- Mean distribution approach to spin and gauge theoriesItem type: Journal Article
Nuclear Physics BÅkerlund, Oscar; de Forcrand, Philippe (2016)We formulate self-consistency equations for the distribution of links in spin models and of plaquettes in gauge theories. This improves upon known mean-field, mean-link, and mean-plaquette approximations in such that we self-consistently determine all moments of the considered variable instead of just the first. We give examples in both Abelian and non-Abelian cases. - Matrix product approximations to conformal field theoriesItem type: Journal Article
Nuclear Physics BKönig, Robert; Scholz, Volkher B. (2017)We establish rigorous error bounds for approximating correlation functions of conformal field theories (CFTs) by certain finite-dimensional tensor networks. For chiral CFTs, the approximation takes the form of a matrix product state. For full CFTs consisting of a chiral and an anti-chiral part, the approximation is given by a finitely correlated state. We show that the bond dimension scales polynomially in the inverse of the approximation error and sub-exponentially in inverse of the minimal distance between insertion points. We illustrate our findings using Wess–Zumino–Witten models, and show that there is a one-to-one correspondence between group-covariant MPS and our approximation. - Bose–Einstein correlations in charged current muon–neutrino interactions in the NOMAD experiment at CERNItem type: Journal Article

Nuclear Physics BVettorazzo, Michele; de Forcrand, Philippe (2004) - BTZ and thermal AdS torus partition functionsItem type: Journal Article
Nuclear Physics BKaundinya, Roshan; Nippanikar, Omkar Vinayak; Singh, Akash; et al. (2024)We rewrite the worldsheet torus partition function of the Thermal AdS CFT by isolating the boundary parameters. Using this, we show that the spectrum of the Euclidean BTZ black hole and Lorentzian AdS3 can be extracted – the latter as a zero temperature limit. A similar procedure recovers the Lorentzian BTZ spectrum proposed in an earlier work. We then use our expression to construct a boundary modular invariant expression as a Poincaré series.
