YbRh2Si2: Quantum tricritical behavior in itinerant electron systems
Takahiro Misawa, Youhei Yamaji, Masatoshi Imada
We propose that proximity of the first-order transition manifested by the quantum tricritical point (QTCP) explains non-Fermi-liquid properties of YbRh2Si2. Here, at the QTCP, a co…

Quantum Metamagnetic Transitions Induced by Changes in Fermi-Surface Topology -Applications to a Weak Itinerant-Electron Ferromagnet;ZrZn_2
Youhei Yamaji, Takahiro Misawa, Masatoshi Imada
We clarify that metamagnetic transitions in three dimensions show unusual properties as quantum phase transitions if they are accompanied by changes in Fermi-surface topology. An u…
