Weyl discs: theoretical prediction
Janis Erdmanis, Árpád Lukács, Yuli V. Nazarov
A variety of quantum systems exhibits Weyl points in their spectra where two bands cross in a point of three-dimensional parameters space with conical dispersion in the vicinity of…
Small amplitude quasi-breathers and oscillons
Gyula Fodor, Péter Forgács, Zalán Horváth +1
Quasi-breathers (QB) are time-periodic solutions with weak spatial localization introduced in G. Fodor et al. in Phys. Rev. D. 74, 124003 (2006). QB's provide a simple description…
Negative radiation pressure exerted on kinks
Péter Forgács, Árpád Lukács, Tomasz Romańczukiewicz
The interaction of a kink and a monochromatic plane wave in one dimensional scalar field theories is studied. It is shown that in a large class of models the radiation pressure exe…
An analytic approach to the late ISW effect in a Lambda dominated universe
Viktor Czinner, Mátyás Vasúth, Árpád Lukács
The integrated Sachs-Wolfe (ISW) effect in a Lambda dominated universe can be an important factor in the evolution of cosmic microwave background fluctuations. With the inclusion o…
Covariant Linear Perturbations in a Concordance Model
Viktor Czinner, Mátyás Vasúth, Árpád Lukács +1
We present the complete solution of the first order metric and density perturbation equations in a spatially flat (K=0), Friedmann-Robertson-Walker (FRW) universe filled with press…
