Practical animation of liquids
 Graphical Models and Image Processing
, 1996
"... We present a comprehensive methodology for realistically animating liquid phenomena. Our approach unifies existing computer graphics techniques for simulating fluids and extends them by incorporating more complex behavior. It is based on the NavierStokes equations which couple momentum and mass con ..."

Stokes equations to include forcing functions. Free surfaces in our system are represented as either a collection of massless particles in 2D, or a height field which is suitable for many of the water rendering algorithms presented by researchers in recent years.
Massless Black Holes and Conifolds in String Theory
"... Lowenergy effective field theories arising from CalabiYau string compactifications are generically inconsistent or illdefined at the classical level because of conifold singularities in the moduli space. It is shown, given a plausible assumption on the degeneracies of black hole states, that for ..."

, that for type II theories this inconsistency can be cured by nonperturbative quantum effects: the singularities are resolved by the appearance of massless RamondRamond black holes. The Wilsonian effective action including these light black holes is smooth near the conifold, and the singularity is reproduced
Anti de Sitter space and holography
, 1998
"... Recently, it has been proposed by Maldacena that large N limits of certain conformal field theories in d dimensions can be described in terms of supergravity (and string theory) on the product of d+1dimensional AdS space with a compact manifold. Here we elaborate on this idea and propose a precise ..."

correspondence between conformal field theory observables and those of supergravity: correlation functions in conformal field theory are given by the dependence of the supergravity action on the asymptotic behavior at infinity. In particular, dimensions of operators in conformal field theory are given by masses
Noncommutative Perturbative Dynamics
 hepth/9912072; M. Van Raamsdonk and N. Seiberg, “Comments On Noncommutative Perturbative Dynamics,” JHEP 0003 (2000) 035, hepth/0002186
"... We study the perturbative dynamics of noncommutative field theories on Rd, and find an intriguing mixing of the UV and the IR. High energies of virtual particles in loops produce nonanalyticity at low momentum. Consequently, the low energy effective action is singular at zero momentum even when the ..."

Extended conformal algebra and noncommutative geometry in particle theory
"... We show how an off shell invariance of the massless particle action allows the construction of an extension of the conformal spacetime algebra and induces a noncommutative spacetime geometry in bosonic and supersymmetric particle theories. 1 ..."

Massless interacting particles
, 2008
"... We show that classical electrodynamics of massless charged particles and the Yang–Mills theory of massless quarks do not experience rearranging their initial degrees of freedom into dressed particles and radiation. Massless particles do not radiate. We consider a version of the direct interparticle ..."

Massive Particles from Massless Spinors

"... ”Hark ye...the little lower layer. All visible objects, man, are but as pasteboard masks... If man would strike, strike through the mask! ” (Herman Melville; Moby Dick). Abstract: Spinors are lightlike. How do they combine to make massive particles? We visit the zoo of Lagrangian singularities, or c ..."

by multiplicity s reflections: ”mass scatterings ” off the vacuum spinors, that keep chiral pairs of matter envelopes confined to a timelike world tube, endowing a bispinor particle with mass. Using the volume in spin space as the action, the particle masses emerge in terms of the multiplicities, s: the number

Radiation reaction for a massless charged particle

It is shown that unlike the massive case not all the divergences resulting from the selfaction of the particle are Lagrangian, i.e. ca ..."
