چکیده
We study the black hole interiors in holographic Weyl semimetals and nodal line semimetals. find that singularities are of Kasner form. In topologically nontrivial phase at low temperature, both exponents metric fields proper time from horizon to singularity almost constant, likely reflecting topological nature also some specific behaviors inside each semimetal model.

Quantum effects in black hole interiors.
The Weyl curvature inside a black hole formed in a generic collapse grows, classically without bound, near to the inner horizon, due to partial absorption and blueshifting of the radiative tail of the collapse. Using a spherical model, we examine how this growth is modified by quantum effects of conformally coupled massless fields.
متن کاملSemiclassical effects in black hole interiors
First-order semiclassical perturbations to the Schwarzschild black hole geometry are studied within the black hole interior. The source of the perturbations is taken to be the vacuum stress-energy of quantized scalar, spinor, and vector fields, evaluated using analytic approximations developed by Page and others (for massless fields) and the DeWitt-Schwinger approximation (for massive fields). ...
متن کاملNumerical investigation of black hole interiors
Gravitational perturbations which are present in any realistic stellar collapse to a black hole, die off in the exterior of the hole, but experience an infinite blueshift in the interior. This is believed to lead to a slowly contracting lightlike scalar curvature singularity, characterized by a divergence of the hole’s (quasi-local) mass function along the inner horizon. The region near the inn...
متن کاملNumerical Black Hole Interiors and String Cosmology Initial Conditions
Recent work has proposed the principle of ‘asymptotic past triviality’ to characterize the initial state in the pre-big bang scenario of string cosmology, that it is a generic perturbative solution of the low-energy effective action. Among the more generic sets of solutions which is simple enough to investigate thoroughly, yet complex enough to exhibit interesting behavior, is the gravitydilato...
متن کاملTopological Superconductivity in Dirac Semimetals.
Dirac semimetals host bulk band-touching Dirac points and a surface Fermi loop. We develop a theory of superconducting Dirac semimetals. Establishing a relation between the Dirac points and the surface Fermi loop, we clarify how the nontrivial topology of Dirac semimetals affects their superconducting state. We note that the unique orbital texture of Dirac points and a structural phase transiti...
