Darboux transformations and hidden quadratic supersymmetry of the one-dimensional stationary Dirac equation
N. Debergh, A. A. Pecheritsin, B. F. Samsonov +1
A matricial Darboux operator intertwining two one-dimensional stationary Dirac Hamiltonians is constructed. This operator is such that the potential of the second Dirac Hamiltonian…
Global Derivation of the Fluctuation Determinant from Group Property of Time Evolution
H. Kleinert, B. Van den Bossche
The Van Vleck-Pauli-Morette fluctuation determinant is derived from the global group property of the time evolution amplitude in a continuous formulation of path integrals.
No Massless Pions in Nambu-Jona-Lasinio Model due to Chiral Fluctuations
H. Kleinert, B. Van den Bossche
In contrast to common belief, the chirally symmetric Nambu--Jona-Lasinio model does not contain massless pions, due to strong chiral fluctuations. Although quarks acquire spontaneo…
The 3-flavor A-scaled Nambu-Jona-Lasinio model
B. Van den Bossche
We review the so called A-scaled Nambu-Jona-Lasinio model both in the vacuum and at finite temperature and density in the case of three flavors. Starting from QCD and integrating o…
Scalar mesons nonet in a scaled effective Lagrangian
M. Jaminon, B. Van den Bossche
A scaled SU(3) Nambu - Jona-Lasinio Lagrangian is used to compute the mass of the nine scalar mesons in the vacuum and the mass of the gluball. It is shown that a suitable choice o…
