Integral Coefficients for One-Loop Amplitudes
Ruth Britto, Bo Feng
We present a set of algebraic functions for evaluating the coefficients of the scalar integral basis of a general one-loop amplitude. The functions are derived from unitarity cuts,…
Polymer Translocation out of Planar Confinements
Debabrata Panja, Gerard T. Barkema, Robin C. Ball
Polymer translocation in three dimensions out of planar confinements is studied in this paper. Three membranes are located at , and . These membranes are impenet…
Pore-blockade Times for Field-Driven Polymer Translocation
Henk Vocks, Debabrata Panja, Gerard T. Barkema +1
We study pore blockade times for a translocating polymer of length , driven by a field across the pore in three dimensions. The polymer performs Rouse dynamics, i.e., we con…
Are There Four-Dimensional Small Black Rings?
Norihiro Iizuka, Masaki Shigemori
In d>4 dimensions, one can argue for the existence of small black rings using a scaling argument. We apply the same scaling argument to the d=4 case and demonstrate that it fails t…
G2 Hitchin functionals at one loop
Jan de Boer, Paul de Medeiros, Sheer El-Showk +1
We consider the quantization of the effective target space description of topological M-theory in terms of the Hitchin functional whose critical points describe seven-manifolds wit…
Classical approximation to quantum cosmological correlations
Meindert van der Meulen, Jan Smit
We investigate up to which order quantum effects can be neglected in calculating cosmological correlation functions after horizon exit. As a toy model, we study theory on a d…
