Charged gravitational instantons: extra CP violation and charge quantisation in the Standard Model

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We argue that quantum electrodynamics combined with quantum gravity results in a new source of CP violation, anomalous non-conservation of chiral charge and quantisation of electric charge.

Calibration of Calorimetric Measurement in a Liquid Argon Time Projection Chamber

open access: yesInstruments, 2020
The liquid argon time projection chamber provides high-resolution event images and excellent calorimetric resolution for studying neutrino physics and searching for beyond-standard-model physics. In this article, we review the main physics processes that

Parameters for Systems Exhibiting Local Lattice Distortions, Charge and Spin Ordering [PDF]

open access: yes, 2000
Keeping in mind the experimental results that indicate local lattice distortions, charge and spin orderings, we have developed a phenomenological approach which allows us to describe the electronic phase diagram of cuprates and related systems in terms ...

Geospace: The naturally occurring plasma laboratory

open access: yesFrontiers in Astronomy and Space Sciences, 2022
While the societal relevance of space physics drives most of the research in the field, this paper argues for the merit in addressing problems that are core to plasma physics, regardless of discipline or application to society.

The PANDORA project: an experimental setup for measuring in-plasma β-decays of astrophysical interest [PDF]

open access: yesEPJ Web of Conferences, 2020
Experiments performed on Storage Rings have shown that lifetimes of beta-radionuclides can change dramatically as a function of theionization state. PANDORA (Plasmas for Astrophysics, Nuclear Decay Observation and Radiation for Archaeometry) aims at ...

Conformal collider physics at large charge

open access: yesJournal of High Energy Physics
We study energy correlators and other event shapes in states created by operators with large global U(1) charge Q in Conformal Field Theories. Focusing on theories whose large charge sector is described by the superfluid Effective Field Theory (EFT), we ...

Excited nucleon electromagnetic form factors from broken spin-flavor symmetry

open access: yes, 2010
A group theoretical derivation of a relation between the N --> Delta charge quadrupole transition and neutron charge form factors is presented.Comment: 4 pages, Proc. of the 12 th Int'l. Workshop on the Physics of Excited Nucleons, NSTAR 2009, Beijing,

A quantum physics layer of epigenetics: a hypothesis deduced from charge transfer and chirality-induced spin selectivity of DNA

open access: yesClinical Epigenetics, 2023
Background Epigenetic mechanisms are informational cellular processes instructing normal and diseased phenotypes. They are associated with DNA but without altering the DNA sequence. Whereas chemical processes like DNA methylation or histone modifications

Hybrid Modeling of Lithium-Ion Battery: Physics-Informed Neural Network for Battery State Estimation

open access: yesBatteries, 2023
Accurate forecasting of the lifetime and degradation mechanisms of lithium-ion batteries is crucial for their optimization, management, and safety while preventing latent failures. However, the typical state estimations are challenging due to complex and

Charge Density Wave Ratchet

open access: yes, 1999
We propose to operate a locally-gated charge density wave as an electron pump. Applying an oscillating gate potential with frequency $f$ causes equally spaced plateaux in the sliding charge density wave current separated by $\Delta I=2eNf,$ where $N$ is ...
