Rational Control of Magnonic and Electronic Band Splittings
Subhadeep Bandyopadhyay, Anoop Raj, Philippe Ghosez +2
We provide a theoretical demonstration of controllable non-relativistic spin splitting in both electronic and magnonic bands via targeted structural distortions tied to specific ph…
Switchable Skyrmion-Antiskyrmion Tubes in Rhombohedral BaTiO and Related Materials
Fernando Gómez-Ortiz, Louis Bastogne, Sriram Anand +3
Skyrmions are stable topological textures that have garnered substantial attention within the ferroelectric community for their exotic functional properties. While previous studies…
Assessing the nature of nanoscale ferroelectric domain walls in lead titanate multilayers
Edoardo Zatterin, Petr Ondrejkovic, Louis Bastogne +12
The observation of unexpected polarisation textures such as vortices, skyrmions and merons in various oxide heterostructures has challenged the widely accepted picture of ferroelec…
Lattice-distortion couplings in antiferroelectric perovskite and comparison with
Huazhang Zhang, Konstantin Shapovalov, Safari Amisi +1
Lead-free antiferroelectric perovskite is nowadays attracting extensive research interests due to its promising applications in energy storage. Although great progres…
Dynamical manipulation of polar topologies from acoustic phonon pumping
Louis Bastogne, Fernando Gómez-Ortiz, Sriram Anand +1
Since the recent discovery of polar topologies, a recurrent question has been in the way to remotely tune them. Many efforts have focused on the pumping of polar optical phonons fr…
Structurally triggered orbital and charge orderings in TlMnO and related compounds
Subhadeep Bandyopadhyay, Philippe Ghosez
Rare earth perovskites (MO), with electronic occupation of the M states, display different types of metal-insulator transition. For manganites (M=Mn)…
Finite-temperature properties of antiferroelectric perovskite from deep learning interatomic potential
Huazhang Zhang, Hao-Cheng Thong, Louis Bastogne +3
The prototypical antiferroelectric perovskite (PZO) has garnered considerable attentions in recent years due to its significance in technological applications and fun…
Engineering Symmetry Breaking Interfaces by Nanoscale Structural-Energetics in Orthorhombic Perovskite Thin Films
Duncan T. L. Alexander, Hugo Meley, Michael Marcus Schmitt +4
The atomic configuration of phases and their interfaces is fundamental to materials design and engineering. Here, we unveil a transition metal oxide interface, whose formation is d…
