Critical value of symmetry breaking parameter in the phase transition of decay rate
Hungsoo Kim, Soo-Young Lee, Sahng-Kyoon Yoo +2
Phase transition of decay rate from quantum tunneling to thermal activity regimes is investigated in (3+1)-dimensional field theories with symmetry breaking term . By applying…
Lagrangian Approach of the First Class Constrained Systems
Yong-Wan Kim, Seung-Kook Kim, Young-Jai Park
We show how to systematically derive the exact form of local symmetries for the abelian Proca and CS models, which are converted into first class constrained systems by the BFT for…
Two different gauge-invariant models in the Lagrangian approach
Seung-Kook Kim, Yong-Wan Kim, Young-Jai Park
We show how to systematically derive the complete set of the gauge transformations of different types of the gauge invariant models, which are the chiral Schwinger and CP with…
Double-Well Potential : The WKB Approximation with Phase Loss and Anharmonicity Effect
Chang Soo Park, Myung Geun Jeong, Sahng-Kyoon Yoo +1
We derive a general WKB energy splitting formula in a double-well potential by incorporating both phase loss and anharmonicity effect in the usual WKB approximation. A bare applica…
