*** December 3, Workshop on strong dynamics beyond QCD, invited speaker.
***November 27, New preprint: Timelike entanglement entropy is a new complex measure of information, holographically realized through an appropriate combination of spacelike and timelike extremal surfaces. This measure is highly sensitive to Lorentz invariance breaking, with the observable itself encoding valuable information about the stability and naturalness of the underlying theory. This insight offers an optimistic prospect for the emergence of the time coordinate as a timelike quantum information-theoretic property. Furthermore, the pseudoentropy identifies Fermi surfaces either through the logarithmic behavior of its real part or, alternatively, via its constant imaginary part, providing a novel interpretation of the pseudoentropy’s imaginary component.

*** April 1, New research preprint with our group postdocs M. Afrasiar, J.K. Basak. We propose a holographic formalism for a timelike entanglement entropy in non-conformal theories. This pseudoentropy is a complex-valued measure of information, receives contributions from a set of spacelike surfaces and a finite timelike bulk surface with mirror symmetry, which can merge naturally on the IR tip of our confining spatially compactified geometry. Moreover, we find that the timelike entanglement entropy exhibits unique behavior in confining theories, making it a probe of confinement and phase transitions. In this work we also discuss the entanglement entropy in Euclidean spacetime in confining theories.
*** March 15, New research preprint with A. Kehagias(NTUA), A. Riotto(Geneva U.). Using the Penrose limit on the photon ring we can construct a universal formalism to zoom in and study the photon ring physics. For a large class of axisymmetric black holes we find universally the correspondence of the quasinormal modes of the black hole with the photon ring geodesics. Additionally we discuss the possibility of photon rings serving as holographic horizons in a holographic duality framework for astrophysical black holes and we propose an upper classical bound on the Lyapunov exponent of the photon ring null geodesics.

We also introduce for first time the time-like entanglement entropy in Lifshitz theories.

The scaling, depends on the asymptotic geometric conditions of the theory, even in cases where the boundary is asymptotically AdS. This also implies that the suppression of heavy mesons in strongly coupled plasmas depends on the direction, and in principle are possible very different and non-continuously related scalings in the suppression.

*** 3 December, New preprint on the chaotic motion of particles near black holes. The Lyapunov coefficient for certain types of motion near the black holes is naturally dependent on the inaffinity on the black hole horizons. With the help of the generalized surface gravity we defined, we argue that in general there is no reason for the Lyapunov exponent of classical trajectories to be bounded in generic spacetimes with horizon. The existence of a bound depends on the particular system. Moreover, there is no distinction by the Lyapunov exponent between maximal chaos of black hole and cosmological horizons.

*** 27 October, New preprint on the holography at large dimensions with N. Pappas and N. Toumbas. The large d limit creates a localized potential in the near horizon regime resulting in a simplification of the analysis for the non-local observables, while at the same time retaining their qualitative physical properties. Moreover, the extrapolation to low and intermediate dimensions shows good quantitative agreement with the numerical analysis. The large d limit may be used as a tool for the study and (in)validation of the renormalization group monotonicity theorems.

We map features of the 2-dim σ-model spectrum expanded on a non-trivial massive vacuum, to a classical particle Hamiltonian with variable mass. We show that the integrability of the classical particle system, implies the factorization of the S-matrix in the dual quantum 2-dim theory. The equivalence we propose initiates the study of analytic non-integrability techniques on the S-matrix vacua in relation to factorization, and could open new interesting directions of the applicability of those techniques, which go beyond the classification of integrable structures that are mainly used to day.

We find the necessary and sufficient conditions for monotonicity along the RG of the c-function for a generic theory. It is possible to impose these conditions only on the boundary UV data of the theory and they will guarantee, for a well defined theory, at least one monotonic c-function along the RG flow.

We also extract the physical critical exponents of the system by Machine Learning!

In a similar way, the Brownian motion analysis can be studied in such a way to accommodate a wide class of theories.
