We propose to determine the coefficients in the Fermilab heavy quark action by matching the finite-volume, off-shell, gauge-fixed propagator and vertex functions with those determined in the exact, relativistic theory. The matching relativistic amplitudes may be determined either from short-distance perturbation theory or from finite-volume step-scaling recursion. Tree-level matching and non-pe...

The tight-binding type theory for cleaved alloys by Bennemann et al. has been extended to include the effects of the random transfer integrals (off-diagonal disorder). The chemisorption and segregation behavior of cleaved alloys is investigated in detail including both the diagonal and off-diagonal disorder. I t is demonstrated that the effects of the off-diagonal disorder are very important fo...

Stellar amplitude interferometry is limited by the need to have optical distances fixed and known to a fraction of the wavelength. We suggest reviving intensity interferometry, which requires hardware which is many orders of magnitude less accurate, at the cost of more limited sensitivity. We present an algorithm to use the very high redundancy of a uniform linear array to increase the sensitiv...

In part I of this work, we presented a theory for adhesionless contact of a pressurized neo-Hookean plane-strain membrane to a rigid substrate. Here, we extend our theory to include adhesion using a fracture mechanics approach. This theory is used to study contact hysteresis commonly observed in experiments. Detailed analysis is carried out to highlight the differences between frictionless and ...

Recently, background independent open-string field theory has been formally defined in the space of all two-dimensional world-sheet theories. In this paper, to make the construction more concrete, I compute the action for an off-shell tachyon field of a certain simple type. From the computation it emerges that, although the string field action does not coincide with the world-sheet (matter) par...

We address the dynamics of a drop with viscosity lh breaking up inside another fluid of viscosity h. We track the time evolution of the drop near snap-off in the experiments and then compare with a scaling theory developed for l 1. The theory is in excellent agreement with both the experiments and the previous simulations of Lister and Stone. Finally, we also investigate the l dependence of the...

We study chiral vertex operators in the sine-Gordon [SG] theory, viewed as an off-conformal system. We find that these operators, which would have been primary fields in the conformal limit, have interesting and, in some ways, unexpected properties in the SG model. Some of them continue to have scaleinvariant dynamics even in the presence of the non-conformal cosine interaction. For instance, i...

The motivating thought behind this volume is that " if one wants to " make up the rules " of the game of life, one has to start from a realistic view of its players " (Engelen 2008, 2). This may seem self evident but it is an idea that rarely achieves the prominence which it deserves—not least in methodological debates. For example, much ink has been spilled around Friedman's famous 1953 essay ...
