Warped super-bigravity
Zygmunt Lalak, Radoslaw Matyszkiewicz
Warped supergravities with lower-dimensional branes provide consistent field-theoretic framework for discussion of important aspects of modern string theory physics. In particular,…
Brane world supersymmetry, detuning, flipping and orbifolding
Philippe Brax, Zygmunt Lalak
We emphasize the necessity of a delicate interplay between the gauge and gravitational sectors of five-dimensional brane worlds in creating phenomenologically relevant vacua. We di…
Backreactions in Superinflationary Cosmologies
Z. Lalak, R. Poppe
We examine Jordan-Brans-Dicke theories with a linear potential for the scalar field by means of a stochastic approach. The backreaction of the scalar field fluctuations on the clas…
Towards a Solution of the Cosmological Domain Walls Problem
Zygmunt Lalak
We show that all kinds of biasing of cosmological phase transitions produce qualitatively new type of domain wall networks. The biased networks consist of compact, finite size, bag…
Non-Equilibrium Phase Transitions and Domain Walls
D. Coulson, Z. Lalak, B. Ovrut
Non-equilibrium phase transitions of a scalar field in an expanding spacetime are discussed. These transitions are shown to lead, for appropriate potential energy functions, to a b…
Phase Transitions in NJL and super-NJL models
Z. Lalak, J. Pawelczyk, S. Pokorski
An elementary method of determination of the character of the hot phase transition in 4d four-fermion NJL-type models is applied to non-supersymmetric and supersymmetric versions o…
