Electrons imitating light: Frustrated supercritical collapse in charged arrays on graphene
Jiong Lu, Hsin-Zon Tsai, Alpin N. Tatan +10
The photon-like electronic dispersion of graphene bestows its charge carriers with unusual confinement properties that depend strongly on the geometry and strength of the surroundi…
Electric field-induced Skyrmion distortion and giant lattice rotation in the magnetoelectric insulator Cu2OSeO3
J. S. White, K. Prša, P. Huang +9
Uniquely in Cu2OSeO3, the Skyrmions, which are topologically protected magnetic spin vortex-like objects, display a magnetoelectric coupling and can be manipulated by externally ap…
Theory of magneto-electric susceptibility in multiferroic chiral magnets
Ye-Hua Liu, Jung Hoon Han, A. A. Omrani +2
We present a theoretical examination of the magneto-electric response in the recently discovered multiferroic insulator CuOSeO. Combining Monte Carlo simulation and Ginzbur…
Exploration of the helimagnetic and skyrmion lattice phase diagram in Cu2OSeO3 using magnetoelectric susceptibility
A. A. Omrani, J. S. White, K. Prša +6
Using SQUID magnetometry techniques, we have studied the change in magnetization versus applied ac electric field, i.e. the magnetoelectric (ME) susceptibility dM/dE, in the chiral…
Possible spin-orbit driven spin-liquid ground state in the double perovskite phase of Ba3YIr2O9
Tusharkanti Dey, A. V. Mahajan, R. Kumar +4
We report the structural transformation of hexagonal Ba3YIr2O9 to a cubic double perovskite form (stable in ambient conditions) under an applied pressure of 8GPa at 1273K. While th…
Electric-field control of the skyrmion lattice in Cu2OSeO3
J. S. White, I. Levatić, A. A. Omrani +8
Small-angle neutron scattering has been employed to study the influence of applied electric (E-) fields on the skyrmion lattice in the chiral lattice magnetoelectric Cu2OSeO3. In a…
Magnetic hour-glass dispersion and its relation to high-temperature superconductivity in iron-tuned FeTeSe
N. Tsyrulin, R. Viennois, E. Giannini +5
High-temperature superconductivity remains arguably the largest outstanding enigma of condensed matter physics. The discovery of iron-based high-temperature superconductors has ren…
