Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Tenyo Kawamura, Chris Done, Magnus Axelsson, Tadayuki Takahashi, | Summary: Black hole X-ray binaries in the low/hard states display significant broad-band (stochastic) variability on short time-scales (0.01-100 seconds), with a complex pattern of lags in correlated variability seen in different energy bands. This behaviour is generally interpreted […]

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Brian Henning, Hitoshi Murayama, Francesco Riva, Jedidiah O. Thompson, Matthew T. Walters | Summary: We present a nonperturbative recipe for directly computing the $S$-matrix in strongly-coupled QFTs. The method makes use of spectral data obtained in a Hamiltonian framework and can be applied to a wide range […]

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Benjamin Assel, Yuji Tachikawa, Alessandro Tomasiello, , | Summary: We introduce a class of 3d theories consisting of strongly-coupled ${mathcal N}=4$ systems coupled to ${mathcal N}=3$ Chern-Simons gauge multiplets, which exhibit ${mathcal N}=4$ enhancements when a peculiar condition on the Chern-Simons levels is met. An example is […]
