Soft charges and zero modes at null boundaries
Dušan Đorđević, Olivera Miskovic, Antonia Montecinos +1
Asymptotic symmetries at null boundaries provide a powerful window into the soft sector of field theories, revealing conserved charges and infinite-dimensional symmetry algebras be…
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…
Comment on "Geometry of the Grosse-Wulkenhaar model"
Dragan Prekrat
We clarify a key point in the geometric reinterpretation of the Grosse$\unicode{x2013}$Wulkenhaar (GW) model proposed in "Geometry of the Grosse-Wulkenhaar model" [JHEP 03 (2010) 0…
Pinpointing Triple Point of Noncommutative Matrix Model with Curvature
Dragan Prekrat, Benedek Bukor, Juraj Tekel
We study a Hermitian matrix model with a quartic potential, modified by a curvature term , where is a fixed external matrix. Inspired by the truncated Heisen…
Diffusion and instabilities in large-N holographic Fermi liquids: the vector fluctuations of the electron star
Vladan Gecin, Mihailo Čubrović
We study the hydrodynamic response of the AdS electron star in the vector sector, and compute the correlation functions and the transverse conductivity of the dual field theory. Th…
