Charge density wave (CDW) is an important concept in condensed matter physics, germane
to a number of physical phenomena. But the origin of CDW is still under debate, partly …

This review is an up-to-date snapshot of the current situation in studies of materials with
competing electron spectrum instabilities, namely Cooper pairing, on the one hand, and …

Strong electron correlations are at the heart of many physical phenomena of current interest
to the condensed matter community. Here we present a survey of the mechanisms …

Quantum critical points (QCPs), at which a second-order phase transition is continuously
suppressed to zero temperature, are currently one of the central topics in solid-state …

This review article explains the fundamental idea, basic theories, desired properties, and
material realizations of superconductors in a pedagogical manner. Organic …

The magnetic susceptibility χ, heat capacity, and electrical resistivity ρ under pressure have
been measured on La 3 Ni 2 O 7 and La 4 Ni 3 O 10. Heat-capacity measurements reveal …

One-dimensional (1D) systems persist as some of the most interesting because of the rich
physics that emerges from constrained degrees of freedom. A desirable route to harness the …

We prepared a new two-dimensional oxyantimonide, BaTi 2 Sb 2 O, which shows a
superconducting transition at 1.2 K, representing the first superconductivity in a system with …

The temperature dependence of electrical resistivity and magnetic susceptibility was studied
for RPt2Si2 compounds with R= Y, La, Nd, and Lu. LaPt2Si2 and NdPt2Si2 show steps in …

We report the investigations of specific heat, thermal conductivity, as well as thermoelectric
power on the charge-density-wave (CDW) compound Lu 5 Ir 4 Si 10 as a function of …
