Emergent chirality in a polar meron to skyrmion phase transition
Yu-Tsun Shao, Sujit Das, Zijian Hong +10
Polar skyrmions are predicted to emerge from the interplay of elastic, electrostatic and gradient energies, in contrast to the key role of the anti-symmetric Dzyalozhinskii-Moriya…
Transferring Orbital Angular Momentum to an Electron Beam Reveals Toroidal and Chiral Order
Kayla X. Nguyen, Yi Jiang, Michael C. Cao +13
Orbital angular momentum and torque transfer play central roles in a wide range of magnetic textures and devices including skyrmions and spin-torque electronics(1-4). Analogous top…
SIESTA: recent developments and applications
Alberto García, Nick Papior, Arsalan Akhtar +33
A review of the present status, recent enhancements, and applicability of the SIESTA program is presented. Since its debut in the mid-nineties, SIESTA's flexibility, efficiency and…
First-principles study of two-dimensional electron and hole gases at the head-to-head and tail-to-tail 180 domain walls in PbTiO ferroelectric thin films
James Sifuna, Pablo García-Fernández, George S. Manyali +2
We study from first-principles the structural and electronic properties of head-to-head (HH) and tail-to-tail (TT) 180 domain walls in isolated free-standing PbTiO sl…
Comparison of band-fitting and Wannier-based model construction for WSe
James Sifuna, Pablo García-Fernández, George S. Manyali +2
Transition metal dichalcogenide materials are being thoroughly studied due to their novel two-dimensional structure, that is associated with exceptional opti…
Novel mechanisms to enhance the capacitance beyond the classical limits in capacitors with free-electron-like electrodes
Javier Junquera, Pablo García-Fernández, Massimiliano Stengel
The so-called negative electron compressibility refers to the lowering of the chemical potential of a metallic system when the carrier density increases. This effect has often been…
