Bayesian time‐lapse full waveform inversion using Hamiltonian Monte Carlo

Geophysical Prospecting, Volume 72, Issue 9, Page 3381-3398, November 2024.
Abstract Time‐lapse images carry out important information about dynamic changes in Earth's interior, which can be inferred using different full waveform inversion schemes. The estimation process is performed by manipulating more than one seismic dataset, associated with the baseline and monitors surveys.

Running of the top quark mass at NNLO in QCD

Journal of High Energy Physics
The running of the top quark mass (m t) is probed at the next-to-next-to-leading order in quantum chromodynamics for the first time. The result is obtained by comparing calculations in the modified minimal subtraction ( $$\overline{{\text{MS ...

Antimatter Gravity and the Results of the ALPHA‐g Experiment

Annalen der Physik, Volume 536, Issue 7, July 2024.
The recent results of the ALPHA‐g experiment, which show gravitational attraction between antihydrogen atoms and the Earth, seem to undermine the success of repulsive‐gravity models in the cosmological field. Analyzing the theory of CPT gravity, two solutions are found that are consistent with the experimental results, while preserving the large‐scale ...

Three-Qubit Encoding in Ytterbium-171 Atoms for Simulating 1+1D Quantum Chromodynamics

PRX Quantum
Simulating nuclear matter described by quantum chromodynamics using quantum computers is notoriously inefficient because of the assortment of quark degrees of freedom such as matter/antimatter, flavor, color, and spin.

Cylindrically Symmetric Diffusion Model for Relativistic Heavy‐Ion Collisions

Annalen der Physik, Volume 536, Issue 5, May 2024.
To account for particle production in relativistic heavy‐ion collisions at the Large Hadron Collider, a relativistic diffusion model with cylindrical symmetry is derived from nonequilibrium–statistical considerations. It propagates an initial state based on quantum chromodynamics in time toward a thermal equilibrium limit.

Limits on Dark Photons, Scalars, and Axion‐Electromagnetodynamics with the ORGAN Experiment

Annalen der Physik, Volume 536, Issue 1, January 2024.
The nature of dark matter is one of the biggest mysteries in the Universe. ORGAN is an experiment which seeks to understand dark matter by figuring out what it is made of. In this article, the current sensitivity of ORGAN to various promising dark matter candidates is presented, and the future sensitivity is projected.

Advances in Searching for Galactic Axions with a Dielectric Haloscope (MADMAX)

Annalen der Physik, Volume 536, Issue 1, January 2024.
In this article the general concept of the MADMAX (Magnetized Disc and Mirror Axion experiment) is described. MADMAX is a dielectric haloscope aimed to detect dark matter axions. Recent updates of the magnet and the cryostat that will host different prototype radio frequency (RF) booster systems are presented.
