Hydrostatic pressure studies on non-superconducting UTe2

M. O. Ajeesh, Joe D. Thompson, Eric D. Bauer +3

We report the temperature-pressure phase diagram of a UTe $_{2}$ single crystal that does not undergo a bulk superconducting transition but shows filamentary superconductivity with a…

Non-linear magnons and exchange Hamiltonians of delafossite proximate quantum spin liquids

A. O. Scheie, Y. Kamiya, Hao Zhang +20

Quantum spin liquids (QSL) are theoretical states of matter with long-range entanglement and exotic quasiparticles. However, they generally elude quantitative theory, rendering the…
