Coalitional stability under myopic expectations and externalities
We study coalition formation problems in the presence of externalities, focusing on settings where agents exhibit myopic expectations, that is, they evaluate potential deviations based solely on the immediate outcome, assuming no further reactions or reorganization by others. First, we establish a sufficient condition for the non-emptiness of both the core and the stable set. In the case of the core, our condition for ensuring non-emptiness also provides a characterization of all core partition…

Probing QCD Confinement with Spin Entanglement
Once regarded as mere emptiness, the vacuum is now understood to possess a rich and complex structure, characterized by fluctuating energy fields and a condensate of virtual quark-antiquark pairs. These pairs cause spontaneous chiral symmetry breaking, a fundamental phenomenon that is believed to generate over 99% of the mass in the visible universe. However, the precise mechanism linking the chiral symmetry breaking to the mass generation associated with quark confinement remains one of the mo…
