Successive gliding of twinning disconnections(TDs)creates three-dimensional twins in parent crystal and accommodates shear deformation.It is generally recognized that TD is subject to the same Peierls stress as it gli...

Most topological insulators(TIs)discovered today in spinful systems can be transformed from topological semimetals(TSMs)with vanishing bulk gap via introducing the spin-orbit coupling(SOC),which manifests the intrinsi...

A hallmark of low-temperature plasticity in body-centered cubic(BCC)metals is its departure from Schmid’s law.One aspect is that non-glide stresses,which do not produce any driving force on the dislocations,may affec...
