DOI: 10.1002/adma.202402373
Abstract: One of the exotic expectations in the 2D curved spacetime is the geometric potential from the curvature of the 2D space, still possessing unsolved fundamental questions through Dirac quantization. The atomically thin 2D materials are… read more here.

DOI: 10.1007/jhep02(2025)197
Abstract: The physical and mathematical properties of charged black holes that are linearly coupled to charged massive scalar fields are studied analytically. In particular, we prove that, in the eikonal large-mass regime Mμ ≫ 1, the… read more here.

DOI: 10.1007/jhep05(2025)118
Abstract: Unlike a classical charged bosonic field, a classical charged fermion field on a static charged black hole does not exhibit superradiant scattering. We demonstrate that the quantum analogue of this classical process is however present.… read more here.

DOI: 10.1007/s10773-018-3856-6
Abstract: Christodoulou and Rovelli have revealed that black holes have big interiors that grow asymptotically linearly with advanced time. Even if the Hawking radiation is taken into account, such interiors remain large. Based on these findings,… read more here.
