Emergence and oscillation of cosmic space by joining M1-branes

This paper addresses the issue of how the oscillation of the universe between contraction and expansion branches is explained in the framework of a BIonic system by articulating M1-BIons, a pair of M1–anti-M1-branes.

Emergence and expansion of cosmic space as due to M0-branes

Recently, Padmanabhan (arXiv:1206.4916 [hep-th]) discussed that the difference between the number of degrees of freedom on the boundary surface and the number of degrees of freedom in a bulk region

Emergence and expansion of cosmic space in an accelerating BIon

We generalize the Padmanabhan (arXiv:1206.4916 [hep-th]) mechanism to an accelerating BIon and show that the difference between the number of degrees of freedom on the boundary surface and the number

The Flowing BIon

In this paper we use the effective blackfold description of branes to extend the study of the thermal BIon, a D-brane and parallel anti-D-brane connected by a wormhole with F-string charge in hot

The whipped inflation in BIon system

Recently, a class of large field inflaton potentials has been identified which begins with a power law potentials. In this model, initially relative fast roll lasting until a few e-folds in the

Holographic Cosmology from BIonic Solutions

In this paper, we will use a BIonic solution for analyzing the holographic cosmology. A BIonic solution is a configuration of a D3-brane and an anti-D3-brane connected by a wormhole, and holographic

Emergence of anti-F(R) gravity in type-IV bouncing cosmology as due to M0-brane

Recently, some authors considered the origin of a type-IV singular bounce in modified gravity and obtained the explicit form of F(R) which can produce this type of cosmology. In this paper, we show

The evolution of Brown–York quasilocal energy as due to evolution of Lovelock gravity in a system of M0-branes

Recently, it has been suggested in [S. Chakraborty and N. Dadhich, Brown–York quasilocal energy in Lanczos–Lovelock gravity and black hole horizons, J. High Energ. Phys. 12 (2015) 003.] that the



Emergence of Cosmic Space and the Generalized Holographic Equipartition

Recently, a novel idea about our expanding Universe was proposed by T. Padmanabhan [arXiv:1206.4916]. He suggested that the expansion of our Universe can be thought of as the emergence of space as

Friedmann equations from emergence of cosmic space

Padmanabhan [arXiv:1206.4916] argues that the cosmic acceleration can be understood from the perspective that spacetime dynamics is an emergence phenomena. By calculating the difference between the

Note on the emergence of cosmic space in modified gravities

Intrigued by the holographic principle, Padmanabhan recently proposed a novel idea, saying that our cosmic space is emergent as cosmic time progresses. In particular, the expansion rate of the

Friedmann equation and the emergence of cosmic space

A bstractIn this paper, we show that Padmanabhan’s conjecture for the emergence of cosmic space [arXiv:1206.4916] holds for the flat Friedmann-Robertson-Walker universe in Einstein gravity but does

Heating up the BIon

We propose a new method to consider D-brane probes in thermal backgrounds. The method builds on the recently developed blackfold approach to higher-dimensional black holes. While D-brane probes in

Wormholes in spacetime and their use for interstellar travel: A tool for teaching general relativity

Rapid interstellar travel by means of spacetime wormholes is described in a way that is useful for teaching elementary general relativity. The description touches base with Carl Sagan’s novel

M2-M5 blackfold funnels

A bstractWe analyze the basic M2-M5 intersection in the supergravity regime using the blackfold approach. This approach allows us to recover the 1/4-BPS self-dual string soliton solution of Howe,

General definition of gravitational tension

In this note we give a general definition of the gravitational tension in a given asymptotically translationally-invariant spatial direction of a space-time. The tension is defined via the extrinsic

Entropy of the self-dual string soliton

A bstractWe compute the entropy and the corresponding central charge of the selfdual string soliton in the supergravity regime using the blackfold description of the fully localized M2-M5
