Morphology evolution of vegetation-covered loess gully heads induced by hydraulic and gravitational erosion

open access: yesInternational Soil and Water Conservation Research
Gully heads suffer hydraulic and gravitational erosion triggered by rainstorms. However, how hydraulic and gravitational erosion affect the morphology evolution of the vegetation-covered loess gully heads is unclear.

Nonequilibrium thermodynamics of gravitational objective-collapse models

open access: yesPhysical Review Research
We investigate the entropy production in the Diósi-Penrose (DP) model, one of the most extensively studied gravity-related collapse mechanisms, and one of its dissipative extensions.

Quantum correlations in a gravitational collapse simulation with SpheriCo.jl

open access: yesJournal of High Energy Physics
We report on work using a newly developed code, SpheriCo.jl, that computes the gravitational collapse of a spherical scalar field, where the scalar can be either a classical field, or a quantum field operator.

Gravitational collapse in energy-momentum squared gravity: Nature of singularities

open access: yesNuclear Physics B
In this paper we explore a collapsing scenario in the background of energy-momentum squared gravity (EMSG). EMSG claims to have terms that originate from the quantum gravity effects mimicking loop quantum gravity.

Gravitational collapse in pure Gauss–Bonnet theory

open access: yesEuropean Physical Journal C: Particles and Fields
In this paper, we study the gravitational collapse of matter fields, which include dust, perfect fluids as well as fluids admitting bulk and shear viscosity.

Non-singular gravitational collapse through modified Heisenberg algebra

open access: yesEuropean Physical Journal C: Particles and Fields
We study the effects of cut-off physics, in the form of a modified algebra inspired by Polymer Quantum Mechanics and by the Generalized Uncertainty Principle representation, on the collapse of a spherical dust cloud.

Primordial black holes at the junction

open access: yesJournal of High Energy Physics
Primordial black holes (PBHs) formed during first-order phase transitions provide a powerful link between the early-universe microphysics and observable signatures today, including dark matter and gravitational waves.
