Abstract: We study the $O(N)^3$ supersymmetric quantum field theory of a scalar superfield $\Phi_{abc}$ with a tetrahedral interaction. In the large $N$ limit the theory is dominated by the melonic diagrams. We solve the corresponding Dyson-Schwinger… read more here.

Abstract: The SYK model has a wormhole-like solution after averaging over the fermionic couplings in the nearly AdS2 space. Even when the couplings are fixed the contribution of these wormholes continues to exist and new saddle… read more here.

DOI: 10.1103/physreve.100.012706
Abstract: Most, but not all, liquid crystals tend to align when subject to shear flow, while most nematic polymeric liquid crystals undergo a tumbling instability, where the director rotates with the flow. The reasons of this… read more here.
