Geometric criterion for solvability of lattice spin systems
- Physics, MathematicsPhysical Review B
We present a simple criterion for solvability of lattice spin systems on the basis of the graph theory and the simplicial homology. The lattice systems satisfy algebras with graphical…
Large Spin Hall Magnetoresistance in Antiferromagnetic α−Fe2O3/Pt Heterostructures

Competition between intermediate plaquette phases in SrCu2 ( BO3)2 under pressure
- PhysicsPhysical Review B
Building on the growing evidence based on NMR, magnetization, neutron scattering, ESR, and specific heat that, under pressure, SrCu$_2$(BO$_3$)$_2$ has an intermediate phase between the dimer and the…
Dynamic Multiferroicity of a Ferroelectric Quantum Critical Point.
- Medicine, PhysicsPhysical review letters
An elevated magnetic response of a ferroElectric near the ferroelectric quantum critical point (FE QCP), since magnetic fluctuations are entangled with ferro Electric fluctuations, is demonstrated and it is suggested that any ferro electric quantumcritical point is an inherent multiferroic quantum critical Point.
Intimate link between charge density wave, pseudogap and superconducting energy scales in cuprates
- PhysicsNature Physics
The cuprate high-temperature superconductors develop spontaneous charge density wave (CDW) order below a temperature TCDW and over a wide range of hole doping (p). An outstanding challenge in the…
Observation of chiral solitons in the quantum spin liquid phase of LiCuVO$_4$
- Materials Science, Physics
Quantum spin liquids represent a magnetic ground state arising in the presence of strong quantum fluctuations that preclude ordering down to zero temperature and leave clear fingerprints in the…
Theory of the intermediate phase of SrCu_2(BO_3)_2 under pressure
Building on the NMR evidence that two different Cu sites are present in the intermediate phase of SrCu_2(BO_3)_2 under pressure, and on recent neutron scattering experiments, we investigate the…
