Strain Anisotropy Driven Spontaneous Formation of Nanoscrolls from Two-Dimensional Janus Layers
Mohammed Sayyad, Ying Qin, Jan Kopaczek +12
Two-dimensional Janus transition metal dichalcogenides (TMDs) have attracted attention due to their emergent properties arising from broken mirror symmetry and self-driven polarisa…
Roton-like mode in solid He-4
E. Blackburn, S. K. Sinha, C. Broholm +3
Recent theoretical and experimental work on solid He-4 has focused on vacancies, or other lattice defects and whether these can form a Bose-Einstein condensate within the solid. Th…
Absence of low temperature anomaly in the Debye-Waller factor of solid He-4
E. Blackburn, J. M. Goodkind, S. K. Sinha +6
The mean square atomic displacement in hcp-phase solid He-4 has been measured in crystals with a molar volume of 21.3 cm^3. It is temperature independent from 1 K to 140 mK, with n…
A 4-unit-cell superstructure in optimally doped YBa2Cu3O6.92 superconductor
Zahirul Islam, X. Liu, S. K. Sinha +8
Using high-energy diffraction we show that a 4-unit-cell superstructure, q0=(1/4,0,0), along the shorter Cu-Cu bonds coexists with superconductivity in optimally doped YBCO. A comp…
X-Ray-Diffraction Study of Charge-Density-Waves and Oxygen-Ordering in YBa2Cu3O6+x Superconductor
Zahirul Islam, S. K. Sinha, D. Haskel +5
We report a temperature-dependent increase below 300 K of diffuse superlattice peaks corresponding to q_0 =(~2/5,0,0) in an under-doped YBa_2Cu_3O_6+x superconductor (x~0.63). Thes…
The Structure of Nanoscale Polaron Correlations in La1.2Sr1.8Mn2O7
B. J. Campbell, R. Osborn, D. N. Argyriou +7
A system of strongly-interacting electron-lattice polarons can exhibit charge and orbital order at sufficiently high polaron concentrations. In this study, the structure of short-r…
