Finite temperature fermionic condensate and energy–momentum tensor in cosmic string spacetime
Published 2024-10-01“…Abstract Here we analyze the expectation value of the fermionic condensate and the energy–momentum tensor associated with a massive charged fermionic quantum field with a nonzero chemical potential propagating in a magnetic-flux-carrying cosmic string in thermal equilibrium at finite temperature T. …”

Revisiting the fermion-field nontopological solitons
Published 2024-09-01“…This study establishes a general framework for calculating fermionic soliton profiles under arbitrary scalar potentials, utilizing relativistic mean field theory to accurately depict the interaction between the fermion condensate and the background scalar field. Within this framework, the conventional “fermion bound states” are revealed as a subset of fermionic solitons. …”

Grassmann tensor renormalization group approach to (1+1)-dimensional two-color lattice QCD at finite density
Published 2025-03-01“…The Grassmann bond-weighted tensor renormalization group approach is adopted to evaluate the quark number density, fermion condensate, and diquark condensate at different gauge couplings as a function of the chemical potential. …”

Plasmon Mediation of Charge Pairing in High Temperature Superconductors
Published 2021-01-01“…We demonstrated that the quantum coherence of the two-component BEC (boson and fermion condensates) is controlled by plasmons. It has been proposed that plasmons, observed in both electron-doped and hole-doped cuprates, originates from the long-range Coulomb screening, where the transfer momentum q⟶0. …”
