Isoperimetry and stability properties of balls with respect to nonlocal energies

A Figalli, N Fusco, F Maggi, V Millot… - … in Mathematical Physics, 2015 - Springer
We obtain a sharp quantitative isoperimetric inequality for nonlocal s-perimeters, uniform
with respect to s bounded away from 0. This allows us to address local and global minimality …

On an isoperimetric problem with a competing nonlocal term II: The general case

C Muratov, H Knüpfer - Communications on Pure and Applied …, 2014 - Wiley Online Library
This paper is the continuation of a previous paper (H. Knüpfer and CB Muratov, Comm. Pure
Appl. Math. 66 (2013), 1129–1162). We investigate the classical isoperimetric problem …

Local and Global Minimality Results for a Nonlocal Isoperimetric Problem on

M Bonacini, R Cristoferi - SIAM Journal on Mathematical Analysis, 2014 - SIAM
We consider a nonlocal isoperimetric problem defined in the whole space R^N, whose
nonlocal part is given by a Riesz potential with exponent α∈(0,N-1). We show that critical …

[HTML][HTML] On minimizers of interaction functionals with competing attractive and repulsive potentials

R Choksi, RC Fetecau, I Topaloglu - Annales de l'Institut Henri Poincaré C …, 2015 - Elsevier
We consider a family of interaction functionals consisting of power-law potentials with
attractive and repulsive parts and use the concentration compactness principle to establish …

A compactness lemma and its application to the existence of minimizers for the liquid drop model

RL Frank, EH Lieb - SIAM Journal on Mathematical Analysis, 2015 - SIAM
The ancient Gamow liquid drop model of nuclear energies has had a renewed life as an
interesting problem in the calculus of variations: Find a set Ω⊂R^3 with given volume A that …

Isoperimetric problem with a Coulomb repulsive term

V Julin - Indiana University Mathematics Journal, 2014 - JSTOR
We consider a non-local isoperimetric problem with a repulsive Coulomb term. In dimension
three, this corresponds to Gamow's famous liquid drop model. We show that, whenever the …

Low density phases in a uniformly charged liquid

H Knüpfer, CB Muratov, M Novaga - Communications in Mathematical …, 2016 - Springer
This paper is concerned with the macroscopic behavior of global energy minimizers in the
three-dimensional sharp interface unscreened Ohta–Kawasaki model of diblock copolymer …

Nonlocal shape optimization via interactions of attractive and repulsive potentials

A Burchard, R Choksi, I Topaloglu - Indiana University Mathematics Journal, 2018 - JSTOR
We consider a class of nonlocal shape optimization problems for sets of fixed mass where
the energy functional is given by an attractive/repulsive interaction potential in powerlaw …

The ionization conjecture in Thomas–Fermi–Dirac–von Weizsäcker theory

RL Frank, PT Nam… - Communications on Pure …, 2018 - Wiley Online Library
We prove that in Thomas–Fermi–Dirac–von Weizsäcker theory, a nucleus of charge Z> 0
can bind at most Z+ C electrons, where C is a universal constant. This result is obtained …
