Revealing topology in metals using experimental protocols inspired by K-theory
Nature Communications, 2023 Topological metals are conducting materials with gapless band structures and nontrivial edge-localized resonances. Their discovery has proven elusive because traditional topological classification methods require band gaps to define topological ...

Quarter-BPS states, multi-symmetric functions and set partitions
Journal of High Energy Physics, 2021 We give a construction of general holomorphic quarter BPS operators in N $$ \mathcal{N} $$ = 4 SYM at weak coupling with U(N) gauge group at finite N. The construction employs the Möbius inversion formula for set partitions, applied to multi-symmetric ...

Relative anomaly in (1+1)d rational conformal field theory
Physical Review Research, 2020 We study 't Hooft anomalies of symmetry-enriched rational conformal field theories (RCFT) in (1+1)d. Such anomalies determine whether a theory can be realized in a truly (1+1)d system with on-site symmetry, or on the edge of a (2+1)d symmetry-protected ...

Higher topological Hochschild homology of periodic complex K-theory [PDF]
, 2020 We describe the topological Hochschild homology of the periodic complex $K$-theory spectrum, $THH(KU)$, as a commutative $KU$-algebra: it is equivalent to $KU[K(\mathbb{Z},3)]$ and to $F(\Sigma KU_{\mathbb{Q}})$, where $F$ is the free commutative $KU ...

Homotopy Batalin-Vilkovisky algebras [PDF]
, 2010 This paper provides an explicit cofibrant resolution of the operad encoding Batalin-Vilkovisky algebras. Thus it defines the notion of homotopy Batalin-Vilkovisky algebras with the required homotopy properties.

Structure of Topological Lattice Field Theories in Three Dimensions [PDF]
, 1993 We construct and classify topological lattice field theories in three dimensions. After defining a general class of local lattice field theories, we impose invariance under arbitrary topology-preserving deformations of the underlying lattice, which are ...

Algebraic Quantum Theory on Manifolds: A Haag-Kastler Setting for Quantum Geometry [PDF]
, 2000 Motivated by the invariance of current representations of quantum gravity under diffeomorphisms much more general than isometries, the Haag-Kastler setting is extended to manifolds without metric background structure.

Algebras with actions and automata
International Journal of Mathematics and Mathematical Sciences, 1982 In the present paper we want to give a common structure theory of left action, group operations, R-modules and automata of different types defined over various kinds of carrier objects: sets, graphs, presheaves, sheaves, topological spaces (in particular:

A noncommutative model for higher twisted K-Theory [PDF]
, 2015 We develop a operator algebraic model for twisted $K$-theory, which includes the most general twistings as a generalized cohomology theory (i.e. all those classified by the unit spectrum $bgl_1(KU)$).
