Resonances in coupled πK-ηK scattering from quantum chromodynamics. [PDF]
Physical Review Letters, 2014 Using a first-principles calculation within quantum chromodynamics, we are able to determine a pattern of strangeness=1 resonances that appear as complex singularities within coupled πK-ηK scattering amplitudes.

Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field
Advances 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.

Understanding the proton mass in QCD
SciPost 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

Entropy in quantum chromodynamics
, 2012 We review the role of zero-temperature entropy in several closely-related contexts in QCD. The first is entropy associated with disordered condensates, including $$. The second is vacuum entropy arising from QCD solitons such as center vortices, yielding

The Three Loop Two-Mass Contribution to the Gluon Vacuum Polarization [PDF]
, 2017 We calculate the two-mass contribution to the 3-loop vacuum polarization of the gluon in Quantum Chromodynamics at virtuality $p^2 = 0$ for general masses and also present the analogous result for the photon in Quantum Electrodynamics.Comment: 5 pages ...

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.

Round table: What can we learn about confinement and anoma-lous effects in QCD using analog systems?
EPJ Web of Conferences, 2017 We discuss an number of examples for recent connections between emergent phenomena in many-body systems in atomic and condensed matter physics, and confinement and other non-perturbative phenomena in quantum chromodynamics.

Cosmological Phase Transitions—EWPT-QCDPT: Magnetic Field Creation
Magnetochemistry, 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.

Anderson transition and multifractals in the spectrum of the Dirac operator of Quantum Chromodynamics at high temperature [PDF]
, 2015 We investigate the Anderson transition found in the spectrum of the Dirac operator of quantum chromodynamics at high temperature, studying the properties of the critical quark eigenfunctions.
