Analytical study of holographic superconductor with backreaction in 4d Gauss-Bonnet gravity

open access: yesPhysics Letters B, 2021
In this paper we have analytically investigated holographic superconductors in four dimensional Einstein-Gauss-Bonnet gravity background. Recently the novel four dimensional Einstein-Gauss-Bonnet gravity has been formulated by rescaling the Gauss-Bonnet ...

AdS/BCFT and Island for curvature-squared gravity

open access: yesJournal of High Energy Physics, 2022
In this paper, we investigate AdS/BCFT for curvature-squared gravity. To warm up, we start with Gauss-Bonnet gravity. We derive the one point function of stress tensor and show that the central charge related to the norm of displacement operator is ...

On a Surface Associated to the Catalan Triangle

open access: yesAxioms, 2022
We define a surface that interpolates the ballot numbers in the Catalan triangle corresponding to every pair of nonnegative integers (except for the origin).

Curvatures of hypersurfaces

open access: yesLietuvos Matematikos Rinkinys, 2010
In this article we generalize some classical formulas for curvatures of hypersurfaces in the n-dimensional Euclidean space using the homogeneous formulas.

Holographic superconductors in 4D Einstein-Gauss-Bonnet gravity with backreactions

open access: yesPhysics Letters B, 2021
We construct the holographic superconductors away from the probe limit in the consistent D→4 Einstein-Gauss-Bonnet gravity. We observe that, both for the ground state and excited states, the critical temperature first decreases then increases as the ...

Horndeski gravity as D → 4 limit of Gauss-Bonnet

open access: yesPhysics Letters B, 2020
We propose a procedure for the D→4 limit of Einstein-Gauss-Bonnet (EGB) gravity that leads to a well defined action principle in four dimensions. Our construction is based on compactifying D-dimensional EGB gravity on a (D−4)-dimensional maximally ...

Curvature-driven instabilities in thin active shells

open access: yesRoyal Society Open Science, 2022
Spontaneous material shape changes, such as swelling, growth or thermal expansion, can be used to trigger dramatic elastic instabilities in thin shells.

The Gauss Map of Complete Minimal Surfaces with Finite Total Curvature

open access: yesAnais da Academia Brasileira de Ciências, 2013
In this paper we are concerned with the image of the normal Gauss map of a minimal surface immersed in ℝ3 with finite total curvature. We give a different proof of the following theorem of R.

A New Approach to Rotational Weingarten Surfaces

open access: yesMathematics, 2022
Weingarten surfaces are those whose principal curvatures satisfy a functional relation, whose set of solutions is called the curvature diagram or the W-diagram of the surface.

Swimming in Curved Surfaces and Gauss Curvature

open access: yesUniversitas Scientiarum, 2018
The Cartesian-Newtonian paradigm of mechanics establishes that, within an inertial frame, a body either remains at rest or moves uniformly on a line, unless a force acts externally upon it.
