Axionic tunneling from a topological Kondo insulator
Saikat Banerjee, Anuva Aishwarya, Fei Liu +4
Discoveries over the past two decades have revealed the remarkable ability of quantum materials to emulate relativistic properties of the vacuum, from Dirac cones in graphene to th…
Critical fluctuations and conserved dynamics in a strange ferromagnetic metal
Jin Zhan, Yongjun Zhang, Jiawen Zhang +9
The origin of the strange metallic behavior observed in a wide range of quantum materials is an open challenge to condensed matter physics. Historically, strange metals were unique…
Breakdown of Stoner Ferromagnetism by Intrinsic Altermagnetism
Chen Lu, Chao Cao, Huiqiu Yuan +2
The Stoner criterion for ferromagnetism arises from interaction-driven asymmetric filling of spin bands, requiring that the spin susceptibility: (i) peaks dominantly at $\mathbf{Q}…
Resolving the Thermal Paradox: Many-body localization or fractionalization?
Saikat Banerjee, Piers Coleman
Thermal measurements of heat capacity and thermal conductivity in a wide range of insulators and superconductors exhibit a ``thermal paradox": a large linear specific heat reminisc…
