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 …
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 mo…
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…
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…
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.…
