A note on the effects of magnetic field on holographic fermions with dipole-like coupling
Sayan Chakrabarti, Debaprasad Maity, Wadbor Wahlang
In this note, we study the effects of non-zero magnetic field on the fermion spectral function coupled with a non-minimal coupling in the background of a dyonic black hole.…
Studying the holographic Fermi surface in the scalar induced anisotropic background
Sayan Chakrabarti, Debaprasad Maity, Wadbor Wahlang
Holographic properties of a finite density fermion system have been shown to exhibit many interesting behaviours which can be observed in future. In this paper, we study low energy…
Probing the Holographic Fermi Arc with scalar field: Numerical and analytical study
Sayan Chakrabarti, Debaprasad Maity, Wadbor Wahlang
Fermi arcs are disconnected contour of Fermi surface, which can be observed in the pseudo-gap phase of high temperature superconductors. Aiming to understand this pseudo-gap phenom…
Proof of universality of electrical conductivity at finite chemical potential
Sayan K. Chakrabarti, Shankhadeep Chakrabortty, Sachin Jain
It was proposed in arXiv:1008.2944 that, for certain gauge theories with gravity duals, electrical conductivity at finite chemical potential is universal. Here we provide a general…
Scalar field dynamics in warped AdS_3 black hole background
Sayan K. Chakrabarti, Pulak Ranjan Giri, Kumar S. Gupta
We study the normal modes of a scalar field in the background of a warped AdS_3 black hole which arises in topologically massive gravity. We discuss the normal mode spectrum using…
Normal mode analysis for scalar fields in BTZ black hole background
Sayan K Chakrabarti, Pulak Ranjan Giri, Kumar S. Gupta
We analyze the possibility of inequivalent boundary conditions for a scalar field propagating in the BTZ black hole space-time. We find that for certain ranges of the black hole pa…
