Cone-Size Dependence of Jet Suppression in Heavy-Ion Collisions
(Journal article; Peer reviewed, 2021)The strong suppression of high-pT jets in heavy-ion collisions is a result of elastic and inelastic energy loss suffered by the jet multiprong collection of color charges that are resolved by medium interactions. Hence, ... -

Geometric Frustration on the Trillium Lattice in a Magnetic Metal-Organic Framework
(Journal article; Peer reviewed, 2022)In the dense metal-organic framework Na[Mn(HCOO)3], Mn2+ ions (S=52) occupy the nodes of a “trillium” net. We show that the system is strongly magnetically frustrated: the Néel transition is suppressed well below the ... -
