MAAPO:an innovative membrane algorithm based on artificial protozoa optimizer for multilevel threshold image segmentation
Xiaopeng Wang, Vaclav Snasel, Seyedali Mirjalili +1
This paper proposes a novel membrane algorithm based on artificial protozoa optimizer (MAAPO) for global optimization problems. The artificial protozoa optimizer (APO) is adopted a…
Optimization Landscape Geometry in VQE for Frustrated Quantum Spin Models
Vojtěch Novák, Ivan Zelinka, Swagatam Das +1
We benchmark eight classical optimizers for exact-statevector VQE calculations on a controlled hierarchy of frustrated spin models, ranging from a diagonal Ising glass to transvers…
The bixbyite framework as a platform for frustrated noncollinear magnetism: resolving the magnetic ground state of -FeO
Chenjun Tang, Ondřej Malina, Jiři Tuček +3
Magnetic behavior across FeO polymorphs varies widely despite identical chemistry, highlighting crystal architecture as a key determinant of exchange topology, magnetic ani…
Sketching a Space of Brain States
Maria Mannone, Patrizia Ribino, Peppino Fazio +1
Brain functional connectivity alterations, that is, pathological changes in the signal exchange between areas of the brain, occur in several neurological diseases, including neurod…
Cubic magneto-optic Kerr effect in Co(111) thin films
Maik Gaerner, Robin Silber, Malte Schäffer +4
The magneto-optic Kerr effect (MOKE) is often applied as a tool for the magnetic characterization of thin films. Here, the change in polarization upon reflection from the magnetize…
Cubic-in-magnetization contributions to the magneto-optic Kerr effect investigated for Ni(001) and Ni(111) thin films
Robin Silber, Maik Gaerner, Kamil Postava +2
*The abstract of this article is too long to be included in the arXiv metadata; please see the paper for the full abstract.* ...In this paper, we introduce the detailed theory of c…
