Attractors in hyperspace [PDF]

open access: yesTopological Methods in Nonlinear Analysis, 2016
Given a map $\Phi$ defined on bounded subsets of the (base) metric space $X$ and with bounded sets as its values, one can follow the orbits $A$, $\Phi(A)$, $\Phi^2(A)$, $\ldots$, of nonempty, closed, and bounded sets $A$ in $X$. This is the system $(\Phi, X)$.

Chaotic inflation limits for non-minimal models with a Starobinsky attractor [PDF]

open access: yes, 2014
We investigate inflationary attractor points by analyzing non-minimally coupled single field inflation models in two opposite limits; the `flat' limit in which the first derivative of the conformal factor is small and the `steep' limit, in which the ...

The phenomenon of temporary architecture – its background and potential [PDF]

open access: yesArchitecture Papers of the Faculty of Architecture and Design STU, 2020
The article focuses on temporary, non-permanent architecture whose relationship with time as its determining aspect often dominates over its fundamental relationship with space.

Revisiting non-Gaussianity from non-attractor inflation models [PDF]

open access: yes, 2018
Non-attractor inflation is known as the only single field inflationary scenario that can violate non-Gaussianity consistency relation with the Bunch-Davies vacuum state and generate large local non-Gaussianity.

An alternative attractor in gauged NJL inflation

open access: yes, 2017
We have investigated the attractor structure for the CMB fluctuations in composite inflation scenario within the gauged Nambu-Jona-Lasinio (NJL) model. Such composite inflation represents an attractor which can not be found in a fundamental scalar model.

Non-Supersymmetric Attractors in BI black holes [PDF]

open access: yes, 2006
We study attractor mechanism in extremal black holes of Einstein-Born-Infeld theories in four dimensions. We look for solutions which are regular near the horizon and show that they exist and enjoy the attractor behavior.

Quantifying the Landscape of Decision Making From Spiking Neural Networks

open access: yesFrontiers in Computational Neuroscience, 2021
The decision making function is governed by the complex coupled neural circuit in the brain. The underlying energy landscape provides a global picture for the dynamics of the neural decision making system and has been described extensively in the ...

Homoclinic orbit and hidden attractor in the Lorenz-like system describing the fluid convection motion in the rotating cavity

open access: yes, 2014
In this paper a Lorenz-like system, describing the process of rotating fluid convection, is considered. The present work demonstrates numerically that this system, also like the classical Lorenz system, possesses a homoclinic trajectory and a chaotic ...

Nonsupersymmetric attractors [PDF]

open access: yesPhysical Review D, 2005
We consider theories with gravity, gauge fields and scalars in four-dimensional asymptotically flat space-time. By studying the equations of motion directly we show that the attractor mechanism can work for non-supersymmetric extremal black holes. Two conditions are sufficient for this, they are conveniently stated in terms of an effective potential ...

On the uniqueness of supersymmetric attractors

open access: yesPhysics Letters B, 2015
In this paper we discuss the uniqueness of supersymmetric attractors in four dimensional N=2 supergravity theories coupled to n vector multiplets. We prove that for a given charge configuration the supersymmetry preserving axion free attractors are unique.
