Factorial cumulants of proton multiplicity near a critical point using maximum entropy freeze-out prescription [PDF]
EPJ Web of ConferencesWe present the first application of the maximum-entropy freeze-out prescription to calculate factorial cumulants of proton multiplicities near the conjectured QCD critical point in thermal equilibrium.

Model-Free Forward Screening Via Cumulative Divergence [PDF]
Journal of the American Statistical Association, 2019 Feature screening plays an important role in the analysis of ultrahigh dimensional data. Due to complicated model structure and high noise level, existing screening methods often suffer from model misspecification and the presence of outliers. To address these issues, we introduce a new metric named cumulative divergence (CD), and develop a CD-based ...

Coherent Fluctuations in Noisy Mesoscopic Systems, the Open Quantum SSEP, and Free Probability
Physical Review X, 2023 Quantum coherences characterize the ability of particles to quantum mechanically interfere within some given distances. In the context of noisy many-body quantum systems, these coherences can fluctuate. A simple toy model to study such fluctuations in an

Learning linear non-Gaussian graphical models with multidirected edges
Journal of Causal Inference, 2021 In this article, we propose a new method to learn the underlying acyclic mixed graph of a linear non-Gaussian structural equation model with given observational data.

Entanglement entropies of an interval in the free Schrödinger field theory on the half line
Journal of High Energy Physics, 2022 We study the entanglement entropies of an interval adjacent to the boundary of the half line for the free fermionic spinless Schrödinger field theory at finite density and zero temperature, with either Neumann or Dirichlet boundary conditions.

Journal of High Energy Physics, 2018 In this paper we explain the relation between the free energy of the SYK model for N Majorana fermions with a random q-body interaction and the moments of its spectral density.

Higher Order Moments and Free Cumulants of Complex Wigner Matrices [PDF]
, 2023 The main object of this thesis is a random matrix model known as the Wigner model. We investigate the higher order moments and free cumulants of a complex Wigner matrix.

Functional relations for higher-order free cumulants
, 2021 We establish the functional relations between generating series of higher-order free cumulants and moments in higher-order free probability, solving an open problem posed fifteen years ago by Collins, Mingo, Śniady and Speicher. We propose an extension of free probability theory, which governs the all-order topological expansion in unitarily invariant ...

Self-Dual Criticality in Three-Dimensional Z_{2} Gauge Theory with Matter
Physical Review X, 2021 The simplest topologically ordered phase in 2+1D is the deconfined phase of Z_{2} gauge theory (realized in the toric code, for example). This phase permits a duality that exchanges electric and magnetic excitations (“e” and “m” particles).
