Charge order-driven nematicity in the nickel-pnictide superconductor Ba $_{1 - x}$ Sr $_{x}$ Ni $_{2}$ As $_{2}$

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 $T$ -TiSe $_{2}$

Xuefei Guo, Anshul Kogar, Jans Henke +17

We report measurements of anisotropic triple- $q$ charge density wave (CDW) fluctuations in the transition metal dichalcogenide 1 $T$ -TiSe $_{2}$ over a large volume of reciprocal space…

Incommensurate magnetic orders and topological Hall effect in the square-net centrosymmetric EuGa $_{2}$ Al $_{2}$ system

Jaime M. Moya, Shiming Lei, Eleanor M. Clements +16

Neutron diffraction on the centrosymmetric square-net magnet EuGa $_{2}$ Al $_{2}$ reveals multiple incommensurate magnetic states (AFM1,2,3) in zero field. In applied field, a new magnet…

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…

Multiple charge density waves and superconductivity nucleation at antiphase domain walls in the nematic pnictide Ba $_{1 - x}$ Sr $_{x}$ Ni $_{2}$ As $_{2}$

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. Ba $_{1 - x}$ Sr $_{x}$ Ni $_{2}$ As$_{2}…

Evidence for photoinduced sliding of the charge-order condensate in La $_{1.875}$ Ba $_{0.125}$ CuO $_{4}$

Matteo Mitrano, Sangjun Lee, Ali A. Husain +13

We use femtosecond resonant soft x-ray scattering to measure the ultrafast optical melting of charge-order correlations in La $_{1.875}$ Ba $_{0.125}$ CuO $_{4}$ . By analyzing both the en…
