmetry. Spontaneous breaking is usually defined as a specif…
Dynamics of Haumea's dust ring
Tamás Kovács, Zsolt Regály
The particle dynamics of the recently observed ring around dwarf planet Haumea is numerically investigated. The point mass gravitational force, a second degree and order gravity fi…
HAT-P-65b and HAT-P-66b: Two Transiting Inflated Hot Jupiters and Observational Evidence for the Re-Inflation of Close-In Giant Planets
Joel D. Hartman, Gáspár Á. Bakos, Waqas Bhatti +25
We present the discovery of the transiting exoplanets HAT-P-65b and HAT-P-66b, with orbital periods of 2.6055 d and 2.9721 d, masses of M and $0.783 \pm 0.0…
Multi-wavelength study of the low-luminosity outbursting young star HBC 722
Á. Kóspál, P. Ábrahám, J. A. Acosta-Pulido +22
HBC 722 (V2493 Cyg) is a young eruptive star in outburst since 2010. It is an FU Orionis-type object with an atypically low outburst luminosity. Because it was well characterized i…
HAT-P-47b AND HAT-P-48b: Two Low Density Sub-Saturn-Mass Transiting Planets on the Edge of the Period--Mass Desert
G. Á. Bakos, J. D. Hartman, G. Torres +21
We report the discovery of two new transiting extrasolar planets orbiting moderately bright (V = 10.7 and 12.2 mag) F stars (masses of 1.39 Msun and 1.10 Msun, respectively). The p…
Overtone and multi-mode RR Lyrae stars in the globular cluster M3
J. Jurcsik, P. Smitola, G. Hajdu +15
The overtone and multi-mode RR Lyrae stars in the globular cluster M3 are studied using a 200-d long, and time-series photometry obtained in 2012. 70\% of the…
HAT-P-50b, HAT-P-51b, HAT-P-52b, and HAT-P-53b: Three Transiting Hot Jupiters and a Transiting Hot Saturn From the HATNet Survey
Joel D. Hartman, Waqas Bhatti, Gáspár Á. Bakos +26
We report the discovery and characterization of four transiting exoplanets by the HATNet survey. The planet HAT-P-50b has a mass of 1.35 M_J and a radius of 1.29 R_J, and orbits a…
Control of chaos in the vicinity of the Earth--Moon L5 Lagrangian point to keep a spacecraft in orbit
Judit Slíz, Áron Süli, Tamás Kovács
The concept of Space Manifold Dynamics is a new method of space research. We have applied it along with the basic idea of the method of Ott, Grebogi and York (OGY method) to stabil…
HAT-P-54b: A hot jupiter transiting a 0.64 Msun star in field 0 of the K2 mission
G. Á. Bakos, J. D. Hartman, W. Bhatti +22
We report the discovery of HAT-P-54b, a planet transiting a late K dwarf star in field 0 of the NASA K2 mission. We combine ground-based photometric light curves with radial veloci…
Quark localization in QCD above
Matteo Giordano, Tamás G. Kovács, Ferenc Pittler
It was previously found that at high temperature the lowest part of the QCD Dirac spectrum consists of localized modes obeying Poisson statistics. Higher up in the spectrum, modes…
Testing SNe Ia distance measurement methods with SN 2011fe
J. Vinko, K. Sarneczky, K. Takats +17
The nearby, bright, almost completely unreddened Type Ia supernova 2011fe in M101 provides a unique opportunity to test both the precision and the accuracy of the extragalactic dis…
Comprehensive time series analysis of the transiting extrasolar planet WASP-33b
G. Kovács, T. Kovács, J. D. Hartman +6
HD 15082 (WASP-33) is the hottest and fastest rotating star known to harbor a transiting extrasolar planet (WASP-33b). The lack of high precision radial velocity (RV) data stresses…
Anderson localization through Polyakov loops: lattice evidence and Random matrix model
Falk Bruckmann, Tamás G. Kovács, Sebastian Schierenberg
We investigate low-lying fermion modes in SU(2) gauge theory at temperatures above the phase transition. Both staggered and overlap spectra reveal transitions from chaotic (random…
Vortices and confinement
T. G. Kovács, E. T. Tomboulis
We review recent developments in the vortex picture of confinement. We discuss numerical simulations demonstrating that the entire asymptotic string tension is due to vortex-induce…
SO(3) vortices and disorder in the 2d SU(2) chiral model
Tamás G. Kovács, E. T. Tomboulis
We study the correlation function of the 2d SU(2) principal chiral model on the lattice. By rewriting the model in terms of Z(2) degrees of freedom coupled to SO(3) vortices we sho…
