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

Superselection rules, quantum error correction, and quantum chromodynamics
Journal of High Energy PhysicsWe 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.

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.

Quantum‐Classical Simulation of Quantum Field Theory by Quantum Circuit Learning
Annalen der Physik, Volume 537, Issue 6, June 2025.Quantum circuit learning is employed to simulate quantum field theories (QFTs). By integrating a minimal qubit configuration and low‐depth circuits, the approach predicts real‐time dynamics accurately. It effectively simulates complex phenomena such as quench and chiral dynamics in a model of quantum electrodynamics, aligning well with classical ...

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.

Heavy Quarkonium States With Baryonic Chemical Potential
Advances 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 ...

Quark Confinement Physics in Quantum Chromodynamics [PDF]
, 1999 We study abelian dominance and monopole condensation for the quark confinement physics using the lattice QCD simulations in the MA gauge. These phenomena are closely related to the dual superconductor picture of the QCD vacuum, and enable us to construct
