Antibranes and crossing symmetry
Vipul Periwal
Crossing symmetry appears in Dbrane-anti-Dbrane dynamics in the form of an analytic continuation from U(N) for N brane amplitudes to U(N-p,p) for the interactions of N-p branes wit…
Matrices on a point as the theory of everything
Vipul Periwal
It is shown that the world-line can be eliminated in the matrix quantum mechanics conjectured by Banks, Fischler, Shenker and Susskind to describe the light-cone physics of M theor…
Flow of low energy couplings in the Wilson renormalization group
Robert C. Myers, Vipul Periwal
A new form of the Wilson renormalization group equation is derived, in which the flow equations are, up to linear terms, proportional to a gradient flow. A set of coördinates is fo…
Quantum logic as a sum over classical logic gates
Bruno Nachtergaele, Vipul Periwal
It is shown that certain natural quantum logic gates, {\it i.e.} unitary time evolution matrices for spin-\frac{1}{2} quantum spins, can be represented as sums, with appropriate ph…
D-brane recoil
Vipul Periwal, Øyvind Tafjord
It is shown that there are logarithmic operators in D-brane backgrounds that lead to infrared divergences in open string loop amplitudes. These divergences can be cancelled by chan…
Critical theory of turbulence in incompressible fluids
Vipul Periwal
The Navier-Stokes equation describes the deterministic evolution of incompressible fluids. The effects of random initial conditions on solutions of this equation are studied. It is…
