Magnetic impurities in a non-magnetic host metal have been actively explored in condensed matter physics in recent last decades. From both fundamental and applied viewpoints these systems are very interesting because they can exhibit strong electronic correlations that give rise to various fascinating phenomena beyond the single particle picture. Up to now our understanding of the underlying processes remains limited due to difficulties involved in measuring these systems on a microscopic scale. With their unique control, scanning tunneling microscopy (STM) and spectroscopy (STS) allow for the first time investigations of phenomena occurring on very small length and energy scales. Here, single magnetic iron and cobalt atoms embedded beneath a metal surface are investigated using these techniques. In particular, the transition from single impurity Kondo physics to two interacting impurities is studied in real space. This thesis contains a comprehensive description of the STM /STS technique, sub-surface impurities, as well as single- and two-impurity Kondo physics - and as such offers a valuable introduction to newcomers to the field.
Now in its second edition, this book is established reading for any practitioner or trainee wishing to develop their own personal style of working. As well as examining contemporary integrative approaches, the authors show how to develop an individual approach to integrating theories and methods from a range of psychotherapies. Offering clear strategies for integration rather than a new therapeutic model, this practical new edition puts added emphasis on the integrative framework, and procedural strategies, extending discussion of the individual practitioner as integrator. It is accessible for the new trainee, whilst posing questions for discussion and reflection for the more experienced practitioner. It integrates recent thinking and research in psychotherapy, human development and neuroscience. It discusses how developments in relational approaches impact on integration in practice. It addresses integration within humanistic, psychodynamic, cognitive behavioural and existential approaches. This book should be on the desk of every trainee studying integrative counselling and psychotherapy, as well as on the shelves of practitioners wanting to develop their own personal frameworks for therapy.
