This review discusses instabilities of the Fermi-liquid state of conduction electrons in metals
with particular emphasis on magnetic quantum critical points. Both existing theoretical …

Intermetallic compounds containing f-electron elements display a wealth of superconducting
phases, which are prime candidates for unconventional pairing with complex order …

In the approximately four years since the first review on this subject appeared, a large
amount of additional work—both experimental and theoretical—has been accomplished in …

The roles of critical valence fluctuations of Ce and Yb are discussed as a key origin of
several anomalies observed in Ce-and Yb-based heavy fermion systems. Recent …

Transport, magnetic, and thermal properties at high magnetic fields (H) and low
temperatures (T) of the heavy-fermion compound CeAuSb 2 are reported. At H= 0 this …

The mechanism of how critical end points of the first-order valence transition (FOVT) are
controlled by a magnetic field is discussed. We demonstrate that critical temperature is …

The heavy fermion systems present a unique platform in which strong electronic correlations
give rise to a host of novel, and often competing, electronic and magnetic ground states …

The first heavy fermion superconductor CeCu 2 Si 2 has not revealed all its striking
mysteries yet. At high pressures, superconductivity is supposed to be mediated by valence …

We report on the doping-induced antiferromagnetic state and Fermi-liquid state that are
connected by a superconducting region in a series of CeIrIn 5− x Hg x, CeIrIn 5− x Sn x, and …

The phase diagram of the quasi-2D Ce (Ir, Rh) In 5 system contains two distinct
superconducting domes. By the thermal transport measurements in rotating magnetic fields …
