Superselection rules, quantum error correction, and quantum chromodynamics

open access: yesJournal of High Energy Physics
We investigate the relationship between superselection rules and quantum error correcting codes. We demonstrate that the existence of a superselection rule implies the Knill-Laflamme condition in quantum error correction.

Understanding the proton mass in QCD

open access: yesSciPost Physics Proceedings, 2022
Understanding the proton mass in quantum chromodynamics (QCD) is a very important and current topic in hadronic physics. The decomposition (sum rule) of the proton mass is not unique, and different sum rules, which are related to the QCD energy-momentum

Light Hadron Masses and Decay Constants

open access: yes, 2010
The extraction of the light hadron spectrum from a first-principle Quantum Chromodynamics approach is a profound application for lattice simulations of Quantum Chromodynamics.

Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
We investigate tensor condensates and chiral condensates in the (2 + 1)‐flavor Nambu–Jona–Lasinio model at finite temperature and density in the presence of a strong magnetic field. The emergence of the tensor condensate is attributed to the four‐fermion interaction.

Cosmological Phase Transitions—EWPT-QCDPT: Magnetic Field Creation

open access: yesMagnetochemistry, 2022
We review the cosmic microwave background (CMBR) estimate of ordinary matter, dark matter and dark energy in the universe. Then, we review the cosmological electroweak (EWPT) and quantum chromodynamics (QCDPT) phase transitions.

$0^{++}$ scalar glueball in finite-width Gaussian sum rules [PDF]

open access: yes, 2010
Based on a semiclassical expansion for quantum chromodynamics in the instanton liquid background, the correlation function of the $0^{++}$ scalar glueball current is given, and the properties of the $0^{++}$ scalar glueball are studied in the framework ...

Heavy Quarkonium States With Baryonic Chemical Potential

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential. The binding energies of the quarkonium states has been obtained by using quasiparticle Debye mass which further depends on temperature and baryonic chemical potential (μb ...

Simulating one-dimensional quantum chromodynamics on a quantum computer: Real-time evolutions of tetra- and pentaquarks

open access: yesPhysical Review Research, 2023
Quantum chromodynamics (QCD)—the theory of quarks and gluons—has been studied for decades, but it is yet to be fully understood. A recent example is the prediction and experimental discovery of tetraquarks, which opened a new research field.

Bayesian time‐lapse full waveform inversion using Hamiltonian Monte Carlo

open access: yesGeophysical 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.

Antimatter Gravity and the Results of the ALPHA‐g Experiment

open access: yesAnnalen 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 ...
