Pentagonal 2D Altermagnets: Material Screening and Altermagnetic Tunneling Junction Device Application

open access: yesAdvanced Functional Materials, EarlyView.
From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

Investigation of the Effects of Strain and Electric Field on the Spin‐State Energetics of Co‐Doped BaTiO3 and PbTiO3

open access: yesAdvanced Functional Materials, EarlyView.
Ab initio calculations using the r2SCAN functional show that biaxial strain does not alter the high spin preference of cobalt‐doped BaTiO3 and PbTiO3; a small compressive uniaxial strain however results in an equally favorable low spin state for BaTiO3 and thus bistable magnetism.

Ultrahigh‐resolution (λ/10) Femtosecond Laser Writing of Polymer‐Encapsulated Multicolor Perovskite Patterns Beyond the Diffraction Limit

open access: yesAdvanced Functional Materials, EarlyView.
Fabrication of in situ polymer‐encapsulated stable perovskite patterns of arbitrary shapes and pixel arrays with a resolution of 80 nm is reported by the femtosecond (fs) laser (800 nm) super‐resolution writing technique. The two‐photon absorption‐induced laser ablation is attributed to the achieved feature sizes as small as λ/10.

The quantum information cocoon

Nature Photonics, 2008
Polarization is a convenient way to encode quantum information for cryptography, remote transfer and optical quantum computing, but sharing entanglement is problematic over a noisy link. Hiding in an isolated corner of the state space can make a big difference.
