A micromechanical analysis of intergranular stress corrosion cracking of an irradiated austenitic stainless steel
D. Liang, J. Hure, A. Courcelle +2
Irradiation Assisted Stress Corrosion Cracking (IASCC) is a material degradation phenomenon affecting austenitic stainless steels used in nuclear Pressurized Water Reactors (PWR),…
A new collective phenomenon arising from spin anisotropic perturbations to a Heisenberg square lattice manifested in paramagnetic resonance experiments
S. Cox, R. D. McDonald, J. Singleton +6
We report unexpected behaviour in a family of Cu spin- 1/2 systems, in which an apparent gap in the low energy magneto-optical absorption spectrum opens at low temperature. This pr…
Thermal entanglement of qubit pairs on the Shastry-Sutherland lattice
S. El Shawish, A. Ramsak, J. Bonca
We show that temperature and magnetic field properties of the entanglement between spins on the two-dimensional Shastry-Sutherland lattice can be qualitatively described by analyti…
In-Gap Spin Excitations and Finite Triplet Lifetimes in the Dilute Singlet Ground State System SrCu(2-x)Mgx(BO3)2
S. Haravifard, S. R. Dunsiger, S. El Shawish +4
High resolution neutron scattering measurements on a single crystal of SrCu(2-x)Mgx(BO3)2 with x=0.05 reveal the presence of new spin excitations within the gap of this quasi-two d…
Spin-polaron excitations in a doped Shastry-Sutherland model
S. El Shawish, J. Bonca
Using variational algorithm on an infinite Shastry-Sutherland (SS) lattice we show that the introduction of a static nonmagnetic impurity into a dimerized ground state leads to a f…
Dynamic Spin Structure Factor of SrCu2(BO3)2 at Finite Temperatures
S. El Shawish, J. Bonca, I. Sega
Using finite temperature Lanczos technique on finite clusters we calculate dynamical spin structure factor of the quasi-two-dimensional dimer spin liquid SrCu2(BO3)2 as a function…
