Book excerpt: Here, a variety of heavy fermion superconductors, such as UCoGe, UGe2, and URhGe exhibit a striking coexistence of bulk ferromagnetism and superconductivity. In the first two materials, the magnetic moment decreases with pressure, and vanishes at a ferromagnetic quantum critical point (qcp). Remarkably, the superconductivity in UCoGe varies smoothly with pressure across the qcp and exists in both the ferromagnetic and paramagnetic regimes. We argue that in UCoGe, spin-orbit interactions stabilize a time-reversal invariant odd-parity superconductor in the high pressure paramagnetic regime. Based on a simple phenomenological model, we predict that the transition from the paramagnetic normal state to the phase where superconductivity and ferromagnetism coexist is a first-order transition.

Book Synopsis Emergent Transport Properties of Magnetic Topological Insulator Heterostructures by : Kenji Yasuda
Download or read book Emergent Transport Properties of Magnetic Topological Insulator Heterostructures written by Kenji Yasuda and published by Springer Nature. This book was released on 2020-09-07 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reveals unique transport phenomena and functionalities in topological insulators coupled with magnetism and superconductivity. Topological insulators are a recently discovered class of materials that possess a spin-momentum-locked surface state. Their exotic spin texture makes them an exciting platform for investigating emergent phenomena, especially when coupled with magnetism or superconductivity. Focusing on the strong correlation between electricity and magnetism in magnetic topological insulators, the author presents original findings on current-direction-dependent nonreciprocal resistance, current-induced magnetization reversal and chiral edge conduction at the domain wall. In addition, he demonstrates how the coupling between superconductivity and topological surface state leads to substantial nonreciprocal resistance. The author also elucidates the origins of these phenomena and deepens readers’ understanding of the topologically nontrivial electronic state. The book includes several works which are published in top journals and were selected for the President’s Award by the University of Tokyo and for the Ikushi Prize, awarded to distinguished Ph.D. students in Japan.

This book was released on 2010-11-10 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: For emerging energy saving technologies superconducting materials with superior performance are needed. Such materials can be developed by manipulating the "elementary building blocks" through nanostructuring. For superconductivity the "elementary blocks" are Cooper pair and fluxon (vortex). This book presents new ways how to modify superconductivity and vortex matter through nanostructuring and the use of nanoscale magnetic templates. The basic nano-effects, vortex and vortex-antivortex patterns, vortex dynamics, Josephson phenomena, critical currents, and interplay between superconductivity and ferromagnetism at the nanoscale are discussed. Potential applications of nanostructured superconductors are also presented in the book.

Book Synopsis Superconductivity and Topological Properties in a Topological Semimetal by : K A M Hasan Siddiquee
Download or read book Superconductivity and Topological Properties in a Topological Semimetal written by K A M Hasan Siddiquee and published by . This book was released on 2021 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Topological superconductors (TSCs) in which superconductivity and topological properties are combined are characterized by topologically protected gapless states in the superconducting gaps. Realized in the gapless states of TSCs, Majorana fermions, which are particles and their own antiparticles, have crucial importance in quantum computation and spintronic device applications because of the exotic nature. Despite extensive study for the confirmation of TSCs, the observation of Majorana fermions in bulk superconductors has not been settled yet. Recently, the binary stannide semimetal CaSn3 with a cubic structure has been proposed to be a promising candidate for realizing topological superconductivity. In this dissertation, to clarify whether CaSn3 is a TSC or not, we investigated the superconducting and normal states of CaSn3, based on two criteria proposed by Fu and Berg. In a detailed study of the superconducting state of CaSn3, we find that the anisotropy of the upper critical field shows two-fold symmetry about a C4 axis which can be ascribed to an unconventional pairing state associated with nematic superconductivity. Besides the anisotropy, the temperature dependence of upper critical fields strongly deviates from that of the conventional depairing field described by Werthamer-Helfand-Hohenberg theory, consistent with odd-parity pairing. The possible odd-parity nematic superconducting state in CaSn3, together with a fully-gapped state suggested by Muon spin rotation measurements, meets one of the proposed prerequisites for topological superconductivity. We also present a detailed study of de Haas van Alphen quantum oscillations in a single crystal of CaSn3 with torque magnetometry. In conjunction with density functional theory-based calculations, the observed quantum oscillation frequencies indicate that the Fermi surfaces of CaSn3 enclose an odd number of time-reversal-invariant momenta, satisfying one of the other proposed criteria to realize topological superconductivity. Our findings will provide a new insight to identify topological superconductivity in quantum materials.

This book was released on 2016 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Topological superconductors with and without time-reversal symmetry are new phases of matters which host Majorana zero modes at their ends. The possibility of realizing such phases in various kinds of materials that are experimentally accessible, in addition to their unique signatures in simple transport measurements, has brought significant amount of attention from both theorists and experimentalists in condensed matter physics. In this thesis, we extend the previous studies on the realization of topological superconductors and try to answer some of the open questions regarding their transport signatures.
