Stability of the de-Sitter spacetime. The anisotropic case
Przemysław Bieniek, Jan Chojnacki, Jan H. Kwapisz +1
We elaborate on the cosmological implications of the recently established non-perturbative )-symmetric approach. Following the -complete Friedmann equations, we provide…
Stability of the non-perturbative de-Sitter spacetime. The isotropic case
Przemysław Bieniek, Jan Chojnacki, Jan H. Kwapisz +1
The existence of de-Sitter solutions and their stability within string theory became, in recent years, one of the central research questions within the string theory community. The…
Grand unification and the Planck scale: An example of radiative symmetry breaking
Aaron Held, Jan Kwapisz, Lohan Sartore
Grand unification of gauge couplings and fermionic representations remains an appealing proposal to explain the seemingly coincidental structure of the Standard Model. However, to…
The weak-gravity bound in asymptotically safe gravity-gauge systems
Astrid Eichhorn, Jan Henryk Kwapisz, Marc Schiffer
The weak-gravity bound has been discovered in asymptotically safe gravity-matter systems, where it limits the maximum strength of gravitational fluctuations. In the present paper,…
Finite Action Principle and wormholes
Jan Chojnacki, Jan Henryk Kwapisz
In this work, we elaborate on the finite action for wormholes in higher derivative theories. Both non-traversable and traversable wormholes in theories with higher curvature invari…
Stability of domain walls in models with asymmetric potentials
Tomasz Krajewski, Jan Henryk Kwapisz, Zygmunt Lalak +1
We study the evolution of cosmological domain walls in models with asymmetric potentials. Our research goes beyond the standard case of spontaneous breaking of an approximate symme…
Finite Action Principle and Horava-Lifshitz Gravity: early universe, black holes and wormholes
Jan Chojnacki, Jan H. Kwapisz
The destructive interference of the neighbouring field configurations with infinite classical action in the gravitational path integral approach serves as a dynamical mechanism res…
Is asymptotically safe inflation eternal?
Jan Chojnacki, Julia Krajecka, Jan H. Kwapisz +2
Recently, based on swampland considerations in string theory, the (no) eternal inflation principle has been put forward. The natural question arises whether similar conditions hold…
Asymptotic safety and quantum gravity amplitudes
Jan H. Kwapisz, Krzysztof A. Meissner
Application of the Weinberg's conditions of asymptotic safety to amplitudes and not to couplings of the effective action can help to uniquely define the running in the UV and avoid…
Conformal standard model and inflation
Jan Henryk Kwapisz
This thesis presents a possible inflation scenario as a consequence of non-minimal gravitational couplings in the Conformal Standard Model. That model consists, in comparison to th…
Asymptotic safety of gravity, the Higgs boson mass and beyond the Standard Model physics
Jan H. Kwapisz
There are many hints that gravity is asymptotically safe. The inclusion of gravitational corrections can result in the ultraviolet fundamental Standard Model and constrain the Higg…
Asymptotic safety and Conformal Standard Model
Frederic Grabowski, Jan H. Kwapisz, Krzysztof A. Meissner
We show that the Conformal Standard Model supplemented with asymptotically safe gravity can be valid up to arbitrarily high energies and give a complete description of particle phy…
Conformal Standard Model and Inflation
Jan Kwapisz, Krzysztof A. Meissner
This article presents a possible inflation scenario as a consequence of non-minimal gravitational couplings in the Conformal Standard Model. The model consists, in comparison to th…
Applications of Hückel-Su-Schrieer-Heeger method. I. Carbon-carbon bond lengths in polycyclic aromatic hydrocarbons
Jan Kwapisz, Leszek Z. Stolarczyk
The equilibrium carbon-carbon bond lengths in -electron hydrocarbons are very sensitive to the electronic ground-state characteristic. In the recent two papers by Stolarczyk and…
Renormalization group procedure for potential
Sebastian M. Dawid, Rafał Gonsior, Jan Kwapisz +3
Schrödinger equation with potential exhibits a limit cycle, described in the literature in a broad range of contexts using various regularizations of the singularity at $r…
