Local covariant quantum field theory over spectral geometries
, 2004 A framework which combines ideas from Connes' noncommutative geometry, or spectral geometry, with recent ideas on generally covariant quantum field theory, is proposed in the present work.

The existence of singularities and the origin of space-time
Zagadnienia Filozoficzne w Nauce, 2008 Methods of noncommutative geometry are applied to deal with singular space-times in general relativity. Such space-times are modeled by noncommutative von Neumann algebras of random operators.

Self Sustained Traversable Wormholes Induced by Gravity’s Rainbow and Noncommutative Geometry
EPJ Web of Conferences, 2013 We compare the effects of Noncommutative Geometry and Gravity’s Rainbow on traversable wormholes which are sustained by their own gravitational quantum fluctuations. Fixing the geometry on a well tested model, we find that the final result shows that the

Observables and dispersion relations in κ-Minkowski spacetime
Journal of High Energy Physics, 2017 We revisit the notion of quantum Lie algebra of symmetries of a noncommutative spacetime, its elements are shown to be the generators of infinitesimal transformations and are naturally identified with physical observables.

Noncommutative geometrical structures of entangled quantum states
, 2010 We study the noncommutative geometrical structures of quantum entangled states. We show that the space of a pure entangled state is a noncommutative space.

Balanced Metrics and Noncommutative Kähler Geometry
Symmetry, Integrability and Geometry: Methods and Applications, 2010 In this paper we show how Einstein metrics are naturally described using the quantization of the algebra of functions C^∞(M) on a Kähler manifold M. In this setup one interprets M as the phase space itself, equipped with the Poisson brackets inherited ...

B-decay anomalies and scalar leptoquarks in unified Pati-Salam models from noncommutative geometry
Journal of High Energy Physics, 2018 Motivated by possible scalar-leptoquark explanations of the recently reported B-decay anomalies, we investigate whether the required leptoquarks can be accommodated within models based on noncommutative geometry (NCG).
