Metallic Ferromagnetism in the Kondo Lattice

Seiji J. Yamamoto, Qimiao Si

Metallic magnetism is both ancient and modern, occurring in such familiar settings as the lodestone in compass needles and the hard drive in computers. Surprisingly, a rigorous the…

Magnetothermodynamics of the Ising Antiferromagnet Dy2Ge2O7

X. Ke, M. L. Dahlberg, E. Morosan +3

We report systematic low temperature measurements of the DC magnetization, AC susceptibility, and heat capacity of dysprosium pyrogermanate (Dy2Ge2O7) single crystal and powder sam…

Finite Size Scaling of Classical Long-Ranged Ising Chains and the Criticality of Dissipative Quantum Impurity Models

Stefan Kirchner, Qimiao Si, Kevin Ingersent

Motivated in part by quantum criticality in dissipative Kondo systems, we revisit the finite-size scaling of a classical Ising chain with 1/r^{2-epsilon} interactions. For 1/2<epsi…

Quantum Criticality out of Equilibrium: Steady State in a Magnetic Single-Electron Transistor

Stefan Kirchner, Qimiao Si

Quantum critical systems out of equilibrium are of extensive interest, but are difficult to study theoretically. We consider here the steady state limit of a single electron transi…

Quantum Criticality in Heavy Fermion Metals

Philipp Gegenwart, Qimiao Si, Frank Steglich

Quantum criticality describes the collective fluctuations of matter undergoing a second-order phase transition at zero temperature. Heavy fermion metals have in recent years emerge…
