Abstract Recently, a superdiffusion exhibiting the Kardar-Parisi-Zhang (KPZ) scaling in late-time correlators and autocorrelators of certain interacting many-body systems, such as Heisenberg spin chains, has been reported. Inspired by these results,

Abstract We conjecture a formula for the spectral form factor of a double-scaled matrix integral in the limit of large time, large density of states, and fixed temperature. The formula has a genus expansion with a nonzero radius of convergence. To un

Abstract We study the ℤ2 and U(1) Abelian lattice gauge theories using a bootstrap method, in which the loop equations and positivity conditions are employed for Wilson loops with lengths L ⩽ L max to derive two-sided bounds on the Wilson loop av

Abstract We consider the two-dimensional Schwinger model of a massless charged fermion coupled to an Abelian gauge field on a fixed de Sitter background. The theory admits an exact solution, first examined by Jayewardena, and can be analyzed efficien

Abstract In this work we conjecture the Coulomb branch partition function, including flux and instanton contributions, for the N $$ \mathcal{N} $$ = 2 vector multiplet on weighted projective space CP N 2 $$ {\mathbbm{CP}}_N^2 $$ for equivariant Donal

Abstract This paper investigates the impact of small instanton effects on the axion mass in composite axion models. In particular, we focus on the Composite Accidental Axion (CAA) models, which are designed to address the axion quality problem, and w

Abstract We revisit the hadronization and decay of excited heavy mesons and heavy baryons in Herwig 7 general-purpose event-generator, following four distinct steps: (i) Passing through the polarisation of heavy hadrons at the end of parton shower th

Abstract Recent measurements at the LHC have revealed heavy-flavour baryon fractions much larger than those observed at LEP, with e.g., Λ c + / D 0 $$ {\Lambda}_c^{+}/{\textrm{D}}^0 $$ and Λ b 0 / B 0 $$ {\Lambda}_b^0/{\textrm{B}}^0 $$ reaching ∼

Abstract We study non-invertible topological symmetry operators in massive quantum field theories in (1+1) dimensions. In phases where this symmetry is spontaneously broken we show that the particle spectrum often has degeneracies dictated by the non
