Emergent vacua and stability constraints on black hole solutions in higher-dimensional gravity
Nicolás Trullols Sandino, Andrei Galiautdinov
We investigate static spherically symmetric vacuum solutions in higher-dimensional gravity, beginning with the five-dimensional Starobinsky model governed by the action $f(R…
Logarithmically enhanced hyperbolic square-root deformation of Starobinsky inflation
Andrei Galiautdinov
We propose an enhanced hyperbolic square-root (HSQRT) deformation of the Starobinsky model in the context of gravity. The original HSQRT construction provided a globally reg…
Globally stable, ghost-free hyperbolic square-root deformation of the Starobinsky model
Andrei Galiautdinov
We propose an exact, analytic deformation of the Starobinsky model governed by the strictly positive derivative of its Lagrangian, , with . T…
Exotic spherically-symmetric Lambda-vacuum in the four-dimensional Starobinsky model
Andrei Galiautdinov
We introduce an exact, two-parameter family of static, spherically-symmetric, constant-curvature -vacuum solutions within the four-dimensional Starobinsky model…
Modified Fronsdal coordinates for maximally extended Schwarzschild spacetime
Andrei Galiautdinov
We introduce a coordinate system that complements the Kruskal--Szekeres extension. Like the standard construction, it covers the maximally extended Schwarzschild manifold in its en…
Quantum deliberating machines
Andrei Galiautdinov
Within the familiar circuit-based quantum computational setting, we introduce and analyze a toy model of a quantum physical device capable of internal, self-referential deliberatio…
Simulating kaon mixing with Josephson phase qubits
Andrei Galiautdinov
Superconducting circuits with Josephson junctions distinguish themselves from other types of quantum computing architectures by having easily controllable metastable computational…
Canonical quantization of the dark positive-energy Dirac field and time asymmetry
Andrei Galiautdinov
We perform canonical quantization of the single-component, spin-zero field that was introduced by Dirac in 1971 and recently suggested as a candidate for dark matter by Bogomolny.…
Positive-energy Dirac particles in cosmology
Andrei Galiautdinov
We provide general relativistic treatment of the single-component field described by Dirac's positive-energy wave equation of 1971. It is motivated by Bogomolny's proposal to regar…
