Small black hole explosions by Roberta Angius, Jesús Huertas, Angel M. Uranga

“…Along the way we show that many regular black hole supergravity solutions in the literature in the latter context are incomplete, due to Freed-Witten anomalies (or duals thereof), and require the emission of strings by the black hole. …”

Topological nonlinear σ -model, higher gauge theory, and a systematic construction of 3 + 1 D topological orders for boson systems by Zhu, Chenchang, Lan, Tian, Wen, Xiao-Gang

“…X 8, 021074 (2018)2160-330810.1103/PhysRevX.8.021074], it is shown that, if K is a space with only nontrivial first homotopy group G, which is finite, then these topological nonlinear σ-models can already realize all 3+1D bosonic topological orders without emergent fermions, which are described by Dijkgraaf-Witten theory with gauge group π1(K)=G. Under the similar conjecture, we show that the 3+1D bosonic topological orders with emergent fermions can be realized by topological nonlinear σ-models with π1(K)= finite groups, π2(K)=Z2, and πn>2(K)=0. …”

Two-dimensional symmetry-protected topological orders and their protected gapless edge excitations by Chen, Xie, Liu, Zheng-Xin, Wen, Xiao-Gang

“…The order is nontrivial because we can prove that the one-dimensional (1D) system on the boundary must be gapless if the symmetry is not broken, which generalizes the gaplessness of Wess-Zumino-Witten model for Lie symmetry groups to any discrete symmetry groups. …”

Investigations in Calabi-Yau modularity and mirror symmetry by McGovern, J

“…</p> <p>We provide several instances of summation identities that express a ratio of critical L-values as an infinite sum, whose terms contain the Gromov-Witten invariants of a Calabi-Yau manifold Y . In one example there is no manifold Y, only an operator, but a set of invariants can nonetheless be computed for this and a summation identity is found. …”

Modular Calabi-Yau manifolds, attractor points, and flux vacua by Kuusela, P

“…In some important special cases we find closed-form series solutions, which can be used to compute the entropy of associated black holes in terms of Gromov-Witten invariants of the compactification manifold. …”
