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…
Rotating frames from quantum deformed spacetime
DuÅ¡an ÄorÄeviÄ, Dragoljub GoÄanin
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
DuÅ¡an ÄorÄeviÄ, Ivana ÄorÄeviÄ, Aleksandra GoÄanin +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…
Twisted holographic superconductors in external magnetic field
Jovan PotrebiÄ, Dragoljub GoÄanin
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…
Boundary terms, branes and AdS/BCFT in first-order gravity
DuÅ¡an ÄorÄeviÄ, Dragoljub GoÄanin
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…
