Concentration for Coulomb gases and Coulomb transport inequalities [PDF]
Journal of Functional Analysis, 2018 We study the non-asymptotic behavior of Coulomb gases in dimension two and more. Such gases are modeled by an exchangeable Boltzmann-Gibbs measure with a singular two-body interaction. We obtain concentration of measure inequalities for the empirical distribution of such gases around their equilibrium measure, with respect to bounded Lipschitz and ...

Coulomb and Riesz gases: The known and the unknown [PDF]
Journal of Mathematics and Physics, 2022 We review what is known, unknown, and expected about the mathematical properties of Coulomb and Riesz gases. Those describe infinite configurations of points in [Formula: see text] interacting with the Riesz potential ±| x|− s (respectively, −log | x ...

Tuning electron correlation in magic-angle twisted bilayer graphene using Coulomb screening [PDF]
Science, 2020 Tuning the interactions Elucidating the nature of the superconducting state in magic-angle twisted bilayer graphene (MATBG) has proven tricky. To study the role of electron-electron correlations in this state, Liu et al.

A Critical Look at Coulomb Counting Approach for State of Charge Estimation in Batteries
Energies, 2021 In this paper, we consider the problem of state-of-charge estimation for rechargeable batteries. Coulomb counting is a well-known method for estimating the state of charge, and it is regarded as accurate as long as the battery capacity and the beginning ...

Peculiarity of the Coulombic criticality? [PDF]
Physics Letters A, 1998 We indicate that Coulombic systems could correspond to Wilson effective Hamiltonians similar to that of the ordinary (nonionic) fluids but with a negative $ϕ^4$-coefficient. In that case, solving the ``exact'' renormalization group equation in the local potential approximation, we show that close initial Hamiltonians may lead either to a first order ...

Ionic Coulomb blockade as a fractional Wien effect [PDF]
Nature Nanotechnology, 2019 Recent advances in nanofluidics have allowed the exploration of ion transport down to molecular-scale confinement, yet artificial porins are still far from reaching the advanced functionalities of biological ion machinery.

, 2020 Learning the true density in high-dimensional feature spaces is a well-known problem in machine learning. In this work, we consider generative autoencoders based on maximum-mean discrepancy (MMD) and provide theoretical insights. In particular, (i) we prove that MMD coupled with Coulomb kernels has optimal convergence properties, which are similar to ...

ON THE EVOLUTION OPERATOR KERNEL FOR THE COULOMB AND COULOMB-LIKE POTENTIALS [PDF]
Modern Physics Letters A, 1996 With the help of the Schwinger-DeWitt expansion analytical properties of the evolution operator kernel for the Schrödinger equation in time variable t are studied for the Coulomb and Coulomb-like potentials (which becomes 1/|q| as |q|→0). It turned out that the Schwinger-DeWitt expansion for them is divergent. So, the kernels for these potentials have
