Conditional value-at-risk under reward-penalty mechanism with applications to robust portfolio management
Jun Cai, Tiantian Mao, Zhiqiao Song
In this paper, we present robust portfolio selection models by incorporating a reward and penalty mechanism into portfolio management. We assume that the joint distribution of the…
First-principles prediction of chiral-phonon-induced orbital accumulation
A. Pezo, A. Manchon, Y. Nii +2
Chiral phonons offer a route to transfer angular momentum without relying on magnetic order, but their electronic response in metals remains poorly understood from perspectives bey…
