The book is based on the lectures delivered at the XCIII Session of the ´Ecole de Physique des Houches, held in August, 2009. The aim of the event was to familiarize the new generation of Ph.D. students and postdoctoral Fellows with the principles and methods of modern lattice field theory, which Is set to resolve fundamental, non-perturbative questions about QCD without uncontrolled approximations. The emphasis of the book is on the theoretical developments that have shaped the field in the last two decades and that have turned lattice gauge theory into a robust approach to the determination of low energy hadronic quantities and of fundamental parameters of the Standard Model. By way of introduction, the courses of the school began by covering lattice theory basics (P. Hernández), lattice renormalization and improvement (P. Weisz and A. Vladikas) and the many faces of chirality (D.B. Kaplan). A later course introduced QCD at finite temperature and density (O. Philipsen). A broad view of lattice computation from the basics to recent developments was offered in the corresponding course (M. Lüscher). The students learned the basics of lattice computation in a hands-on tutorial (S. Schaefer)---a first at Les Houches, Extrapolations to physical quark masses and a framework for the parameterization of the low-energy physics by means of effective coupling constants has been covered in the course on chiral perturbation theory (M. Golterman). A course in heavy-quark effective theories (R. Sommer), an essential tool for performing the relevant lattice calculations, covered HQET from its basics to recent advances. A number of shorter courses rounded out the school and broadened its purview. These included recent applications to flavour physics (L. Lellouch) the nucleon--nucleon interation (S. Aoki) and a course on physics beyond the Standard Model (T. Appelquist and E.T. Neil).Less

This chapter reviews the basic building blocks of the regularization of Quantum Field Theories (QFT) on a space-time lattice. It assumes some familiarity with QFT in the continuum. In an introductory section, the path integral formulation is reviewed, focusing on important aspects such as the transfer matrix, the relation of correlation functions and physical observables, the perturbative expansion, and the key issue of renormalization and the Wilsonian renormalization group. It then considers in detail the lattice formulation of scalar, fermion and gauge field theories, paying careful attention to their physical interpretation, and the continuum limit. The difficulty of discretizing chiral fermions is discussed in detail, and various fermion discretizations are described. The strong coupling expansion is introduced in the context of lattice Yang-Mills theory and the criteria for confinement and for the presence of a mass gap are presented. It concludes with a description of Wilson's formulation of lattice QCD and a brief overview of its applications.Less

This chapter examines the epistemological-ontological-ethical implications of temporal dis/junction by reading insights from Quantum Field Theory and Kyoko Hayashi’s account of the destruction wrought by the Nagasaki bombing through one another. The diffraction of time at the core of quantum field theory troubles the scalar distinction between the world of subatomic particles and that of colonialism, war, nuclear physics research, and environmental destruction; all of which entangle the effects of nuclear warfare throughout the present time, troubling the binaries between micro and macro, nature and culture, nonhuman and human. The chapter thus attempts to think through what possibilities remain open for an embodied re-membering of the past which, against the colonialist practices of erasure and avoidance and the related desire to set time aright, calls for thinking a certain undoing of time; a work of mourning more accountable to, and doing justice to, the victims of ecological destruction and of racist, colonialist, and nationalist violence, human and otherwise—those victims who are no longer there, and those yet to come.Less
