The dilatation operator for defect conformal N=4 SYM
Asger C. Ipsen, Kasper E. Vardinghus
We compute the dilatation operator for local "open string" operators situated at the interface of a certain supersymmetric defect version of super-Yang-Mills theory…
The One-Loop Spectral Problem of Strongly Twisted =4 Super Yang-Mills Theory
Asger C. Ipsen, Matthias Staudacher, Leonard Zippelius
We investigate the one-loop spectral problem of -twisted, planar =4 Super Yang-Mills theory in the double-scaling limit of infinite, imaginary twist angle and vanis…
Disturbance in weak measurements and the difference between quantum and classical weak values
Asger C. Ipsen
The role of measurement induced disturbance in weak measurements is of central importance for the interpretation of the weak value. Uncontrolled disturbance can interfere with the…
A note on the Lee-Yang singularity coupled to 2d quantum gravity
J. Ambjorn, A. Goerlich, A. Ipsen +1
We show how to obtain the critical exponent of magnetization in the Lee-Yang edge singularity model coupled to two-dimensional quantum gravity.
New Bessel Identities from Laguerre Polynomials
Asger C. Ipsen
For large order, Laguerre polynomials can be approximated by Bessel functions near the origin. This can be used to turn many Laguerre identities into corresponding identities for B…
