Probing Neutron Skin through Event-by-Event Pion Asymmetry in Heavy-ion collisions

Xu-Hua Tian, Long-Gang Pang

In this work, we propose a novel approach for probing the neutron skin thickness of gold (Au) by analyzing the event-by-event distribution of $I ¨ ^{-}$ and $I ¨ ^{+}$ yield difference…

Adaptive Preconditioned Gradient Descent with Energy

Hailiang Liu, Levon Nurbekyan, Xuping Tian +1

We propose an adaptive step size with an energy approach for a suitable class of preconditioned gradient descent methods. We focus on settings where the preconditioning is applied…
