Ground ring for the 2D NSR string
P. Bouwknegt, J. McCarthy, K. Pilch
We discuss the BSRT quantization of 2D supergravity coupled to superconformal matter with in the conformal gauge. The physical states are computed as BRST co…
Semi-infinite cohomology of W-algebras
P. Bouwknegt, J. McCarthy, K. Pilch
We generalize some of the standard homological techniques to $\cW$-algebras, and compute the semi-infinite cohomology of the $\cW_3$ algebra on a variety of modules. These computat…
Evidence for Efimov quantum states in an ultracold gas of cesium atoms
T. Kraemer, M. Mark, P. Waldburger +8
Systems of three interacting particles are notorious for their complex physical behavior. A landmark theoretical result in few-body quantum physics is Efimov's prediction of a univ…
Determination of atomic scattering lengths from measurements of molecular binding energies near Feshbach resonances
A. D. Lange, K. Pilch, A. Prantner +5
We present an analytic model to calculate the atomic scattering length near a Feshbach resonance from data on the molecular binding energy. Our approach considers finite-range squa…
BRST Analysis of Physical States for 2D (Super) Gravity Coupled to (Super) Conformal Matter
P. Bouwknegt, J. McCarthy, K. Pilch
We summarize some recent results on the BRST analysis of physical states of 2D gravity coupled to c<=1 conformal matter and the supersymmetric generalization.
The deformed Virasoro algebra at roots of unity
P. Bouwknegt, K. Pilch
We discuss some aspects of the representation theory of the deformed Virasoro algebra $\virpq$. In particular, we give a proof of the formula for the Kac determinant and then deter…
