Signatures of exciton condensation in a transition metal dichalcogenide
Anshul Kogar, Melinda S. Rak, Sean Vig +9
Bose condensation has shaped our understanding of macroscopic quantum phenomena, having been realized in superconductors, atomic gases, and liquid helium. Excitons are bosons that…
Influence of domain walls in the incommensurate charge density wave state of Cu intercalated 1-TiSe
Shichao Yan, Davide Iaia, Emilia Morosan +3
We report a low-temperature scanning tunneling microscopy study of the charge density wave (CDW) order in 1-TiSe and CuTiSe. In pristine 1-TiSe we observ…
Observation of a Charge Density Wave Incommensuration Near the Superconducting Dome in CuxTiSe2
Anshul Kogar, Gilberto A. de la Pena, Sangjun Lee +8
X-ray diffraction was employed to study the evolution of the charge density wave (CDW) in CuxTiSe2 as a function of copper intercalation in order to clarify the relationship betwee…
The importance of sigma bonding electrons for the accurate description of electron correlation in graphene
Huihuo Zheng, Yu Gan, Peter Abbamonte +1
Electron correlation in graphene is unique because of the interplay of the Dirac cone dispersion of electrons with long range Coulomb interaction. The random phase approximatio…
