A great part of the problem of understanding the structure of the space of quantum field theories (QFT) is arguably reduced to the one of classifying possible critical points. In this picture, the theories with mass scales are obtained by perturbing critical points and following the renormalization group (RG) trajectories. However, interestingly, in the flow not all critical points can be joined w

In this talk we will give an overview of recent results obtained from the bootstrap approach to CFTs. We will discuss both analytical and numerical results, including for supersymmetric theories. We identify several promising directions for further research

I will discuss how gravity scattering amplitudes of many different gravitational theories can be obtained from various gauge theories through a doublecopy procedure. The basic idea goes back to the old relation between open and closed strings, but I will argue that gravity being the double copy of two gauge theories is a more general notion. I will present new striking examples of gravity theorie

We consider weaklycoupled theories of massive higherspin particles. This class of models includes, for instance, treelevel String Theory and LargeN YangMills theory. The Smatrix in such theories is a meromorphic function obeying unitarity and crossing symmetry. We discuss the unphysical highenergy fixed imaginary angle scattering regime. We expect the amplitude to be universal and exponenti

The locality of fundamental interactions and the nonlocal
character of quantum correlations are reconciled in the framework of algebraic quantum field theory. The theory is based on the concept of local fields which are mathematically characterized as natural tranformations between suitable functors. The framework covers quantum field theories on generic Lorentzian manifolds including also pertu

Considerable progress has been made in the last few years on various N=2 supersymmetric field theories. The progress includes exact results for expectation values of Wilson loop observables and various other quantities.
In my talk I will review some of these developments, and try to extract some lessons of general interest for a wider audience with interests in quantum field theory.

Perturbation theory for lattice regularization of field theory is known to be a quite hard subject and this holds true in particular for lattice gauge theory. In the 90's the numerical
implementation of stochastic perturbation theory (NSPT) was introduced. NSPT can not only make perturbative computations on the lattice (in some cases much) easier, but also enable the computation of extremely

Besides lattice QCD in particle physics, strongly coupled gauge theories arise, for example, in the condensed matter physics of spin liquids, or in the quantum information theory of Kitaev's toric code, which is a Z(2) lattice gauge theory.
Numerical simulations of gauge theories on classical computers,
in particular, at high fermion density or in outofequilibrium situations, suffer from sever

I will review the gauge theoretical construction of quantum algebras such as qdeformed Walgebras and quantum groups from the geometry of the moduli space of quiver instantons, moduli space of monopoles and moduli space of vacua of N=2 supersymmetric gauge theories.

It has been claimed that the super Hubble modes generated during inflation can make loop corrections diverge. Even if we introduce an infrared (IR) cutoff at a comoving scale as an ad hoc but a practical way for the regularization, we encounter the
secular growth, which may lead to the breakdown of perturbative expansion for a sufficiently long lasting inflation. We show that the IR pathology

The term Tensor Network States (TNS) has become a common one in the context of numerical studies of quantum manybody problems. It refers to a number of families that represent different ansatzes for the efficient description of the state of a quantum manybody system. The first of these families, Matrix Product States (MPS), lies at the basis of Density Matrix Renormalization Group methods, which

The YangMills gradient flow provides new insight into the dynamics of nonAbelian gauge theories and has become a widely used tool in lattice QCD. In this talk, the theoretical foundation of the flow is reviewed and some of its applications are briefly described.

We start by reviewing UV completion of the GrossNeveu model in dimensions between two and four via the GrossNeveuYukawa model,
which is a multiflavor Yukawa theory. We discuss the operator scaling dimensions and the sphere free energy for these Conformal Field Theories.
The case of a single twocomponent Majorana fermion is special in that the theory appears to flow to a CFT with emergent su

The last years have seen remarkable progress in understanding the scattering amplitudes of massless particles in arbitrary dimension. They not only exhibit a simplicity completely obscured by the Feynman Diagram approach, but also a structure strikingly reminiscent of the worldsheet models describing string theory. After reviewing the key developments, I will discuss the worldsheet models, derive
