Non-Relativistic Closed String Theory
Jaume Gomis, Hirosi Ooguri
We construct a Galilean invariant non-gravitational closed string theory whose excitations satisfy a non-relativistic dispersion relation. This theory can be obtained by taking a c…
On Theories With Light-Like Noncommutativity
Ofer Aharony, Jaume Gomis, Thomas Mehen
We show that field theories with light-like noncommutativity, that is with , are unitary quantum theories, and that they can be obtained as decoupled field theory l…
Quantum Field Theories With Compact Noncommutative Extra Dimensions
Jaume Gomis, Thomas Mehen, Mark B. Wise
We study field theories on spaces with additional compact noncommutative dimensions. As an example, we study ϕ^3 on R^{1,3}\times T^{2}_θusing perturbation theory. The infrared div…
Space-Time Noncommutative Field Theories And Unitarity
Jaume Gomis, Thomas Mehen
We study the perturbative unitarity of noncommutative scalar field theories. Field theories with space-time noncommutativity do not have a unitary S-matrix. Field theories with onl…
Noncommutative Gauge Dynamics From The String Worldsheet
Jaume Gomis, Matthew Kleban, Thomas Mehen +2
We show how string theory can be used to reproduce the one-loop two-point photon amplitude in noncommutative U(1) gauge theory. Using a simple realization of the gauge theory in bo…
D-branes on Orbifolds with Discrete Torsion And Topological Obstruction
Jaume Gomis
We find the orbifold analog of the topological relation recently found by Freed and Witten which restricts the allowed D-brane configurations of Type II vacua with a topologically…
