• Research Activity The references in this part are given in the ‘List of Publications’ below.  Space-time deformed symmetries. Two connected aspects of my work concern the development of field theory within the formalism of non-commutative geometry and the quantization of 3D gravity in the case of non-vanishing cosmological constant. In both cases, Hopf algebras structures play a fundamental role. In [26, 27] we investigated the possibility of semi-classical gravity modifications due to Planck–scale deformation of space–time symmetries, whose implementation leads to the study of non–commutative field theory. I studied the emergence of quantum group (a class of Hopf algebras) structures and their application in the quantization of 3D gravity from the implementation of Loop Quantum Gravity (LQG) techniques in [13, 18, 20, 22, 25]. A synthesis of these two lines of research has recently been achieved in [8], where deformed quantum space-time symmetries have been shown to arise from first principles.  Black hole microscopic degrees of freedom. An important part of my research activity concerns the quantum description of the microscopic degrees of freedom of a black hole horizon and the derivation of its entropy. Quantization techniques were applied to a local definition of black hole, encoded in the notion of ‘isolated horizon’, to describe the quantum horizon microstates for the spherically symmetric case in [24], and to a wider class of distorted and rotating isolated horizons respectively in [23] and [15]. In [21] a detailed analytic counting of the entropy within this framework has been performed, showing how to recover the leading linear area term in the Bekenstein-Hawking entropy formula together with a logarithmic sub-leading term. All these results are reviewed in the invited contribution [19]. In the works [11, 14] the black hole entropy derivation was improved by eliminating extra semiclassical inputs and ambiguities present in the standard calculation performed in previous literature. In [16, 17] I described the black hole evaporation process from a local quantum gravity perspective, implementing the near horizon quantum dynamics and deriving potentially observable effects in the radiation spectrum. Furthermore, I applied these results to investigate the singularity resolution and implications for the information paradox. In the joint collaboration [6], we used a gravitational analog of the Schwinger effect, due to gravity tidal force, and the properties of the renormalized stress-energy tensor of test scalar field to investigate which region the Hawking quanta come from. The result that most of the thermal spectrum originates well outside the horizon can have important implications in the discussion of the information and firewall paradox, as well as of the trans-planckian problem. With the same co-authors, I have investigated in [5] how the presence of torsion degrees of freedom affects the thermodynamical derivation of Einstein equation presented in the seminal work of Jacobson, Phys. Rev. Lett. 75, 1260 (1995). Interestingly, this analysis led to a generalized Hartle–Hawking tidal heating term for black holes with contributions coming from torsion which imply a different output of gravitational waves w.r.t. to what expected in General Relativity, and thus having possible implications for future observations. More recently, in [3], [1] a formalism was developed to construct a kinematical Hilbert space describing the quantum geometry of a spherically symmetric black hole, where the symmetry reduction is imposed at the quantum level. The main result of this investigation is the derivation of an effective Hamiltonian that can be used to solve for quantum black hole geometries by evolving classical black hole initial data sets. This is one of the main lines of my current research and it is described more in detail in my research statement.  Quantum gravity condensates. Another focus of my research interests has been the construction, within the Group Field Theory approach, of quantum gravity condensate (vacuum) states in order to describe macroscopic, spatially homogeneous geometries. Such construction is motivated by the idea of a statistical mechanical treatment of fundamental space-time degrees of freedom approach (i.e. an ‘hydrodynamical’ treatment) to study the continuum limit of the theory, one of the main open problems in the field. In the joint collaboration [10], we have constructed generalized quantum gravity condensate states to model homogenous, continuum geometries with different topologies, of relevance for application to cosmology and black holes. This work represented the starting point for the derivation of holographic properties for continuum, semi-classical horizons obtained in [9, 4].  Edge modes and CFT structures. An interesting new approach to the problem of dynamics in quantum gravity is based on the investigation of the new physical degrees of freedom that arise in presence of a boundary and the central role of conformal field theory (CFT) in their description. The introduction of a boundary requires the specification of boundary conditions in order for the action principle to be well defined and the symplectic potential to be conserved and closed, breaking gauge invariance at the boundary and turning gauge transformations into symmetry transformations. However, this standard treatment has the limitation that it can prevent us from obtaining a well defined canonical structure for all the generators of the boundary symmetry, represented by soft charges. The new idea is that, in the presence of the boundary, the phase space of gauge and gravity theories needs to be extended by edge modes, which are conjugated to the soft charges. This extension is needed in order to account for the proper calculation of entanglement entropy, as well as to preserve gauge invariance in the presence of boundaries, allowing one to clearly understand that boundary symmetries are true symmetries associated to gauge invariant observables. I have applied this new treatment in the context of gravity [7, 12] and electromagnetism [2], in both cases yielding a central charge in the algebra of the boundary symmetry generators. This approach opens the way to a geometrical, unified characterization of matter degrees of freedom as well as to a new description of quantum gravity dynamics in terms of a bulk/boundary correspondence. Moreover, it may lead to a cross-fertilization of techniques and ideas coming from string theory, AdS/CFT and entanglement entropy. This line of investigation is also part of my research proposal. • Publications
