Learning about Quantum Gravity with a Couple of Nodes [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2012 Loop Quantum Gravity provides a natural truncation of the infinite degrees of freedom of gravity, obtained by studying the theory on a given finite graph. We review this procedure and we present the construction of the canonical theory on a simple graph,

Heterotic-string amplitudes at one loop: modular graph forms and relations to open strings [PDF]
Journal of High Energy Physics, 2019 We investigate one-loop four-point scattering of non-abelian gauge bosons in heterotic string theory and identify new connections with the corresponding open-string amplitude.

Supergravity limit of genus two modular graph functions in the worldline formalism
Physics Letters B, 2018 We consider the contributions up to the D10R4 terms in the low momentum expansion of the two loop four graviton amplitude in maximal supergravity that arise in the field theory limit of genus two modular graph functions that result from the low momentum ...

Learning from Heterophilic Graphs: A Spectral Theory Perspective on the Impact of Self-Loops and Parallel Edges [PDF]
Graph heterophily poses a formidable challenge to the performance of Message-passing Graph Neural Networks (MP-GNNs). The familiar low-pass filters like Graph Convolutional Networks (GCNs) face performance degradation, which can be attributed to the blending of the messages from dissimilar neighboring nodes.

A supersymmetric exotic field theory in (1+1) dimensions: one loop soliton quantum mass corrections
Journal of High Energy Physics, 2018 We consider one loop quantum corrections to soliton mass for the N = 1 $$ \mathcal{N}=1 $$ supersymmetric extension of the (1+1)-dimensional scalar field theory with the potential U (ϕ) = ϕ 2 cos2 (ln ϕ 2).

Nuclear Physics B, 2015 We study the expectation value of a nonplanar Wilson graph operator in SL(2,C) Chern–Simons theory on S3. In particular we analyze its asymptotic behavior in the double-scaling limit in which both the representation labels and the Chern–Simons coupling ...

One loop tadpole in heterotic string field theory
Journal of High Energy Physics, 2017 We compute the off-shell 1-loop tadpole amplitude in heterotic string field theory. With a special choice of cubic vertex, we show that this amplitude can be computed exactly.
