NONCOMMUTATIVE GEOMETRIES: AN OVERVIEW [PDF]
International Journal of Modern Physics A, 2008 I make a very introductory overview of noncommutative geometries, focusing on the DFR model for Minkowski space; in this model the noncommutativity, or “fuzziness”, of spacetime events emerges at semiclassical level putting together the Heisenberg principle with general relativity.

Wormhole inspired by non-commutative geometry
Physics Letters B, 2015 In the present Letter we search for a new wormhole solution inspired by noncommutative geometry with the additional condition of allowing conformal Killing vectors (CKV).

Zitterbewegung in noncommutative geometry [PDF]
International Journal of Modern Physics A, 2019 We have considered the effects of space and momentum noncommutativity separately on the zitterbewegung (ZBW) phenomenon. In the space noncommutativity scenario, it has been expressed that, due to the conservation of momentum, the Fourier decomposition of the expectation value of position does not change.

MIRROR FERMIONS IN NONCOMMUTATIVE GEOMETRY [PDF]
Modern Physics Letters A, 1998 In a recent paper we pointed out the presence of extra fermionic degrees of freedom in a chiral gauge theory based on Connes' noncommutative geometry. Here we propose a mechanism which provides a high mass to these mirror states, so that they decouple from low energy physics.

On noncommutative geometry of orbifolds [PDF]
Communications in Contemporary Mathematics, 2016 An orbifold is a Morita equivalence class of a proper étale Lie groupoid. A unitary equivalence class of spectral triples over the algebra of smooth invariant functions is associated with any compact spin orbifold. In the case of an effective spin orbifold, we construct a collection of spectral triples over the smooth convolution algebras of the ...

Holographic thermalization in noncommutative geometry
Physics Letters B, 2015 Gravitational collapse of a shell of dust in noncommutative geometry is probed by the renormalized geodesic length, which is dual to probe the thermalization by the two-point correlation function in the dual conformal field theory.

Curvature in noncommutative geometry [PDF]
, 2019 Our understanding of the notion of curvature in a noncommutative setting has progressed substantially in the past ten years. This new episode in noncommutative geometry started when a Gauss-Bonnet theorem was proved by Connes and Tretkoff for a curved noncommutative two torus. Ideas from spectral geometry and heat kernel asymptotic expansions suggest a
