DOI: 10.1038/ncomms15119
Abstract: Layered 5d transition iridium oxides, Sr2(Ir,Rh)O4, are described as unconventional Mott insulators with strong spin-orbit coupling. The undoped compound, Sr2IrO4, is a nearly ideal two-dimensional pseudospin-1/2 Heisenberg antiferromagnet, similarly to the insulating parent compound of… read more here.

DOI: 10.1038/s41567-020-0927-4
Abstract: The mystery of the hidden-order phase in the correlated electron paramagnet URu2Si2 is still unsolved. To address this problem, one strategy is to search for clues in the subtle competition between this state and neighbouring… read more here.

DOI: 10.1080/14786435.2016.1235294
Abstract: Abstract Electrical resistivity measurements were performed as functions of temperature, magnetic field, and angle between the magnetic field and the c-axis of a URuSi single crystal. The resistivity exhibits a two-fold oscillation as a function… read more here.

DOI: 10.1103/physreva.99.043808
Abstract: We study the dynamics of nonlinear photonic lattices driven by two-photon parametric processes. By means of matrix-product-state--based calculations, we show that a quantum many-body state with long-range hidden order can be generated from the vacuum.… read more here.

DOI: 10.1103/physrevb.95.104440
Abstract: We present a comprehensive set of elastic and inelastic neutron scattering measurements on a range of Fe-doped samples of $\mathrm{U}{({\mathrm{Ru}}_{1\ensuremath{-}x}{\mathrm{Fe}}_{x})}_{2}{\mathrm{Si}}_{2}$ with $0.01\ensuremath{\le}x\ensuremath{\le}0.15$. All of the samples measured exhibit long-range antiferromagnetic order, with the size of… read more here.

DOI: 10.1103/physrevb.99.235101
Abstract: Time reversal symmetry and magnetoelastic correlations are probed by means of high-resolution volume dilatometry in URu2Si2 at cryogenic temperatures and magnetic fields more than enough to suppress the hidden order state at H_HO(T = 0.66… read more here.

DOI: 10.1103/physrevlett.119.180402
Abstract: We show that, whereas spin-1/2 one-dimensional U(1) quantum-link models (QLMs) are topologically trivial, when implemented in ladderlike lattices these models may present an intriguing ground-state phase diagram, which includes a symmetry protected topological (SPT) phase… read more here.
