Laser-Induced Transient Magnons in Sr3Ir2O7 Throughout the Brillouin Zone
D. G. Mazzone, D. Meyers, Y. Cao +32
Although ultrafast manipulation of magnetism holds great promise for new physical phenomena and applications, targeting specific states is held back by our limited understanding of…
Giant Spin Gap and Magnon Localization in the Disordered Heisenberg Antiferromagnet Sr2Ir1-xRuxO4
Yue Cao, Xuerong Liu, Wenhu Xu +15
We study the evolution of magnetic excitations in the disordered two-dimensional antiferromagnet Sr2Ir1-xRuxO4. A gigantic magnetic gap greater than 40 meV opens at x = 0.27 and in…
Ultrafast energy and momentum resolved dynamics of magnetic correlations in photo-doped Mott insulator SrIrO
M. P. M. Dean, Yue Cao, X. Liu +32
Measuring how the magnetic correlations throughout the Brillouin zone evolve in a Mott insulator as charges are introduced dramatically improved our understanding of the pseudogap,…
First-order melting of a weak spin-orbit Mott insulator into a correlated metal
Tom Hogan, Z. Yamani, D. Walkup +7
The electronic phase diagram of the weak spin-orbit Mott insulator (Sr(1-x)Lax)3Ir2O7 is determined via an exhaustive experimental study. Upon doping electrons via La substitution,…
Reconciliation of local and long range tilt correlations in underdoped La2-xBaxCuO4
Emil S. Bozin, Ruidan Zhong, Kevin R. Knox +4
A long standing puzzle regarding the disparity of local and long range CuO6 octahedral tilt correlations in the underdoped regime of La2-xBaxCuO4 is addressed by utilizing compleme…
Evidence for Fluctuating Charge Stripes far above the Charge-Ordering Transition in La Sr NiO
A. M. Milinda Abeykoon, Emil S. Božin, Wei-Guo Yin +4
The temperature evolution of structural effects associated with charge (CO) and spin order (SO) in LaSrNiO has been investigated using neutron powder diffra…
