Probing phase transitions in the early universe with gravitational waves

open access: yes, 2022
Gravitational waves will be an important probe of physics beyond the Standard Model, as they would be produced at possible first order phase transitions in the early universe. I will discuss the characteristic spectrum of gravitational radiation ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

What happens when supercooling is terminated by curvature flipping of the effective potential?

open access: yesJournal of High Energy Physics
We explore the nature of a certain type of supercooled phase transition, where the supercooling is guaranteed to end due to the curvature of the finite-temperature effective potential at the origin experiencing a sign flip at some temperature.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Phase Transitions in the Early Universe: The Cosmology of Non-minimal Scalar Sectors

open access: yes, 2017
Light scalar fields such as axions and string moduli can play an important role in early-universe cosmology. However, many factors can significantly impact their late-time cosmological abundances.

Axionic domain walls at Pulsar Timing Arrays: QCD bias and particle friction

open access: yesJournal of High Energy Physics, 2023
The recent results from the Pulsar Timing Array (PTA) collaborations show the first evidence for the detection of a stochastic background of gravitational waves at the nHz frequencies.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Bubble-wall velocity in local thermal equilibrium: hydrodynamical simulations vs analytical treatment

open access: yesJournal of High Energy Physics
We perform real-time hydrodynamical simulations of the growth of bubbles formed during cosmological first-order phase transitions under the assumption of local thermal equilibrium.

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Vortex line nucleation of first-order phase transitions in early universe [PDF]

open access: yes, 2020
With nonabelian Gauge Theories apparently possessing an abelian projection, the first-order phase transitions in the early Ž . universe should proceed similarly to those in U 1 -symmetric field systems, where they are known to be nucleated by vortex ...
