Square-Root Price Impact Is Necessary for Endogenous Manipulation Cycles in Learning-Agent Markets
Yang Zhou, Jianwen Chen, Ruipeng Wei
We study a minimal agent-based market in which a single evolutionary-optimized institutional agent interacts with 20{,}000 herding retail traders. The agent spontaneously discovers…
Order Splitting and Liquidity Replenishment Are Jointly Necessary for the Square-Root Law of Market Impact:
Yang Zhou, Jianwen Chen, Ruipeng Wei
Three quantitative predictions have been advanced for the square-root law (SRL) of market impact, with : GGPS (), FGLW (),…
Non-Hermitian Skin Effect Enhances Pairing Correlations in Moiré Hubbard Systems
Yang Zhou, Jianwen Chen, Ruipeng Wei
We show that the non-Hermitian skin effect (NHSE) can enhance pairing correlations in moiré Hubbard systems through a channel-selective mechanism: skin-induced localization amplif…
Flat-Band Stoner Instability and Peierls-Phase Origin of the Transdimensional Anomalous Hall Effect in Rhombohedral Graphite
Yang Zhou
A ``transdimensional'' anomalous Hall effect (TDAHE), where both in-plane ($\Bpar$) and out-of-plane magnetic fields produce hysteretic Hall signals, was recently observed in nine-…
