Dynamical truncation of the string spectrum at finite N
Gilad Lifschytz, Vipul Periwal
We exhibit a nonperturbative background independent dynamical truncation of the string spectrum and a quantization of the string coupling constant directly from the Hamiltonian gov…
A toy model of Polyakov duality
Vipul Periwal
Polyakov has conjectured that Yang-Mills theory should be equivalent to a noncritical string theory. I pointed out, based on the work of Marchesini, Ishibashi, Kawai and collaborat…
Dbrane Phase Transitions and Monodromy in K-theory
Sergei Gukov, Vipul Periwal
Majumder and Sen have given an explicit construction of a first order phase transition in a non-supersymmetric system of Dbranes that occurs when the B field is varied. We show tha…
String field theory Hamiltonians from Yang-Mills theories
Vipul Periwal
Marchesini showed that the Fokker-Planck Hamiltonian for Yang-Mills theories is the loop operator. Jevicki and Rodrigues showed that the Fokker-Planck Hamiltonian of some matrix mo…
Cosmological and astrophysical tests of quantum gravity
Vipul Periwal
Physics in the vicinity of an ultraviolet stable fixed point of a quantum field theory is parametrized by a renormalization group invariant macroscopic length scale, the correlatio…
