Causality, Redshift, and Matching-Scale Cancellation for Reflective Black-Hole Horizons
Masahiro Kaminaga
The Boltzmann flux reflectivity used in quantum-horizon models does not by itself define a causal black-hole boundary response. We study two related questions for stationary Schwar…
Optimal Sample Exponents for Direct Discrete-Gaussian SVP Search on Haar Random Lattices
Masahiro Kaminaga
We determine the optimal sample exponent for direct discrete Gaussian SVP search on Haar random unimodular lattices, counting zero outputs. The output is one sampled vector, option…
Collective Onset of Matter-Induced Scalarization around a Black Hole with Two Thin Shells
Masahiro Kaminaga
We study the linear onset of matter-induced scalarization for a static black hole surrounded by two spatially separated thin matter shells. We assume that the conformal matter coup…
Thermal Concentration and Poisson-Dirichlet Edge Statistics for Random-Lattice Gibbs Ensembles
Masahiro Kaminaga
We study Gibbs measures on high-dimensional Haar-random unimodular lattices, where the energy of a lattice vector is its squared Euclidean norm. The random lattice is viewed as que…
Black-Hole Echo Resonance Spectra and Source Dependence in a Controlled Transfer-Function Model
Masahiro Kaminaga
Echo models phenomenologically encode possible near-horizon structure by replacing the purely ingoing horizon-side condition with an effective reflecting inner boundary near the wo…
Strong-disorder expansion of the root-averaged density of states for the Anderson model on the Bethe lattice
Masahiro Kaminaga
We study the root-averaged density of states for the Anderson model on the Bethe lattice in the strong-disorder regime. Here the density of states means the root-averaged spectral…
Determinant Formulas for Scattering Matrices of Schrödinger Operators with Finitely Many Concentric -Shells
Masahiro Kaminaga
We study stationary scattering for Schrödinger operators in with finitely many concentric --shell interactions of constant real strengths. Starting from the self--…
Schrödinger operators with concentric --shell interactions
Masahiro Kaminaga
We study Schrödinger operators on with finitely many concentric spherical -shell interactions. The operators are defined by the quadratic form method and are descr…
