Quantum critical behavior in Ce(FeRu)Ge: the full story
Wouter Montfrooij, Tom Heitmann, Yiming Qiu +7
Systems with embedded magnetic ions that exhibit a competition between magnetic order and disorder down to absolute zero can display unusual low temperature behaviors of the resist…
Direct observation of the Higgs amplitude mode in a two-dimensional quantum antiferromagnet near the quantum critical point
Tao Hong, Masashige Matsumoto, Yiming Qiu +12
Spontaneous symmetry-breaking quantum phase transitions play an essential role in condensed matter physics. The collective excitations in the broken-symmetry phase near the quantum…
Identification of the low-energy excitations in a quantum critical system
Tom Heitmann, Jagat Lamsal, Shannon Watson +4
We have identified low-energy magnetic excitations in a doped quantum critical system by means of polarized neutron scattering experiments. The presence of these excitations could…
