Characteristic signatures of quantum criticality driven by geometrical frustration

Geometrical frustration describes situations where interactions are incompatible with the lattice geometry and stabilizes exotic phases such as spin liquids. Whether geometrical frustration of magnetic interactions in metals can induce unconventional quantum critical points is an active area of research. We focus on the hexagonal heavy fermion metal CeRhSn, where the Kondo ions are located on d...

Quantum criticality in CeRh0.58Ir0.42In5: Kondo-breakdown and spin-density critical points

Charge and entropy transport properties of the heavy-fermion compound CeRh0.58Ir0.42In5 were measured as a function of pressure. At atmospheric pressure, local moments in the compound order antiferromagnetically below TN=3.5 K, and coexisting superconductivity develops below T on c =1.04 K. Applying pressure suppresses magnetic order, but a potential quantum-critical point is hidden by a dome o...

Topological Analysis and Quantum Mechanical Structure of C4 and C5 Pure Carbon Clusters

Two bonding models i.e cumullenic and acetylenic models have been proposed to account for thebonding patterns in linear carbon clusters while the bonding patterns in cyclic and 3D geometrieS of theseclusters have remained ambiguous.This work presents the bonding patterns in various C4 and C5 pure clusters at MP2/aug-cc-pVTZ level oftheory. This subject is studied in the light of modern bonding ...
