5d SCFT fixtures
Michele Del Zotto, Andrea Sangiovanni
In the context of the atomic classification of 5d SCFTs building blocks with non-simply laced global symmetries are lacking. In this work we fill this gap by introducing a new clas…
5d Higgs Branches: Stratifications from Geometry
Mario De Marco, Michele Del Zotto, Julius Grimminger +1
Higgs Branches of 5d SCFTs are hyperkähler cones, symplectic varieties with interesting nested singularities governing the structure of possible Higgs branch RG flows. The main pur…
5d Trinions and Tetraons
Mario De Marco, Michele Del Zotto, Michele Graffeo +1
Recently, an atomic classification scheme of 5d SCFTs has been proposed, relying on the identification of indecomposable building blocks that can be fused together to produce large…
From Multipartite Entanglement to TQFT
Michele Del Zotto, Abhijit Gadde, Pavel Putrov
At long distances, a gapped phase of matter is described by a topological quantum field theory (TQFT). We conjecture a tight and concrete relationship between the genuine -p…
SymTFT for Continuous Symmetries: Non-linear Realizations and Spontaneous Breaking
Federico Bonetti, Michele Del Zotto, Ruben Minasian
It is well known that continuous symmetries of quantum fields can be realized non-linearly, e.g. in the context of sigma models, and can also be spontaneously broken on non-compact…
Remarks on Geometric Engineering, Symmetry TFTs and Anomalies
Michele Del Zotto, Shani Nadir Meynet, Robert Moscrop
Geometric engineering is a collection of tools developed to establish dictionaries between local singularities in string theory and (supersymmetric) quantum fields. Extended operat…
SymTFTs for Continuous non-Abelian Symmetries
Federico Bonetti, Michele Del Zotto, Ruben Minasian
Topological defects and operators give a far-reaching generalization of symmetries of quantum fields. An auxiliary topological field theory in one dimension higher than the QFT of…
Topological defects
Nils Carqueville, Michele Del Zotto, Ingo Runkel
This is a survey article for the Encyclopedia of Mathematical Physics, 2nd Edition. Topological defects are described in the context of the 2-dimensional Ising model on the lattice…
The ALE Partition Functions of M-String Orbifolds
Michele Del Zotto, Guglielmo Lockhart
The ALE partition functions of a 6d (1,0) SCFT are interesting observables which are able to detect the global structure of the SCFT. They are defined to be the equivariant partiti…
5d Conformal Matter
Mario De Marco, Michele Del Zotto, Michele Graffeo +1
Six-dimensional superconformal field theories (SCFTs) have an atomic classification in terms of elementary building blocks, conformal systems that generalize matter and can be fuse…
The ALE Partition Functions of M-Strings
Michele Del Zotto, Guglielmo Lockhart
We compute the equivariant partition function of the six-dimensional M-string SCFTs on a background with the topology of a product of a two-dimensional torus and an ALE singularity…
The Higgs branch of Heterotic ALE instantons
Michele Del Zotto, Marco Fazzi, Suvendu Giri
We begin a study of the Higgs branch of six-dimensional little string theories governing the worldvolumes of heterotic ALE instantons. We give a description of this space b…
A new vista on the Heterotic Moduli Space from Six and Three Dimensions
Michele Del Zotto, Marco Fazzi, Suvendu Giri
We settle a long-standing question about the hypermultiplet moduli spaces of the heterotic strings on ALE singularities. These heterotic backgrounds are specified by the singularit…
Four-manifolds and Symmetry Categories of 2d CFTs
Vladimir Bashmakov, Michele Del Zotto, Azeem Hasan
In this paper we study the geometric origin of non-invertible symmetries of 2d theories arising from the reduction of 6d theories on four-manifolds. This generalizes and ex…
Junctions, Edge Modes, and -Holonomy Orbifolds
Bobby Samir Acharya, Michele Del Zotto, Jonathan J. Heckman +2
One of the general strategies for realizing a wide class of interacting QFTs is via junctions and intersections of higher-dimensional bulk theories. In the context of string/M-theo…

Michele Del Zotto, Muyang Liu, Paul-Konstantin Oehlmann
We review here some aspects of our recent works about the geometric engineering of heterotic little string theories using F-theory. Building on the seminal work by Aspinwall and Mo…

In this paper we begin revisiting the little string theories (LSTs) which govern the dynamics of the instantonic heterotic five-branes probing ALE singularities, b…
On the 6d Origin of Non-invertible Symmetries in 4d
Vladimir Bashmakov, Michele Del Zotto, Azeem Hasan
It is well-known that six-dimensional superconformal field theories can be exploited to unravel interesting features of lower-dimensional theories obtained via compactifications. I…
Global Structures from the Infrared
Michele Del Zotto, Iñaki García Etxebarria
Quantum field theories with identical local dynamics can admit different choices of global structure, leading to different partition functions and spectra of extended operators. Su…

Michele Del Zotto, Iñaki García Etxebarria, Sakura Schafer-Nameki
Quantum Field Theories engineered in M-theory can have 2-group symmetries, mixing 0-form and 1-form symmetry backgrounds in non-trivial ways. In this paper we develop methods for d…
