Time-reversal-like degeneracies distinguished by the anomalous Hall effect in a metallic kagome ice compound
Kan Zhao, Yoshi Tokiwa, Hua Chen +1
In magnetic crystals, despite the explicit breaking of time-reversal symmetry, two equilibrium states related by time reversal are always energetically degenerate. In ferromagnets…
Experimental Quantification of Entanglement Through Heat Capacity
H. Singh, T. CHakraborty, D. Das +4
A new experimental realization of heat capacity as an entanglement witness (EW) is reported. Entanglement properties of a low dimensional quantum spin system are investigated by he…
Quantum bicriticality in the heavy-fermion metamagnet YbAgGe
Y. Tokiwa, M. Garst, P. Gegenwart +2
Bicritical points, at which two distinct symmetry-broken phases become simultaneously unstable, are typical for spin-flop metamagnetism. Interestingly, the heavy-fermion compound Y…
Zero-field Quantum Critical Point in CeCoIn
Y. Tokiwa, P. Gegenwart, E. D. Bauer
Quantum criticality in the normal and superconducting state of the heavy-fermion metal CeCoIn is studied by measurements of the magnetic Grüneisen ratio, , and specific he…
Unique phase diagram with narrow superconducting dome in EuFe(AsP) due to Eu local magnetic moments
Y. Tokiwa, S. -H. Hübner, O. Beck +2
The interplay between superconductivity and Eu magnetic moments in EuFe(AsP) is studied by electrical resistivity measurements under hydrostatic pressur…
