Complexified quasinormal modes and the pole-skipping in a holographic system at finite chemical potential
Navid Abbasi, Sara Tahery
We develop a method to study coupled dynamics of gauge-invariant variables, constructed out of metric and gauge field fluctuations on the background of a AdS Reissner-Nordström…

A comparison of condensate mass of QCD vacuum between Wilson line approach and Schwinger effect
Sara Tahery, Liping Zou, Xurong Chen
By duality approach, we study condensate mass of QCD vacuum via dilaton wall background in presence of parameter which represents the gluon condensation in holographic set up.…

Conditions for vacuum instability in holographic theories with dilaton field
Sara Tahery, Sreeraj Nair, Pengming Zhang
We investigate the vacuum instability in the presence of dilaton field in a holographic set up. Although the dilaton is a bulk field, it leads to the vacuum instability on the boun…
