We present the full phase diagram of dumbbell model spin ice as a function temperature, chemical potential and staggered which breaks translational lattice symmetry in favour charge crystal ordering. observe double winged structure with five possible phases, monopole fluid (spin ice), fragmented single phases crystal, zinc blend structure. Our provides skeleton for liquid-liquid transitions structures observed itinerant magnets under pressure external field. relate our results to recent...
The Mott insulator Ca$_2$RuO$_4$ exhibits a rare insulator-to-metal transition (IMT) induced by DC current. While structural changes associated with this have been tracked neutron diffraction, Raman scattering, and x-ray spectroscopy, work on elucidating the response of electronic degrees freedom is still in progress. Here we unveil current-induced modifications states employing angle-resolved photoemission spectroscopy (ARPES) conjunction four-probe transport. Two main effects emerge: clear...
