Relativistic and nonrelativistic spin splitting above and below the Fermi level in a -wave altermagnet
Nicholas Dale, Omar A. Ashour, Marc Vila +8
Nonrelativistic spin splitting (NRSS) challenges conventional wisdom about antiferromagnets by allowing spin-split electronic bands even in collinear orders with zero net magnetiza…
On the effects of strain, defects, and interactions on the topological properties of HfTe5
Na Hyun Jo, Omar A. Ashour, Zhixue Shu +7
Topological insulators are characterized by spin-momentum-locked massless surface states which are robust under various perturbations. Manipulating such surface states is a topic o…
Theoretical investigation of decoherence channels in athermal phonon sensors
Thomas F. Harrelson, Ibrahim Hajar, Omar A. Ashour +1
The creation and evolution of nonequilibrium phonons is central in applications ranging from cosmological particle searches to decoherence processes in qubits. However, the fundame…
Femtosecond laser induced structural dynamics and melting of Cu (111) single crystal. An ultrafast time-resolved x-ray diffraction study
Runze Li, Omar A. Ashour, Jie Chen +2
Femtosecond, 8.04 KeV x-ray pulses are used to probe the lattice dynamics of 150 nm Cu (111) single crystal on mica substrate irradiated with 400 nm, 100 fs laser pulses. For pump…
