Transmission across non-Hermitian -symmetric quantum dots and ladders
Abhiram Soori, M. Sivakumar, V. Subrahmanyam
A non-Hermitian region connected to semi-infinite Hermitian lattices acts either as a source or as a sink and the probability current is not conserved in a scattering typically. Ev…
Nonadiabatic charge pumping across two superconductors connected through a normal metal region by periodically driven potentials
Abhiram Soori, M. Sivakumar
Periodically driven systems exhibit resonance when the difference between an excited state energy and the ground state energy is an integer multiple of times the driving fr…
Consistent Non-Minimal Couplings of Massive Higher-Spin Particles
Ignacio Cortese, Rakibur Rahman, M. Sivakumar
The mutual compatibility of the dynamical equations and constraints describing a massive particle of arbitrary spin, though essential for consistency, is generically lost in the pr…
The Central Charge of the Warped AdS^3 Black Hole
Kumar S. Gupta, E. Harikumar, Siddhartha Sen +1
The AdS/CFT conjecture offers the possibility of a quantum description for a black hole in terms of a CFT. This has led to the study of general AdS^3 type black holes with a view t…
Geometric Finiteness, Holography and Quasinormal Modes for the Warped AdS_3 Black Hole
Kumar S. Gupta, E. Harikumar, Siddhartha Sen +1
We show that there exists a precise kinematical notion of holography for the Euclidean warped black hole. This follows from the fact that the Euclidean warped black…
-deformed Dirac Equation
E. Harikumar, M. Sivakumar, N. Srinivas
We construct a Dirac equation in -Minkowski spacetime and analyse its implications. This -deformed Dirac equation is expanded as a power series involving derivatives with res…
