Charge order-driven nematicity in the nickel-pnictide superconductor BaSrNiAs
Thomas Johnson, Camille Bernal-Choban, Sangjun Lee +8
Nematic order refers to the spontaneous breaking of rotational symmetry while preserving translational symmetry. First identified in classical liquid crystals, nematic order arises…
In-plane anisotropy of charge density wave fluctuations in 1-TiSe
Xuefei Guo, Anshul Kogar, Jans Henke +17
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…
Ultrafast renormalization of the onsite Coulomb repulsion in a cuprate superconductor
Denitsa R. Baykusheva, Hoyoung Jang, Ali A. Husain +14
Ultrafast lasers are an increasingly important tool to control and stabilize emergent phases in quantum materials. Among a variety of possible excitation protocols, a particularly…
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…
Search for order near a forbidden Bragg position in BiSrCaCuO with resonant soft x-ray scattering
Xuefei Guo, Sangjun Lee, Thomas A. Johnson +13
Identifying what broken symmetries are present in the cuprates has become a major area of research. Many authors have reported evidence for so-called "" order that involv…
Multiple charge density waves and superconductivity nucleation at antiphase domain walls in the nematic pnictide BaSrNiAs
Sangjun Lee, John Collini, Stella X. -L. Sun +6
How superconductivity interacts with charge or nematic order is one of the great unresolved issues at the center of research in quantum materials. BaSrNiAs$_{2}…
