Equivalence of renormalization with self-adjoint extension in Green's function formalism
D. K. Park, Sahng-Kyoon Yoo
Energy-dependent Green's functions for the two and three dimensional -function plus harmonic oscillator potential systems are derived by incorporating the renormalization and th…
The Second Virial Coefficient of Spin-1/2 Anyon Systems
Sahng-kyoon Yoo, D. K. Park
We calculate the second virial coefficient of spin-1/2 anyon gas in the various values of the self-adjoint extension parameter by incorporating the self-adjoint extension method in…
The incident wave in Aharonov-Bohm scattering wavefunction
Sahng-Kyoon Yoo, D. K. Park
It is shown that only the infinite angular momentum quantum states contribute to the incident wave in Aharonov-Bohm (AB) scattering. This result is clearly shown by recalculating t…
Comment on prescription problem in light-cone gauge
D. K. Park
Recently suggested causal principal value and causal prescriptions for the "spurious singularity" in light-cone gauge theories are nothing but the different guises of usual Mandels…
New prescription in light-cone gauge theories
D. K. Park
New prescription for the singularities of light-cone gauge theories is suggested. The new prescription provides Green's function which is identical with and different from that of…
