String Memory Effect
Hamid Afshar, Erfan Esmaeili, M. M. Sheikh-Jabbari
In systems with local gauge symmetries, the memory effect corresponds to traces inscribed on a suitable probe when a pure gauge configuration at infinite past dynamically evolves t…
On Complexity of Jackiw-Teitelboim Gravity
Mohsen Alishahiha
Using "complexity=action" proposal we compute complexity for Jackiw-Teitelboim gravity assuming that a UV cutoff enforces us to have a cut off behind the horizon. We find that the…
Magneto-transport in an anomalous fluid with weakly broken symmetries, in weak and strong regime
Navid Abbasi, Armin Ghazi, Farid Taghinavaz +1
We consider a general system with weakly broken time and translation symmetries. We assume the system also possesses a symmetry which is not only weakly broken, but is anoma…
Charged Vector Inflation
Hassan Firouzjahi, Mohammad Ali Gorji, Seyed Ali Hosseini Mansoori +2
We present a model of inflation in which the inflaton field is charged under a triplet of gauge fields. The model enjoys an internal symmetry supporting the isotropic…
Complexity and Behind the Horizon Cut Off
Amin Akhavan, Mohsen Alishahiha, Ali Naseh +1
Motivated by deformation of a conformal field theory we compute holographic complexity for a black brane solution with a cut off using "complexity=action" proposal…
BRST invariant RG flows
Shimasadat Asnafi, Holger Gies, Luca Zambelli
A mass parameter for the gauge bosons in gauge-fixed four-dimensional Yang-Mills theory can be accommodated in a local and manifestly BRST-invariant action. The construction is bas…
