Spin excitations in the two-dimensional strongly coupled dimer system malachite
E. Canevet, B. Fak, R. K. Kremer +7
The mineral malachite, Cu2(OD)2CO3, has a quantum spin-liquid ground state and no long-range magnetic order down to at least T=0.4 K. Inelastic neutron scattering measurements show…
Bad-metal behavior reveals Mott quantum criticality in doped Hubbard models
J. Vucicevic, D. Tanaskovic, M. Rozenberg +1
Bad-Metal (BM) behavior featuring linear temperature dependence of the resistivity extending to well above the Mott-Ioffe-Regel (MIR) limit is often viewed as one of the key unreso…
Non-Fermi-Liquid Behavior in Metallic Quasicrystals with Local Magnetic Moments

Motivated by the intrinsic non-Fermi-liquid behavior observed in the heavy-fermion quasicrystal $\mbox{Au}_{51}\mbox{Al}_{34}\mbox{Yb}_{15}$, we study the low-temperature behavior…
The Phase Diagram of the Fractional Quantum Hall Effect: Effects of Landau Level Mixing and Non-Zero Width
Kiryl Pakrouski, Michael R. Peterson, Thierry Jolicoeur +3
Interesting non-Abelian states, e.g., the Moore-Read Pfaffian and the anti-Pfaffian, offer candidate descriptions of the fractional quantum Hall state. But the significant…
Evidence for hidden fermion that triggers high-temperature superconductivity in cuprates
Shiro Sakai, Marcello Civelli, Masatoshi Imada
In superconductors, electrons bound into Cooper pairs conduct a dissipationless current. The strength of the Cooper pairs scales with the value of the critical transition temperatu…

We report Cl NMR, ESR, SR and specific heat measurements on the frustrated kagomé magnet kapellasite, CuZn(OH)Cl, where a gapless spin liquid phas…
Order by Disorder and Energetic Selection of the Ground State in the XY Pyrochlore Antiferromagnet Er2Ti2O7. An Inelastic Neutron Scattering Study
S. Petit, J. Robert, S. Guitteny +6
Examples of materials where an "order by disorder" mechanism is at play to select a particular ground state are scarce. It has recently been proposed, however, that the antiferroma…
