Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

open access: yesAdvanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Designing a two-stage model for the resilient agri-food supply chain network under dynamic competition

British Food Journal, 2023
PurposeSupply chain risk management can effectively reduce the loss of retailers. In this regard, retailers need to consider the competition risks of competitors in addition to the disruption risks.

The Competition Complexity of Dynamic Pricing

Mathematics of Operations Research, 2022
We study the competition complexity of dynamic pricing relative to the optimal auction in the fundamental single-item setting. In prophet inequality terminology, we compare the expected reward [Formula: see text] achievable by the optimal online policy on m independent and identically distributed (i.i.d.) random variables distributed according to F to
