First-Principles Wannier Representation of Proximity Effects
Yaroslav Zhumagulov, Johan Félisaz, Stepan S. Tsirkin +2
The paper introduces a first‑principles method to construct a dynamical proximity operator from density functional theory, allowing exact downfolding of heterostructure Hamiltonian…
Electronic properties and topological aspects of graphene nanohelicoids
Xiaoqian Liu, Arsen Herasymchuk, Yaroslav Zhumagulov +1
The paper introduces graphene nanohelicoids—helically wrapped graphene nanoribbons—and uses tight‑binding calculations to show that their electronic band structures exhibit width‑d…
Charge carrier flow through trimmed graphene nanoribbon junctions
Julien Leuenberger, KristiÄns ÄerÅeviÄs, Oleg V. Yazyev
As Moore's law approaches its fundamental limits, the development of nanoelectronic devices using low-dimension materials has become a promising avenue for further miniaturization…
Single-ion anisotropy-stabilized short-period helimagnetism in frustrated chiral CoTeO
Priya R. Baral, Ravi Yadav, Victor Ukleev +12
Chiral spin textures in magnetic insulators promise magneto-electric (ME) spintronics with orders-of-magnitude lower power consumption than metallic systems. However, realizing the…
Quantum Criticality in Monolayer Amorphous Carbon
Rejaul SK, Hanning Zhang, Artem K Grebenko +15
Amorphous solids represent the extreme limit of broken translational symmetry, in which the absence of long-range order removes well-defined crystal momenta and invalidates the Blo…
Coupling between CaWO phonons and Er dopants
Mikhael T. Sayat, Federico Pisani, Hin Lok Chang +8
We investigate the lattice dynamics of CaWO, a promising host crystal for erbium-based quantum memories, using inelastic neutron scattering together with density-functional per…
