Quantum Monte Carlo study of high pressure solid molecular hydrogen

New Journal of Physics, 2013
We use the diffusion quantum Monte Carlo (DMC) method to calculate the ground-state phase diagram of solid molecular hydrogen and examine the stability of the most important insulating phases relative to metallic crystalline molecular hydrogen.

Static axion stars revisited

Frontiers in Astronomy and Space Sciences
We consider static solutions to the spherically symmetric Einstein-scalar field systems with an axion potential known as axion stars, originally described by Guerra et al., JCAP (2019, 09 (09)).

The role of pressure anisotropy on quark stars in gravity’s rainbow

European Physical Journal C: Particles and Fields
This work is seeking for the existence of stable quark stars (QSs) in the framework of a modified theory of gravity known as gravity’s rainbow. This modification comes from the fact that the geometry of spacetime depends on the energy of the test ...

Traveling spiral wave chimeras in coupled oscillator systems: emergence, dynamics, and transitions

New Journal of Physics, 2023
Systems of coupled nonlinear oscillators often exhibit states of partial synchrony in which some of the oscillators oscillate coherently while the rest remain incoherent.
