Fluctuations, large deviations and rigidity in hyperuniform systems: a brief survey

S Ghosh, JL Lebowitz - Indian Journal of Pure and Applied Mathematics, 2017 - Springer
We present a brief survey of fluctuations and large deviations of particle systems with
subextensive growth of the variance. These are called hyperuniform (or …

Generalized stealthy hyperuniform processes: maximal rigidity and the bounded holes conjecture

S Ghosh, JL Lebowitz - Communications in Mathematical Physics, 2018 - Springer
We study translation invariant stochastic processes on R^ d R d or Z^ d Z d whose diffraction
spectrum or structure function S (k), ie the Fourier transform of the truncated total pair …

Point processes, hole events, and large deviations: random complex zeros and Coulomb gases

S Ghosh, A Nishry - Constructive Approximation, 2018 - Springer
We consider particle systems (also known as point processes) on the line and in the plane
and are particularly interested in “hole” events, when there are no particles in a large disk (or …

Rigidity of the three-dimensional hierarchical Coulomb gas

S Chatterjee - Probability Theory and Related Fields, 2019 - Springer
A random set of points in Euclidean space is called 'rigid'or 'hyperuniform'if the number of
points falling inside any given region has significantly smaller fluctuations than the …

Determinantal point processes conditioned on randomly incomplete configurations

T Claeys, G Glesner - Annales de l'Institut Henri Poincare (B) …, 2023 - projecteuclid.org
For a broad class of point processes, including determinantal point processes, we construct
associated marked and conditional ensembles, which allow to study a random configuration …

Ground states and hyperuniformity of the hierarchical Coulomb gas in all dimensions

S Ganguly, S Sarkar - Probability Theory and Related Fields, 2020 - Springer
Stochastic point processes with Coulomb interactions arise in various natural examples of
statistical mechanics, random matrices and optimization problems. Often such systems due …

Rigidity hierarchy in random point fields: random polynomials and determinantal processes

S Ghosh, M Krishnapur - Communications in Mathematical Physics, 2021 - Springer
In certain point processes, the configuration of points outside a bounded domain
determines, with probability 1, certain statistical features of the points within the domain. This …

Spectral rigidity of random Schrödinger operators via Feynman–Kac formulas

PY Gaudreau Lamarre, P Ghosal, Y Liao - Annales Henri Poincaré, 2020 - Springer
We develop a technique for proving number rigidity (in the sense of Ghosh and Peres in
Duke Math J 166 (10): 1789–1858, 2017) of the spectrum of general random Schrödinger …

A strong duality principle for equivalence couplings and total variation

AQ Jaffe - Electronic Journal of Probability, 2023 - projecteuclid.org
We introduce and study a notion of duality for two classes of optimization problems
commonly occurring in probability theory. That is, on an abstract measurable space (Ω, F) …

Semigroups for one-dimensional Schrödinger operators with multiplicative Gaussian noise

PYG Lamarre - 2020 - search.proquest.com
A problem of fundamental interest in mathematical physics is that of understanding the
structure of the spectrum of random Schrödinger operators. An important tool in such …
