Break up of heavy fermions at an antiferromagnetic instability
S. Friedemann, S. Wirth, S. Kirchner +7
We present results of high-resolution, low-temperature measurements of the Hall coefficient, thermopower, and specific heat on stoichiometric YbRh2Si2. They support earlier conclus…
Fermi-surface collapse and dynamical scaling near a quantum critical point
Sven Friedemann, Niels Oeschler, Steffen Wirth +6
Quantum criticality arises when a macroscopic phase of matter undergoes a continuous transformation at zero temperature. While the collective fluctuations at quantum-critical point…
Discontinuous Hall coefficient at the quantum critical point in YbRh2Si2
Sven Friedemann, Niels Oeschler, Steffen Wirth +6
YbRh2Si2 is a model system for quantum criticality. Particularly, Hall effect measurements helped identify the unconventional nature of its quantum critical point. Here, we present…
