Evidence of intertwined pair density and charge density wave orders in UTe2
Zhen Zhu, Yudi Huang, Julian May-Mann +9
The strongly correlated spin-triplet superconductor UTe2 hosts an unusual landscape of magnetic-field-sensitive charge density wave (CDW) phases, positioning it as a compelling sys…
Vestigial Nematic Order at Zero Temperature in Two-Dimensional Frustrated Quantum Antiferromagnets
Matthew C. O'Brien, Eduardo Fradkin
The phase diagram of the two-dimensional quantum - Heisenberg antiferromagnet on a square lattice is a long-standing open problem. Despite recent advances in numerical te…
Superconducting States and Intertwined Orders in Metallic Altermagnets
Xuan Zou, Rafael M. Fernandes, Eduardo Fradkin
Altermagnets are a newly identified class of magnets with nodal spin-split band structures, providing a fertile platform for studying unconventional superconductivity and intertwin…
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…
Intertwined Orders and the Physics of High Temperature Superconductors
Eduardo Fradkin
Complex phase diagrams are generic feature of quantum materials that display high temperature superconductivity. In addition to d-wave superconductivity (or other unconventional st…
Vortex flow anisotropy in nematic superconductors
F. Castillo Menegotto, R. S. Severino, P. D. Mininni +4
We investigate the vortex flow anisotropy in the mixed state of nematic superconductors, focusing on the effects of nematic-superconducting coupling on vortex dynamics. Using numer…
