Abstract We study ZZ instanton corrections in the (2, 4k) N $$ \mathcal{N} $$ = 1 minimal superstring theory with the type 0B GSO projection, which becomes the type 0B N $$ \mathcal{N} $$ = 1 super-JT gravity in the k → ∞ limit. Each member of th

Abstract We study the leading nonperturbative corrections to the strong-coupling (ungapped) phase of the Gross-Witten-Wadia (GWW) integral over unitary matrices, to one-loop order. We compute these corrections directly in terms of eigenvalue tunnelin

Abstract We compute the ZZ annulus one-point function of the cosmological constant operator in non-critical string theory, regulating divergences from the boundaries of moduli space using string field theory. We identify a subtle issue in a previous

Abstract We compute the normalization of the general multi-instanton contribution to the partition function of (p′, p) minimal string theory and also to the dual two-matrix integral. We find perfect agreement between the two results.

Abstract We use insights from string field theory to analyze and cure the divergences in the cylinder diagram in minimal string theory with both boundaries lying on a ZZ brane. We focus on theories with worldsheet matter consisting of the (2, p) mini

Idiopathic recurrent pericarditis (IRP) can be the hallmark of an autoinflammatory syndrome with recurrent attacks of chest pain and symptom-free intervals following an acute episode. The recurrence rate may be 35% in the pediatric population, freque

We derive an exact convergent expression for the partition function of the $\mathcal{N}=1$ $(2,4k)$ minimal superstring theory with type 0B GSO projection in the ungapped phase by leveraging the duality between this theory and a double-scaled unitary

Starting with late 2018, a new archaeological research project has been unfolding in the framework funded by the Romanian Governmental Unit for Research and Development (UEFISCDI) dedicated to top fundamental research, as one of the few winners of 20

We study ZZ instanton corrections in the $(2,4k)$ $N=1$ minimal superstring theory with the type 0B GSO projection, which becomes the type 0B $N=1$ super-JT gravity in the $k \to \infty$ limit. Each member of the $(2,4k)$ family of theories has two p
