We report measurements of anisotropic triple- charge density wave (CDW) fluctuations in the transition metal dichalcogenide 1-TiSe over a large volume of reciprocal space…
Charge Order Evolution of Superconducting BaNi2As2 Under High Pressure
John Collini, Daniel J. Campbell, Daniel Sneed +5
BaNiAs, a non-magnetic superconductor counterpart to BaFeAs, has been shown to develop nematic order, multiple charge orders, and a dramatic six-fold enhancement of…
Absence of precursor incommensurate charge order in electronic nematic Ba0.35Sr0.65Ni2As2
John Collini, Sangjun Lee, Stella X. -L. Sun +5
Recent discoveries of charge order and electronic nematic order in the iron-based superconductors and cuprates have pointed towards the possibility of nematic and charge fluctuatio…
Origin of the 30 T transition in CeRhIn in tilted magnetic fields
