ABSTRACT: We prove that the stationary NUVO scalar transport equation λ 2 ∇ η 2 ψ+( 2 ∇ η lnλ⋅ ∇ η + ∇ η 2 lnλ )ψ=0 is gauge-equivalent, under ψ=ϕ/λ , to a Schrödinger eigenproblem ( − ℏ 2 2m Δ+ V ...

This repository contains the code and data for the paper Many-body perturbation theory vs. density functional theory: a systematic benchmark for band gaps of solids, published in npj Computational ...

Black hole quasinormal modes arise as eigenmodes of a non-normal Hamiltonian and consequently they do not obey orthogonality relations with respect to commonly used inner products, for example, the ...

Is this real life? Is this just fantasy? A growing number of scientists are suggesting that the idea that we are all living in a simulation may not be completely far-fetched. Simulation theory is the ...

This section details the second-order eigenvector perturbation theory used in our improved analysis of the ESPRIT algorithm, with technical proofs in the appendix.

ABSTRACT: We establish quantum circuit complexity as a fundamental physical observable and prove that it satisfies an uncertainty relation with energy, analogous to Heisenberg’s canonical uncertainty ...

Cold non-baryonic dark matter appears to make up 85% of the matter and 25% of the energy in our universe. However, we don’t yet know what it is. As the opening of many research proposals state, “The ...
