Book excerpt: NOUS AVONS ETUDIE TROIS SYSTEMES A ELECTRONS LOURDS, CECU 2SI 2, CEPD 2SI 2 ET UGE 2, PAR DES MESURES DE TRANSPORT, D'OSCILLATIONS QUANTIQUES (CEPD 2SI 2) ET DE DIFFRACTION NEUTRONIQUE (UGE 2). LES EXPERIENCES ONT ETE EFFECTUEES DANS DES CONDITIONS EXTREMES : TRES BASSE TEMPERATURE, CHAMP MAGNETIQUE ELEVE ET PRESSION HYDROSTATIQUE. POUR CECU 2SI 2, NOUS AVONS SUIVI L'EVOLUTION DE LA PHASE A MAGNETIQUE QUI S'EFFONDRE RAPIDEMENT SOUS PRESSION. NOUS AVONS MIS EN EVIDENCE UNE RELATION ENTRE LA PHASE A ET LA PRESENCE D'UN MAXIMUM DANS LA DEPENDANCE EN TEMPERATURE DE H C 2. NOTRE ANALYSE A MONTRE QU'A BASSE PRESSION LE SIGNE DE L'INTEGRALE D'ECHANGE DOIT ETRE NEGATIF. LA SUPRACONDUCTIVITE EST ALORS RENFORCEE PAR UNE AUGMENTATION DE LA SUSCEPTIBILITE PARAMAGNETIQUE COMME DANS L'EFFET JACCARINO-PETER. L'ANISOTROPIE DE LA PENTE INITIALE DE H C 2 ET DONC CELLE DE LA MASSE EFFECTIVE CHANGE SOUS PRESSION. POUR CEPD 2SI 2, L'EFFET DE HAAS-VAN ALPHEN A PRESSION AMBIANTE ET LA RESISTIVITE ELECTRIQUE SOUS PRESSION ONT ETE ETUDIES. CETTE DERNIERE MONTRE UN COMPORTEMENT NON LIQUIDE DE FERMI A PROXIMITE DU POINT CRITIQUE QUANTIQUE ANTIFERROMAGNETIQUE P C27 KBAR. L'ANALYSE DE H C 2 A P C PROUVE QUE L'ETAT SUPRACONDUCTEUR EST BIEN DECRIT PAR LE MODELE DU COUPLAGE FAIBLE EN LIMITE PROPRE, AVEC UNE LIMITE PARAMAGNETIQUE FORTEMENT ANISOTROPE. UGE 2 PRESENTE UNE COEXISTENCE DE FERROMAGNETISME ET DE SUPRACONDUCTIVITE, SE DEVELOPPANT JUSTE EN DESSOUS DU POINT CRITIQUE QUANTIQUE FERROMAGNETIQUE P C16 KBAR. LES MESURES DE RESISTIVITE SOUS PRESSION MONTRENT L'EXISTENCE POSSIBLE D'UNE AUTRE LIGNE DE TRANSITION ET D'UN AUTRE POINT CRITIQUE QUANTIQUE, P X12 KBAR, DANS L'ETAT FERROMAGNETIQUE. LE DIAGRAMME DE PHASE P-T INCLUANT P C ET P X A ETE TRACE, ET UNE RELATION POSSIBLE ENTRE P X ET LE DEVELOPPEMENT DE SUPRACONDUCTIVITE A ETE DISCUTEE. LA DEPENDANCE EN TEMPERATURE DE H C 2 MONTRE UNE VARIETE DE COMPORTEMENTS NOUVEAUX, NE POUVANT PAS ETRE COMPRIS DANS LES MODELES CONVENTIONNELS DE LA SUPRACONDUCTIVITE.

This book was released on 2018-04-26 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large variety of materials prove to be fascinating in solid state and condensed matter physics. New materials create new physics, which is spearheaded by the international experimental expert, Prof Yoshichika Onuki. Among them, the f electrons of rare earth and actinide compounds typically exhibit a variety of characteristic properties, including spin and charge orderings, spin and valence fluctuations, heavy fermions, and anisotropic superconductivity. These are mainly manifestations of better competitive phenomena between the RKKY interaction and the Kondo effect. The present text is written so as to understand these phenomena and the research they prompt. For example, superconductivity was once regarded as one of the more well-understood many-body problems. However, it is, in fact, still an exciting phenomenon in new materials. Additionally, magnetism and superconductivity interplay strongly in heavy fermion superconductors. The understanding of anisotropic superconductivity and magnetism is a challenging problem in solid state and condensed matter physics. This book will tackle all these topics and more.
Download or read book Composite Fermions written by Jainendra K. Jain and published by Cambridge University Press. This book was released on 2007-03-29 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was first published in 2007. When electrons are confined to two dimensions, cooled to near absolute zero temperature, and subjected to a strong magnetic field, they form an exotic new collective state of matter. Investigations into this began with the observations of integral and fractional quantum Hall effects, which are among the most important discoveries in condensed matter physics. The fractional quantum Hall effect and a stream of other unexpected findings are explained by a new class of particles: composite fermions. This textbook is a self-contained, pedagogical introduction to the physics and experimental manifestations of composite fermions. Ideal for graduate students and academic researchers, it contains numerous exercises to reinforce the concepts presented. The topics covered include the integral and fractional quantum Hall effects, the composite-fermion Fermi sea, various kinds of excitations, the role of spin, edge state transport, electron solid, bilayer physics, fractional braiding statistics and fractional local charge.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published as two separate volumes, The Theory of Quantum Liquids is a classic text that attempts to describe the qualitative and unifying aspects of an extremely broad and diversified field. Volume I deals with ‘normal’ Fremi liquids, such as 3He and electrons in metals. Volume II consists of a detailed treatment of Bose condensation and liquid 4He, including the development of a Bose liquid theory and a microscopic basis for the two-fluid model, and the description of the elementary excitations of liquid HeII.

Available in PDF, EPUB and Kindle. Book excerpt: The principal goals of the study were to articulate the scientific rationale and objectives of the field and then to take a long-term strategic view of U.S. nuclear science in the global context for setting future directions for the field. Nuclear Physics: Exploring the Heart of Matter provides a long-term assessment of an outlook for nuclear physics. The first phase of the report articulates the scientific rationale and objectives of the field, while the second phase provides a global context for the field and its long-term priorities and proposes a framework for progress through 2020 and beyond. In the second phase of the study, also developing a framework for progress through 2020 and beyond, the committee carefully considered the balance between universities and government facilities in terms of research and workforce development and the role of international collaborations in leveraging future investments. Nuclear physics today is a diverse field, encompassing research that spans dimensions from a tiny fraction of the volume of the individual particles (neutrons and protons) in the atomic nucleus to the enormous scales of astrophysical objects in the cosmos. Nuclear Physics: Exploring the Heart of Matter explains the research objectives, which include the desire not only to better understand the nature of matter interacting at the nuclear level, but also to describe the state of the universe that existed at the big bang. This report explains how the universe can now be studied in the most advanced colliding-beam accelerators, where strong forces are the dominant interactions, as well as the nature of neutrinos.

This book was released on 1997-04-28 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The behaviour of magnetic impurities in metals has posed problems to challenge the condensed matter theorist over the past 30 years. This book deals with the concepts and techniques which have been developed to meet this challenge, and with their application to the interpretation of experiments. This book will be of interest to condensed matter physicists, particularly those interested in strong correlation problems. The detailed discussions of advanced many-body techniques should make it of interest to theoretical physicists in general.
