Fubini vacua as a classical de Sitter vacua
Farhang Loran
The Fubini's idea to introduce a fundamental scale of hadron phenomena by means of dilatation non-invariant vacuum state in the frame work of a scale invariant Lagrangian field the…
Non-linear Laplace equation, de Sitter vacua and information geometry
Farhang Loran
Three exact solutions say of massless scalar theories on Euclidean space, i.e. , and models are obtained which share similar properties. The info…
A Dynamical Approach to Gauge Fixing
F. Loran
We study gauge fixing in the generalized Gupta-Bleuler quantization. In this method physical states are defined to be simultaneous null eigenstates of a set of quantum invariants.…
On The Quantization Of Constraint Systems: A Lagrangian Approach
F. Loran
It is possible to introduce external time dependent back ground fields in the formulation of a system as fields whose dynamics can not be deduced from Euler Lagrange equations of m…
Gauge Fixing in the Chain by Chain Method
A Shirzad, F Loran
In a recent work we showed that for a Hamiltonian system with constraints, the set of constraints can be investigated in first and second class constraint chains. We show here that…
