de Sitter Excited State in Heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ Theory

Fortschritte der Physik, EarlyView.
Abstract A novel duality sequence is devised to study late‐time cosmology in the heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ setup of Horava and Witten with dynamical walls that are moving towards each other. Remarkably, the dimensionally reduced 4‐dimensional theory does not violate NEC and no bouncing or ekpyrotic phase is observed.

The DNA of Calabi–Yau Hypersurfaces

Fortschritte der Physik, EarlyView.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Cosmological analogies for geophysical flows, Lagrangians, and new analogue gravity systems

European Physical Journal C: Particles and Fields, 2023
Formal analogies between the ordinary differential equations describing geophysical flows and Friedmann cosmology are developed. As a result, one obtains Lagrangian and Hamiltonian formulations of these equations, while laboratory experiments aimed at ...

Quantum Iterative Methods for Solving Differential Equations with Application to Computational Fluid Dynamics

Advanced Quantum Technologies, EarlyView.
Quantum algorithms for differential equations are developed with applications in computational fluid dynamics. The methods follow an iterative simulation framework, implementing Jacobi and Gauss–Seidel schemes on quantum registers through linear combinations of unitaries.

Lectures on string theory and cosmology

, 2004
In these lectures I review recent attempts to apply string theory to cosmology, including string cosmology and various models of brane cosmology. In addition, the review includes an introduction to inflation as well as a discussion of transplanckian ...

Exposing and Challenging “Grit” in Physics Education

Science Education, EarlyView.
ABSTRACT In STEM education, grit is increasingly the focus of research, with scholars and educators seeking to develop and test interventions that will enhance persistence. As part of the special issue Centering Affect and Emotion Toward Justice and Dignity in Science Education, in this paper, we use interviews with 12 white physics faculty to show ...

Plaints soient les Indiens du cosmos

Revue d'anthropologie des connaissances, 2018
While since the late 1960s, Americans draw in the Native American culture hoping to give a sense of their life back in a materialist society, the NASA space programme reflects a cosmology and an ethos injuring Zuni cosmology.

Network Cosmology

, 2012
Prediction and control of the dynamics of complex networks is a central problem in network science. Structural and dynamical similarities of different real networks suggest that some universal laws might accurately describe the dynamics of these networks,
