In conventional superconductors gauge symmetry is broken, while in unconventional superconductors other symmetries may also be broken. There has recently been a great deal of...

PrOs4Sb12 is a 1.85 K superconductor. Its superconductivity shows unconventional behavior, and the originating mechanism remains unknown. One characteristic is an internal...

In some materials, the onset of superconductivity is accompanied by the spontaneous appearance of small magnetic fields. This is a signature of broken time-reversal-symmetry...

This proposal plans to investigate the destruction of superconductivity by inter-band scattering in Lu_2Fe_3Si_5 doped by Y and Dy. Recent muon spin rotation studies have shown...

Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a...

The discovery of superconductivity in ThCr2Si2 type tetragonal Fe-based compounds (i.e. YFe2Ge2) have generated considerable interest. Recently we found bulk superconductivity...

The first discovered heavy fermion superconductor CeCu2Si2 had been believed to have d-wave pairing symmetry for many years. However, recent experiments on CeCu2Si2 discovered...

In SrHo2O4, the Ho3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, this gives rise to geometric...

After the discovery of multiband superconductivity in MgB2 (Tc = 39.7 K) a number of studies have been made to understand the origin of superconductivity in this compound as...

The ternary intermetallics, which crystallise in the ThCr2Si2 structure, have been extensively studied mainly because these materials offer a rich variety of exotic ground...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

In superconductors, the inversion symmetry of the crystallographic structure plays a central role in the formation of the Cooper pairs. The intermetallic compounds La7Pd3 and...

In recent work Moessner and colleagues have demonstrated that thermally induced defects in spin ice behave as emergent magnetic monopoles. Within the material there exist...

Recent investigations of physical properties of ACo2As2 (A = Ca, Sr, Ba) indicate that Co-based arsenides could be a potential parent compound like the parent AFe2As2. While...

This proposal is part of our project to investigate the unusual physics of 5d transition metal oxides. In particular, we are studying two samples of the chemical composition...

Non-centrosymmetric superconductors (NCS) are believed to be good candidates for unconventional superconductivity. In particular, there is the possibility of Cooper pairs with...
