Gauge theories as matrix models [PDF]
Theoretical and Mathematical Physics, 2011 The relation between the Seiberg-Witten prepotentials, Nekrasov functions and matrix models is discussed. We derive quasiclassically the matrix models of Eguchi-Yang type, describing the instantonic contribution to the deformed partition functions of supersymmetric gauge theories.

Towards a double scaling limit for tensor models: probing sub-dominant orders
New Journal of Physics, 2014 The definition of a double scaling limit represents an important goal in the development of tensor models. We take the first steps towards this goal by extracting and analysing the next-to-leading order contributions, in the 1/N expansion, for the ...

Quadrality for supersymmetric matrix models
Journal of High Energy Physics, 2017 We introduce a new duality for N $$ \mathcal{N} $$ = 1 supersymmetric gauged matrix models. This 0d duality is an order 4 symmetry, namely an equivalence between four different theories, hence we call it Quadrality.

Interpolating matrix models for WLZZ series
European Physical Journal C: Particles and Fields, 2023 We suggest a two-matrix model depending on three (infinite) sets of parameters which interpolates between all the models proposed in Wang et al. (Eur Phys J C 82:902, arXiv:2206.13038 , 2022) and defined there through W-representations.

Pseudo-hermitian random matrix models: General formalism
Nuclear Physics B, 2022 Pseudo-hermitian matrices are matrices hermitian with respect to an indefinite metric. They can be thought of as the truncation of pseudo-hermitian operators, defined over some Krein space, together with the associated metric, to a finite dimensional ...

Integrable matrix models in discrete space-time
SciPost Physics, 2020 We introduce a class of integrable dynamical systems of interacting classical matrix-valued fields propagating on a discrete space-time lattice, realized as many-body circuits built from elementary symplectic two-body maps.

Field theory as a matrix model [PDF]
Nuclear Physics B, 2000 A new formulation of four dimensional quantum field theories, such as scalar field theory, is proposed as a large N limit of a special NxN matrix model. Our reduction scheme works beyond planar approximation and applies for QFT with finite number of fields. It uses quenched coordinates instead of quenched momenta of the old Eguchi-Kawai reduction known
