In Search Of The K P

I ?rst heard of k·p in a course on semiconductor physics taught by my thesis adviser William Paul at Harvard in the fall of 1956. He presented the k·p Hamiltonian as a semiempirical theoretical tool which had become rather useful for the interpre- tion of the cyclotron resonance experiments, as reported by Dresselhaus, Kip and Kittel. This perturbation technique had already been succinctly discussed by Sho- ley in a now almost forgotten 1950 Physical Review publication. In 1958 Harvey Brooks, who had returned to Harvard as Dean of the Division of Engineering and Applied Physics in which I was enrolled, gave a lecture on the capabilities of the k·p technique to predict and ?t non-parabolicities of band extrema in semiconductors. He had just visited the General Electric Labs in Schenectady and had discussed with Evan Kane the latter’s recent work on the non-parabolicity of band extrema in semiconductors, in particular InSb. I was very impressed by Dean Brooks’s talk as an application of quantum mechanics to current real world problems. During my thesis work I had performed a number of optical measurements which were asking for theoretical interpretation, among them the dependence of effective masses of semiconductors on temperature and carrier concentration. Although my theoretical ability was rather limited, with the help of Paul and Brooks I was able to realize the capabilities of the k·p method for interpreting my data in a simple way.

THE SUNDAY TIMES BESTSELLER 'Outrageous, audacious, jaw-dropping' SUNDAY TIMES 'An essential read' DAILY MAIL 'Utterly captivating' DAILY TELEGRAPH 'Hugely entertaining' GUARDIAN The fascinating life story of professional cricketer Kevin Pietersen, MBE, from his childhood in South Africa to his experiences as one of the leading lights in the world of international cricket. Kevin was dropped from the England squad in February 2014, seemingly calling time on an international career that began nearly ten years earlier. The decision puzzled many observers - although the England team had failed miserably in the Ashes tour of 2013-14, Kevin was the tourists' leading run scorer across the series, and he remains the country's highest run scorer of all time across all formats of the game. Kevin reveals all in his autobiography, telling the stories behind the many other highs and lows of his incredible career. Giving readers the full story of his life, from his childhood in South Africa to his experiences as one of the leading lights in the world of international cricket, KP is an autobiography that entertains and fascinates readers in equal measure.

Sindhi nationalism is one of the oldest yet least studied cases of identity politics in Pakistan. Ethnic discontent appeared in Sindh in opposition to the rule of the Bombay presidency; to the onslaught of Punjabi settlers in the wake of canal irrigation; and, most decisively, to the arrival of millions of Muhajirs (Urdu-speaking migrants) after Partition. Under Zulfikar Ali Bhutto, Benazir Bhutto and Asif Zardari, the Pakistan People's Party has upheld the Sindhi nationalist cause, even while playing the game of federalist politics. On the other side for half a century have been hardcore Sindhi nationalist groups, led by Marxists, provincial autonomists, landlord pirs and liberal intelligentsia in pursuit of ethnic outbidding. This book narrates the story of the Bhutto dynasty, the Muhajir factor, nationalist ideologues, factional feuds amongst landed elites, and the role of violence as a maker and shaper of Sindhi nationalism. Moreover, it examines the role of the PPP as an ethnic entrepreneur through an analysis of its politics within the electoral arena and beyond. Bringing together extensive fieldwork and comparative studies of ethno-nationalism, both within and outside Pakistan, Asma Faiz uncovers the fascinating world of Sindhi nationalism.

This book is designed for the reader who wants to get a general view of the terminology of General Topology with minimal time and effort.

The book provides an extensive analysis of extremism, extremist narratives and counter-narratives and their role in consolidating exclusive religious, cultural and social identities in Pakistan. Focusing on the construction and institutionalization of extremist tendencies, the book studies the process of the adoption of the narrow interpretation of religion and society, which subsequently was equated with national identity. It looks at the efforts of counter-extremism narratives, which tend to focus on violent extremism while overlooking non-violent manifestations. The author highlights that the main issue with counter-narratives is the difficulty in presenting extremism and its narratives as a threat since they have been normalized with the state being part of facilitating and building them. A valuable and much-required contribution to the existing literature on extremism and narrative building in Pakistan, this book would help students, academics and policymakers in identifying the limitations of counter-narratives in Pakistan, while providing them with a detailed overview of extremism and extremist narratives. It will also be of interest to researchers studying Security Studies and Asian Politics, especially in the context of South Asia.

The Volume on Advances in Steiner Trees is divided into two sections. The first section of the book includes papers on the general geometric Steiner tree problem in the plane and higher dimensions. The second section of the book includes papers on the Steiner problem on graphs. The general geometric Steiner tree problem assumes that you have a given set of points in some d-dimensional space and you wish to connect the given points with the shortest network possible. The given set ofpoints are 3 Figure 1: Euclidean Steiner Problem in E usually referred to as terminals and the set ofpoints that may be added to reduce the overall length of the network are referred to as Steiner points. What makes the problem difficult is that we do not know a priori the location and cardinality ofthe number ofSteiner points. Thus)the problem on the Euclidean metric is not known to be in NP and has not been shown to be NP-Complete. It is thus a very difficult NP-Hard problem.
