Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. It only takes a minute to sign up. I was wondering whether or not there are any good resources of the type "Problems and Solutions" on String theory, on Supersymmetry and on advanced Quantum Field theory separately.

Nowadays, there are a lot of excellent Quantum Field Theory textbooks. Textbooks usually contain problems without solutions. So, I feel that the absence of such a book in Quantum Field Theory is a gap in the literature. This was my main motivation for writing this Problem Book. To students: You cannot start to do problems without previous study- ing your lecture notes and textbooks. Try to solve problems without using solutions; they should help you to check your results.

Chapters 2, 3 and 4 deal with the rela- tivistic quantum mechanics with a special emphasis on the Dirac equation. In Chapter 5 we present problems related to the Euler-Lagrange equations and the Noether theorem. In Chapter 10 we consider tree level processes, while the last Chapter deals with renormalization and regularization. There are many colleagues whom I would like to thank for their support and help. I thank them all, but it goes without saying that all the errors that have crept in are my own.

C leave the square of the length of a vector invariant, i. In Problem 1. A dual space can be associated to the vector space in the following way. The components of the dual vector transform like 1.

It seems that you're in Germany. We have a dedicated site for Germany. It deals with the Klein-Gordon and Dirac equations, classical field theory, canonical quantization of scalar, Dirac and electromagnetic fields, the processes in the lowest order of perturbation theory, renormalization and regularization. The solutions are presented in a systematic and complete manner. The new edition is a corrected paperback edition for students.

В качестве штатного ангела-хранителя компьютерных систем АН Б Джабба ходил по отделам, делал замечания, что-то налаживал и тем самым постоянно подтверждал свое кредо, гласившее, что профилактика-лучшее лекарство. Ни один из поднадзорных ему компьютеров АНБ не заразился вирусом, и он был намерен не допустить этого и впредь. Рабочим местом Джаббы была платформа, с которой открывался вид на подземную сверхсекретную базу данных АНБ. Именно здесь вирус мог бы причинить наибольший ущерб, и именно здесь Джабба проводил большую часть времени. Однако в данный момент у него был перерыв и он поглощал пирог с сыром и перцем в круглосуточной столовой АНБ.

Если Стратмор окажется на грани срыва, директор заметит первые симптомы.

 Ну, мы не сумели этого сделать. - А вдруг Танкадо умнее. - Может.  - Сьюзан пожала плечами, демонстрируя равнодушие. - Мы с ним какое-то время переписывались, - как бы невзначай сказал Хейл.

Мотоцикл и такси с грохотом въехали в пустой ангар. Беккер лихорадочно осмотрел его в поисках укрытия, но задняя стена ангара, громадный щит из гофрированного металла, не имела ни дверей, ни окон. Такси было уже совсем рядом, и, бросив взгляд влево, Беккер увидел, что Халохот снова поднимает револьвер.

 - Он надеялся, что отказ представителю самого мощного разведывательного ведомства не слишком большая глупость с его стороны, но партия в сквош начиналась через сорок пять минут, а он дорожил своей репутацией: Дэвид Беккер никогда не опаздывает на партию в сквош… на лекцию - да, возможно, но на сквош -. - Постараюсь быть краткой, - улыбнулась Сьюзан Флетчер.  - Пожалуйста. Через десять минут Беккер уже сидел в буфете АНБ, жуя сдобную булку и запивая ее клюквенным соком, в обществе очаровательной руководительницы Отделения криптографии АНБ. Ему сразу же стало ясно, что высокое положение в тридцать восемь лет в АНБ нельзя получить за красивые глаза: Сьюзан Флетчер оказалась одной из умнейших женщин, каких ему только доводилось встречать. Обсуждая шифры и ключи к ним, он поймал себя на мысли, что изо всех сил пытается соответствовать ее уровню, - для него это ощущение было новым и оттого волнующим. Час спустя, когда Беккер уже окончательно опоздал на свой матч, а Сьюзан откровенно проигнорировала трехстраничное послание на интеркоме, оба вдруг расхохотались.

Он подбежал к кассе. - El vuelo a los Estados Unidos. Стоявшая за стойкой симпатичная андалузка посмотрела на него и ответила с извиняющейся улыбкой: - Acaba de salir. Вы на чуть-чуть опоздали.  - Ее слова словно повисли в воздухе.
