One-loop Noncommutative U(1) Gauge Theory from Bosonic Worldline Approach
Youngjai Kiem, Yeonjung Kim, Cheol Ryou +1
We develop a method to compute the one-loop effective action of noncommutative U(1) gauge theory based on the bosonic worldline formalism, and derive compact expressions for N-poin…
Interacting Open Wilson Lines in Noncommutative Field Theories
Y. Kiem, S. Lee, S. -J. Rey +1
In noncommutative field theories, it was known that one-loop effective action describes propagation of non-interacting open Wilson lines, obeying the flying dipole's relation. We s…
Anatomy of Two-Loop Effective Action in Noncommutative Field Theories
Y. Kiem, S. -S. Kim, S. -J. Rey +1
We compute, at two-loop order, one-particle-irreducible Green functions and effective action in noncommutative -theory for both planar (g=0, h=3) and nonplanar (g=1,…
Anatomy of One-Loop Effective Action in Noncommutative Scalar Field Theories
Youngjai Kiem, Soo-Jong Rey, Haru-Tada Sato +1
One-loop effective action of noncommutative scalar field theory with cubic self-interaction is studied. Utilizing worldline formulation, both planar and nonplanar part of the effec…
Open Wilson Lines and Generalized Star Product in Noncommutative Scalar Field Theories
Y. Kiem, S. -J. Rey, H. -T. Sato +1
Open Wilson line operators and generalized star product have been studied extensively in noncommutative gauge theories. We show that they also show up in noncommutative scalar fiel…
Noncommutative Q-balls
Youngjai Kiem, Chanju Kim, Yoonbai Kim
We obtain Q-ball solutions in noncommutative scalar field theory with a global U(1) invariance. The Q-ball solutions are shown to be classically and quantum mechanically stable. We…
