Remarks on Inflation and Noncommutative Geometry
Chong-Sun Chu, Brian R. Greene, Gary Shiu
We briefly discuss some possible cosmological implications of noncommutative geometry. While the noncommutativity we consider does not affect gravity, it can play an important role…
String Theory and Noncommutative Field Theories at One Loop
Adel Bilal, Chong-Sun Chu, Rodolfo Russo
By exploiting the boundary state formalism we obtain the string correlator between two internal points on the one loop open string world-sheet in the presence of a constant backgro…
Induced Chern-Simons and WZW action in Noncommutative Spacetime
Chong-Sun Chu
We consider noncommutative gauge theory with Dirac or Majorana fermions in odd dimensional spacetime and compute the induced noncommutative Chern-Simons action generated at 1-loop.…
Multiloop String Amplitudes with B-Field and Noncommutative QFT
Chong-Sun Chu, Rodolfo Russo, Stefano Sciuto
The multiloop amplitudes for the bosonic string in presence of a constant B-field are built by using the basic commutation relations for the open string zero modes and oscillators.…
Testing the AdS/CFT correspondence beyond large N
Adel Bilal, Chong-Sun Chu
According to the AdS/CFT correspondence, the maximally supersymmetric SU(N) Yang-Mills theory in 4 dimensions is dual to the type IIB string theory compactified on AdS_5 x S^5. Mos…
Noncommutative Open String: Neutral and Charged
Chong-Sun Chu
We review the quantization of open string in NS-NS background and demonstrate that its endpoint becomes noncommutative. The same approach allows us to determine the noncommutativit…
