In the layered iron-based superconductor YFe2Ge2, a high Sommerfeld ratio of order 100 mJ/mol K^2 and a T^3/2 temperature dependence of the electrical resistivity at low...

Quantum phase transitions are abrupt qualitative changes of a system's groundstate occurring only at exactly zero temperature. Such critical points - although never reachable...

Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed...

The proposal requests time to obtain a full mapping of the low-energy acoustic phonons. We have measured an acoustic phonon anomaly associated with the structural transition and...

Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices;the inherent magnetoelectric effect can underpin both pyroelectric or...

Novel functionality in condensed matter physics is continuously attracting huge attention owing to the possible novel future applications including quantum computing, electronic...

Given the controversy about the magnetic ground state of the recently well studied triangular-lattice antiferromagnet (TLA) YbMgGaO4 due to Mg2+/Ga3+ disorder, we have...

Spin fluctuations of materials close to a quantum critical point (QCP) exhibit anomalous behaviors. Sr3Ru2O7 has been shown to exhibit field-induced spin density wave (SDW)...

Quantum spin liquid (QSL) is a long-sought goal of condensed matter physics because of its connection to the microscopic mechanism of high-Tc superconductivity and non-trivial...

Among the intense research on quantum spin liquid states, the Kitaev model has attracted great attention. Compounds consist of honeycomb layers with strong spin-orbit coupling,...

Thermoelectric device is one of the key devices for the sustainable energy technology. Although semiconductor-based devices are widely used, they sometimes contain toxic,...
