Index Theorem in Finite Noncommutative Geometry
, 2007 Index theorem is formulated in noncommutative geometry with finite degrees of freedom by using Ginsparg-Wilson relation. It is extended to the case where the gauge symmetry is spontaneously broken.

Superconformal nets and noncommutative geometry
Journal of Noncommutative Geometry, 2015 This paper provides a further step in the program of studying superconformal nets over S^1 from the point of view of noncommutative geometry. For any such net \mathcal A and any family \Delta

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 ...

Vacuum energy from noncommutative models
Physics Letters B, 2018 The vacuum energy is computed for a scalar field in a noncommutative background in several models of noncommutative geometry. One may expect that the noncommutativity introduces a natural cutoff on the ultraviolet divergences of field theory.

A geometric picture of quantum mechanics with noncommutative values for observables
Results in Physics, 2020 We present here what we consider a new picture of quantum mechanics with the position and momentum observables as coordinates of the usual quantum phase space of a single particle, which also serves as the model of the physical space.
