Theories of the fundamental interactions

As a driving motivation, our research activities aim to address some of the basic challenging issues presently facing us at the frontiers of the gauge theories of the fundamental quantum interactions and their matter couplings.

On the one hand, for well accepted or even established theories a solid understanding of their non-perturbative dynamics remains largely wanting. Undoubtedly, topological and geometrical properties in field space in relation to large gauge symmetries play crucial roles in this regard, to which perturbative gauge fixing procedures remain totally oblivious. A significant component of our research efforts addresses such issues within lower dimensional gauge theories from complementary non-perturbative points of view, also unraveling dualities between apparently disconnected theories.

Parallel to such studies is the pursuit of novel computational techniques and approaches towards multi-loop scattering amplitudes, on a par with studies of the mathematical structures of Feynman integrals and scattering amplitudes, relying on as many new mathematical frameworks as may be garnered and call on, with the aim to design new mathematical tools for precision computations in QFT, especially for LHC motivated precision processes. In particular, as soon as supersymmetries are involved, especially with N=4 supersymmetry in four dimensional space-time, much progress has been made over recent years and much scope for further understanding remains within reach.

On the other hand, present day gauge theories of the fundamental quantum interactions present their own challenges pointing towards new fundamental conceptual paradigms beyond quantum physics and gravity. Some of the exploratory paths being trodden are deformations of quantum mechanics, non-commutative or fuzzy space-time geometries, and topological theories for pure quantum gravity, being applied in a variety of physical circumstances. Approached from other perspectives, attempts are being pursued as well that aim to relate gauge coupling constant sectors and electroweak flavor coupling constant sectors within new unification schemes for all interactions.

Finally, progress in non-perturbative dynamics of gauge theories has often exploited advances made in condensed matter physics. Collective phenomena in lower dimensional fermionic systems display a variety of behaviors, in particular quantum Hall systems and their recently identified generalizations with a topological understanding having been achieved over the recent years of their distinctive physical properties reminding one of holographic-like properties in theories of gravity, which may well prove relevant to non-perturbative gauge dynamics alike. Thus some part of our research activities addresses such issues as well.

Non-commutative quantum dynamics and supersymmetry

Extensions to the supersymmetric context of the Moyal non-commutative plane are being considered from different perspectives.

Non-perturbative dynamics of QED in low dimensions

By emphasizing the relevance of topology in nonperturbative gauge dynamics in the presence of nontrivial space(time) topology, develop gauge invariant physical tools to approach the nonperturbative dynamics of such systems in approximation schemes. In an initial study, QED in lower dimensions is considered in detail.

Nonperturbative quantisation of gauge theories, noncommutative geometry and unification of the fundamental interactions

Development of nonperturbative quantisation techniques of gauge theories (Yang-Mills, topological, gravity) and their application to particle physics and quantum field theory at finite temperature (in particular, within the context of superconductivity).
Exploration of the consequences of noncommutative geometry in the search for the unification of the fundamental interactions (M-theory and superstrings, quantum gravity).

On the unification of gauge coupling constants

In the standard model version of the grand unified theory different gauge couplings intend to, but do not, meet at some higher scale. Here we will look for some better ways for the unification of the gauge coupling constants.

Quantum Gravity and the Cosmological Constant

Quantum diffeomorphic gauge invariance and the total cosmological constant, inclusive of the quantum fluctuations of the gravitational field

Topology and Non-Perturbative Gauge Dynamics

The connections between topology in space(time) and in field configuration space and the non-perturbative dynamics of general gauge theories, inclusive of mass generating mechanims, are being studied.

Past projects

Deformation of quantum dynamics in Phase Space

In this project, we study a deformation of the path integral introducing a new time scale. This deformation is inspired by Klauder's path integral construction using a Riemannian metric on phase space. The introduction of this new time scale leads to a complex Landau problem, non commutative geometry and non unitarity effects.

Gauge Phase Space Symmetries and Their Interactions

The potential of gauging phase space dynamical symmetries as a principle for generating interactions is explored

Superconductivity in extremal regimes and nanoscopic particle detectors

Theoretical and experimental study of superconductivity in extremal regimes (spatial and temporal, and in the presence
of electric fields), aiming towards the development of nanoscopic particle detectors

External collaborators: Vincent Bayot (CERMIN, UCL).

The Fuzzy Ball

We are beginning to investigate the possibility of using finite sized matrices to describe a non-commutative three dimensional ball.

The Laplace and Dirac operators on the Fuzzy Grassmanians

This project is concerned with the construction the polarization tensors for (some of) the Fuzzy Grassmanians. We will then consider the Dirac operator and spinors for these spaces in the compact formalism recently introduced for the complex projective spaces. We will also consider Formula: 0 structures.

Weak and strong CP violations

Weak interaction contributions to the strong $\theta$ parameter are revisited in the frame of a large-$N_c$ Chiral Perturbation Theory. Focusing on the hadronic $\eta^{(\prime)}\rightarrow \pi \pi$ amplitudes, we express these second-order corrections in terms of the CP-violating parameter in $K \rightarrow \pi \pi$ decays.
