In this letter we analyze the Hamiltonian formulation of the Jackiw-Teitelboim model of 2D gravity and calculate the central charge associated with the asymptotic symmetries, taking care of boundary terms. For black hole solutions, we show that there is no √ 2 discrepancy between the thermodynamical entropy and the statistical one obtained via Cardy’s formula. PACS numbers: 04.20.-q, 04.70.-s, ...

We demonstrate explicitly the absence of quantum corrections to Carroll-Field-Jackiw (CFJ) term beyond one-loop within Lorentz-breaking CPT-odd extension QED. The proof holds two prescriptions calculations, with axial vector in fermion sector {}treated either as a perturbation or contribution exact propagator field.

We consider the entanglement island in a deformed Jackiw-Teitelboim black hole presence of phase transition. This has van der Waals-Maxwell-like structure as it is coupled with Maxwell field. study behavior Page curve this by using paradigm. In fixed charge ensemble, we discuss different situations charges that influence system's structure. There only Hawking-Page transition absence charges, wh...

In low dimensional gravity on anti-de sitter space there exists a possibility that the asymptotic isometry is raised to a Virasoro symmetry living at spatial infinity. We discuss in detail asymptotic isometry of the most general anti-de sitter dilaton gravity in two dimensions. From analysis of the boundary dynamics it turns out that the Virasoro symmetry is not preserved in all the models. Mor...

In this paper, which is the second part in a series of two, we construct tree level baryon exchange and resonance amplitudes for πN/MB-scattering in the framework of the Kadyshevsky formalism. We use this formalism to formally implement absolute pair suppression, where we make use of the method of Takahashi and Umezawa. The resulting amplitudes are Lorentz invariant and causal. We continue stud...
