Following the observation of an anomalous Nernst signal in cuprates, the Nernst effect has
been explored in a variety of metals and superconductors during the past few years. This …

Pressure is a powerful tool for exploring novel phenomena in solid-state physics. We review
the electronic states of single-crystalline EuT2X2 (T: transition metal, X: Si or Ge) and related …

At a generic quantum critical point, the thermal expansion α is more singular than the
specific heat cp. Consequently, the “Grüneisen ratio,” Γ= α/cp, diverges. When scaling …

The Seebeck coefficient of a metal is expected to display a linear temperature dependence
in the zero-temperature limit. To attain this regime, it is often necessary to cool the system …

This article attempts to review our present understanding of nearly-independent-particle
excitations—quasiparticles—in heavy fermion systems. The emphasis is on a realistic, that is …

EuNi2P2 is known as a heavy fermion compound with an electronic specific heat coefficient
γ= 100 mJ/(K2 mol). We grew single crystals and studied their electronic and magnetic …

The link between the metamagnetic transition and novel spin-triplet superconductivity of
UTe2 was discussed thermodynamically through magnetostriction measurements in a …

We give an overview on experimental studies performed in the last 25 years on heavy-
fermion systems in a high magnetic field. The properties of field-induced magnetic …

We study the Loschmidt echo (LE) of a coupled system consisting of a central spin and its
surrounding environment described by a general XY spin-chain model. The quantum …

We analyze several experimental results, obtained at different pressures, on three heavy-
fermion systems using a quantum scaling approach. In spite of the distinct ground states …
