Instabilities of a U(1) quantum spin liquid in disordered non-Kramers pyrochlores

Benton, Owen

Understand

Quantum spin liquids (QSLs) are exotic phases of matter exhibiting long-range entanglement and supporting emergent gauge fields.

  • A vigorous search for experimental realizations of these states has identified several materials with properties hinting at QSL physics.
  • A key issue in understanding these QSL candidates is often the interplay of weak disorder of the crystal structure with the spin liquid state.
  • It has recently been pointed out that in at least one important class of candidate QSLs - pyrochlore magnets based on non-Kramers ions such as Pr$^{3+}$ or Tb$^{3+}$- structural disorder can actually promote a $U(1)$ QSL ground state.
