We show that the low-energy effective actions of two ten-dimensional supersymmetric heterotic strings are different by a $\mathbb{Z}_3$-valued discrete topological term even after we turn off the $E_8×E_8$ and $Spin(32)/\mathbb{Z}_2$ gauge fields. T

Abstract We introduce a class of 3d theories consisting of strongly-coupled N $$ \mathcal{N} $$ = 4 systems coupled to N $$ \mathcal{N} $$ = 3 Chern-Simons gauge multiplets, which exhibit N $$ \mathcal{N} $$ = 4 enhancements when a peculiar condition

Abstract It is known that the asymptotic density of states of a 2d CFT in an irreducible representation ρ of a finite symmetry group G is proportional to (dim ρ)2. We show how this statement can be generalized when the symmetry can be non-invertibl

Abstract We argue that having an odd number of Majorana fermion zero modes on a dynamical point-like soliton signifies an inconsistency in a theory with 3+1 and higher dimensions. We check this statement in a couple of examples in field theory and in

Abstract We study higher symmetries and anomalies of 4d so $$ \mathfrak{so} $$ (2n c ) gauge theory with 2n f flavors. We find that they depend on the parity of n c and n f , the global form of the gauge group, and the discrete theta angle. The contr

Abstract We carry out a systematic study of 4d N $$ \mathcal{N} $$ = 2 preserving S-folds of F-theory 7-branes and the worldvolume theories on D3-branes probing them. They consist of two infinite series of theories, which we denote following [1, 2] b

Abstract We derive the general anomaly polynomial for a class of two-dimensional CFTs arising as twisted compactifications of a higher-dimensional theory on compact manifolds ℳ d , including the contribution of the isometries of ℳ d . We then use

Abstract We revisit the N $$ \mathcal{N} $$ = 6 superconformal Chern-Simons-matter theories and their supergravity duals in the context of generalized symmetries. This allows us to finally clarify how the SU(N ) × SU(N ) and (SU(N ) × SU(N ))/ℤ N

Abstract We point out that the moduli spaces of all known 3d N $$ \mathcal{N} $$ = 8 and N $$ \mathcal{N} $$ = 6 SCFTs, after suitable gaugings of finite symmetry groups, have the form ℂ 4r /Γ where Γ is a real or complex reflection group dependi

Abstract We discuss a strategy to construct gapped boundaries for a large class of symmetry-protected topological phases (SPT phases) beyond group cohomology. This is done by a generalization of the symmetry extension method previously used for cohom
