Deterministic Realization of Classical Dissipation on Quantum Computers

Muhammad Idrees Khan, Sauro Succi, Hua-Dong Yao · 2026

Lattice Boltzmann (LB) on quantum devices must reconcile unitary gate evolution with the dissipative \emph{collision} step. In the multiple-relaxation-time (MRT) class, we work in the common setting o…

Distributional Statistical Models: Weak Moments, Cumulants, and a Central Limit Theorem

R. Labouriau · 2026

Many important statistical models fall outside classical moment-based methods due to the non-existence of moments or moment generating functions. We propose a generalised probabilistic framework in wh…

Kramers-Kronig Relations and Causality in Non-Markovian Open Quantum Dynamics: Kernel, State, and Effective Kernel

Kejun Liu · 2026

Kramers-Kronig (KK) relations are usually invoked for causal response functions, but their precise status for non-Markovian quantum memory kernels is less explicit. We separate three Laplace-domain ob…

A criterion for proving entropy chaos on path space

Luigi Borasi, Francesco Carlo De Vecchi, Stefania Ugolini · 2026

A criterion for proving a strong form of propagation of chaos on the path space, known as entropy chaos, for a general interacting diffusion system is proposed. Our analysis focuses on the class of co…

Classification of Epileptic iEEG using Topological Machine Learning

Sunia Tanweer, Narayan Puthanmadam Subramaniyam, Firas A. Khasawneh · 2026

Epileptic seizure detection from EEG signals remains challenging due to the high dimensionality and nonlinear, potentially stochastic, dynamics of neural activity. In this work, we investigate whether…
