Spinning primordial black holes from first order phase transition

open access: yesJournal of High Energy Physics
We conduct a novel study to obtain the initial spin of the primordial black holes created during a first-order phase transition due to delayed false vacuum decay.

Breathing in Plants and Chaos—Cosmic Tree Events in Cameroon and Beyond

open access: yesAnthropology of Consciousness, EarlyView.
ABSTRACT Contemporary practices of tapping into the wisdom of ancestral trees are described through three entangled recent events lived within the context of Bantu practices in Cameroon. In the three instances, the steered or chance encounters with high potency trees were serendipitous telling moments which brought something new to the horizon.

Volume Quantization with Flexible Singularities for Hexahedral Meshing

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

open access: yesComputer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

On black holes in string theory [PDF]

open access: yes, 2011
PhDThis thesis investigates black holes in string theory through string amplitudes and through gauge-gravity duality. The research presented in this thesis supports the claim that string theory is capable of a consistent quantum-mechanical description

Establishing Shape Correspondences: A Survey

open access: yesComputer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Stochastic Gravitational Wave Background from Primordial Black Holes

open access: yes, 2022
reservedOne of the biggest problems in modern cosmology is to assess the nature of dark matter. We propose Primordial Black Holes (PBHs) as a possible candidate and we investigate how this scenario can be probed with the Stochastic Gravitational Wave ...

Primordial Black Holes and Gravitational Waves in the U(1) B−L extended inert doublet model: a first-order phase transition perspective

open access: yesJournal of High Energy Physics
We conduct an analysis of a U(1) B−L extended inert doublet model and obtained the parameter space allowing strong first order phase transitions. We show that a large part of the parameter space can cause double first-order phase transitions.

Phong‐Rodrigues Extrinsic Vector‐Field Processing

open access: yesComputer Graphics Forum, EarlyView.
Abstract We introduce a new extrinsic discretization of tangent vector fields on triangle meshes that is continuous, with bounded derivatives that are continuous almost everywhere, supporting pointwise evaluation and integration of differential operators.

Braneworld black holes [PDF]

open access: yes, 2006
The braneworld paradigm provides an interesting framework within which to explore the possibility that our Universe lives in a fundamentally higher dimensional space- time.
