Spin Dynamics in Two-Dimensional Quantum Materials: A Theoretical Study

Spin Dynamics in Two-Dimensional Quantum Materials: A Theoretical Study by Marc Vila Tusell
English | EPUB | 2022 | 169 Pages | ISBN : 3030861139 | 28.1 MB

This thesis focuses on the exploration of nontrivial spin dynamics in graphene-based devices and topological materials, using realistic theoretical models and state-of-the-art quantum transport methodologies. The main outcomes of this work are: (i) the analysis of the crossover from diffusive to ballistic spin transport regimes in ultraclean graphene nonlocal devices, and (ii) investigation of spin transport and spin dynamics phenomena (such as the (quantum) spin Hall effect) in novel topological materials, such as monolayer Weyl semimetals WeTe2 and MoTe2.

Discovery of Co-existing Non-collinear Spin Textures in D2d Heusler Compounds by Jagannath Jena
English | PDF | 2022 | 147 Pages | ISBN : 3031039092 | 6.8 MB

Non-collinear spin textures have attracted significant attention due to their topological nature, emergent electromagnetic properties, and potential spintronic and magnonic device applications. This book explores the physical properties of distinct spin textures in D2d compounds. The main goals of the work are (a) discovering new spin textures in D2d Heusler compounds and studying their detailed properties to enrich the field of non-collinear magnetism (b) optimizing the nano-track geometry and generating isolated and single chains of nano-objects that will establish new hallmarks for technological applications © studying the stability of spin textures with magnetic fields and temperatures and finding a way to observe the striking behavior of spin textures near the specimen edges.

Quantized Phenomena of Transport and Magneto-Optics in Magnetic Topological Insulator Heterostructures

Quantized Phenomena of Transport and Magneto-Optics in Magnetic Topological Insulator Heterostructures by Masataka Mogi
English | EPUB | 2022 | 120 Pages | ISBN : 9811921369 | 31.8 MB

This book presents experimental studies on emergent transport and magneto-optical properties in three-dimensional topological insulators with two-dimensional Dirac fermions on their surfaces. Designing magnetic heterostructures utilizing a cutting-edge growth technique (molecular beam epitaxy) stabilizes and manifests new quantization phenomena, as confirmed by low-temperature electrical transport and time-domain terahertz magneto-optical measurements.

Designing Topological Phase of Bismuth Halides and Controlling Rashba Effect in Films Studied by ARPES

Designing Topological Phase of Bismuth Halides and Controlling Rashba Effect in Films Studied by ARPES by Ryo Noguchi
English | PDF,EPUB | 2022 | 139 Pages | ISBN : 9811918732 | 47.2 MB

This book presents the observation and the control of spin-polarized electrons in Rashba thin films and topological insulators, including the first observations of a weak topological insulator (WTI) and a higher-order topological insulator (HOTI) in bismuth halides. It begins with a general review of electronic structures at the solid surface and mentions that an electron spin at a surface is polarized due to the Rashba effect or topological insulator states with strong spin-orbit coupling.
