The charge radius of a Dpbrane
Michael Gutperle, Vipul Periwal
Sen has shown that tachyon condensation in Dbrane-anti-Dbrane configurations can lead to remarkable connections between string theories. A consequence of his results is that there…
Dbrane boundstate wavefunctions
Vipul Periwal
A simple WKB approximation gives explicit information about D0brane boundstate wavefunctions, suggesting that at large each individual D0brane has a wavefunction $\exp(- c r^{9…
Monopole condensates in SU(N) Yang-Mills Theory
Vipul Periwal
Faddeev and Niemi have proposed a reformulation of SU(2) Yang-Mills theory in terms of new variables, appropriate for describing the theory in its infrared limit based on the intui…
Functional statistical inference of parton distributions
Vipul Periwal
Bialek, Callan and Strong have recently given a solution of the problem of determining a continuous probability distribution from a finite set of experimental measurements by formu…
The topology of events
Vipul Periwal
A matrix model is constructed to compute characteristic numbers of the space of subsets of with elements. This matrix model is found to be a constrained null dimensional…
Matrix string interactions
Vipul Periwal, Oyvind Tafjord
String configurations have been identified in compactified Matrix theory at vanishing string coupling. We show how the interactions of these strings are determined by the Yang-Mill…
A finite cutoff on the string worldsheet?
Vipul Periwal, Øyvind Tafjord
D-brane backgrounds are specified in closed string theories by holes with appropriate mixed Dirichlet and Neumann boundary conditions on the string worldsheet. As presently stated,…
Minimal subtraction and the Callan-Symanzik equation
J. Naud, I. Nemenman, M. Van Raamsdonk +1
The usual proof of renormalizability using the Callan-Symanzik equation makes explicit use of normalization conditions. It is shown that demanding that the renormalization group fu…
Consistency of Wilsonian effective actions
Vipul Periwal
Wilsonian effective actions are interpreted as free energies in ensembles with prescribed field expectation values and prescribed connected two-point functions. Since such free ene…
Accelerating D-branes
V. Periwal, R. von Unge
Higher derivative terms are computed in the one-loop effective action governing the interactions of D3-branes, in two ways: (1) in a formalism with N=2 supersymmetry preserved off-…
