Bell nonlocality from twisted statistics
Ivana Đorđević, Jovan Potrebić, Aleksandra Gočanin +1
We investigate Bell correlations for a free real quantum scalar field on the noncommutative Moyal plane. Although the free field dynamics and the one-particle sector remain unchang…
Twisted holographic superconductors in external magnetic field
Jovan Potrebić, Dragoljub Gočanin
Among the various applications of the AdS/CFT correspondence in condensed matter physics, the realization of the phase transition between the normal and superconducting phases in h…
Rotating frames from quantum deformed spacetime
Dušan Đorđević, Dragoljub Gočanin
In a sense of deformation quantization, noncommutative (NC) geometry introduces a quantum structure of spacetime. Using the twist-deformation formalism, we show that the dynamical…
The role of torsion in holographic conductivity
Dušan Đorđević, Ivana Đorđević, Aleksandra Gočanin +1
Generalizing the usual setup for holographic duality, where bulk spacetime is described by pseudo-Riemannian geometry, we consider a Riemann-Cartan bulk with non-trivial torsion as…
Boundary terms, branes and AdS/BCFT in first-order gravity
Dušan Đorđević, Dragoljub Gočanin
We provide an account of the issue of Gibbons-Hawking-York-like boundary terms for a gravity theory defined on a Riemman-Cartan spacetime. We further discuss different criteria for…
Testing the Braneworld Theory with Identical Particles
Ivana Stojiljković, Dušan Đorđević, Aleksandra Gočanin +1
Various attempts to go beyond the theory of General Relativity start from the assumption that spacetime is not a 4-dimensional but rather a higher-dimensional manifold. Among other…
Holographic Aspects of Even-Dimensional Topological Gravity
Dušan Đorđević, Dragoljub Gočanin
In an odd-dimensional spacetime, gravity can be formulated as a proper gauge theory based on the Chern-Simons action for a suitable gauge group. Performing dimensional reduction, o…
Noncommutative Gauge Theory of Gravity
Marija Dimitrijević Ćirić, Dušan Đorđević, Dragoljub Gočanin +2
Topological gravity (in the sense that it is metric-independent) in a -dimensional spacetime can be formulated as a gauge field theory for the AdS gauge group by a…
Page Curve for Eternal Schwarzschild Black Hole in Dimensionally-Reduced Model of Dilaton Gravity
Stefan Djordjević, Aleksandra Gočanin, Dragoljub Gočanin +1
As a contribution to the subject of the information loss paradox in (1+1)-dimensional gravitational systems, we study a model of (1+1)-dimensional dilaton gravity derived from the…
Microscopic derivation of Dirac composite fermion theory: Aspects of noncommutativity and pairing instabilities
Dragoljub Gočanin, Sonja Predin, Marija Dimitrijević Ćirić +2
Building on previous work [N. Read, Phys. Rev. B 58, Z. Dong and T. Senthil, 16262 (1998); Phys. Rev. B 102, 205126 (2020)] on the system of bosons at filling factor , we der…
Bell's theorem for trajectories
Dragoljub Gočanin, Aleksandra Dimić, Flavio Del Santo +1
In classical theory, the trajectory of a particle is entirely predetermined by the complete set of initial conditions via dynamical laws. Based on this, we formulate a no-go theore…
Canonical Deformation of SUGRA
Dragoljub Gočanin, Voja Radovanović
It is known that one can define a consistent theory of extended, anti-de Sitter (AdS) Supergravity (SUGRA) in . Besides the standard gravitational part, this theory invo…
Noncommutative Electrodynamics from Model of Noncommutative Gravity
Marija Dimitrijević Ćirić, Dragoljub Gočanin, Nikola Konjik +1
In our previous work we have constructed a model of noncommutative (NC) gravity based on gauge symmetry. In this paper we extend the model by adding matter fields:…
Dirac field and gravity in NC model
Dragoljub Gočanin, Voja Radovanović
Action for the Dirac spinor field coupled to gravity on noncommutative (NC) Moyal-Weyl space-time is obtained without prior knowledge of the metric tensor. We emphasise gauge origi…
