1 Lecture 1: Introduction and motivation Solid-State Physics IShahid Beheshti University, Tehran, IranFall semester 2011Educational team:Hamed Saberi, Ph.D.Massoud Amiri, M.Sc.Mehdi Zahedi, B.E.E.Lecture 1: Introduction and motivationShahrivar 29, 1390Abstract:The generation of multiqubit entangled states via a single global unitary operation acting on initially decoupled qubits is in general known to be a difficult problem. Therefore, several theoretical and experimental efforts have been made to develop sequential protocols for the generation of paradigmatic entangled multiqubit states. We demonstrate how the matrix-product state formalism provides a flexible structure for such a quantum factory of states. The proposed method relies on a suitable local optimization procedure, yielding an efficient recipe for the realistic and approximate sequential generation of any entangled multiqubit state under experimental restrictions. We give paradigmatic examples that may be of interest for theoretical and experimental developments.

6 Solid-state physics: the advent Solid-state physics studies how the large-scale properties of solid materials result from their atomic-scale properties.The birth of solid-state physics as a separate field with the publication of Fredrick Seitz’s book, Modern Theory of Solids (1940) coalescing parts of many fields such as metallurgy, crystallography, magnetism, and electronic conduction in solids into the new field of solid-state physics.About twenty years later: the advent of the term condensed-matter physics, including solid-state but also liquids and a variety of materials in condensed phase like quantum fluids, liquid crystals, complex systems etc
7 Solid-state/condensed-matter phys.: main features B?A𝑃 𝐴𝐵𝐶𝐷 = 𝑃 𝐴 + 𝑃 𝐵 + 𝑃 𝐶 + 𝑃 𝐷CDNot necessarily!Collective phenomena, interactions, correlationsNovel collective phenomena: High-temperature superconductivity, superfluidity, Anderson localization, Bose-Einstein condensation (BEC), persistent currents, Mott insulators, Kondo effect, Fractional quantum Hall effect (FQHE) etc"More is different!": Emergent simplifying properties at a higher level of complexity: crystal symmetry, thermodynamic limit, the laws of statistics etc
8 Solid-state physics: the significance As the largest branch of condensed-matter physics (CMP), it aims at understanding and explaining macroscopic properties of the materials from interactions among constituent particles.CMP identified as the largest field of contemporary physics: around 1/3 of US physicists belong to condensed-matter category!Over the past 50 years, 22 Nobel prizes in physics went to condensed-matter!Proof by contradiction: cf. budgets toward CMP in developing countires to that of the developed world!
9 Solid-state physics and emerging technologies Semiconductor technlogy: Transistor and integrated circuits technologySuperconductor technologies: SQUID2007's physics Nobel prize for hard disk technologyGraphene (Nobel prize in physics 2010)The "tsunami" of Nanotechnology:phase-coherent contorl of nature at nano-scaleQuantum dots:Artificial atoms
13 Course objectivesIntroduction to basic concepts of solid-state physics either to excite the mind for pursuing a condensed matter career or to give a fair overview of the subject to audience with ambitions towards other disciplines of physicsIllustration of modern examples of technological interest (carbon nanotubes, band structure of graphite and grapheme, quantum Hall effect, transport theory of nanostructures, giant magnetoresistance for hard disk technology along with a pedagogical presentation of the traditional solid-state topicsConsiderable attention to the theory of band structures, semiconducting materials and Fermi surface analysisMuch emphasis on exercises of pedagogical merit as well as research-oriented ones through team work under intensive and regular tutorial sessions

22 Grading/evaluation policy CreditContributionClass activity (relevant and penetrating questions, suggestions, corrections, deep understanding, efforts and dedication towards the course and the subject, etc)20%Exercises= handouts+ solution presentation upon tutorial sessions* (*5% per presentation)20%+20%Midterm examFinal exam∑ 100%
24 RequestPlease send me an with the subject "Solid-State Physics I" and in the body a message containing info of the following format:Surname, first name:Institute:Field of specialization:Main science interests:e.g.Saberi, HamedPhysics Departement, Shahid Beheshti UniversityCondensed matter theoryMesoscopic Physics, Quantum information
25 Attaendance in tutorial sessions is highly recommended! Besides the 20% presentation credit, complementary course materials (and sometimes some parts of the syllabus) will be covered throughout the tutorial sessions!Please do stick to one tutor for evaluation but feel free to attend whichever sessions you wish
26 Tips to succeed in this course Working hard!To feel free to ask as many questions as possible/neededDiscussing a lot with other course participantsIdentifying local experts (graduate students of condensed matter around etc) for possible questions/discussionsAttending tutorial sessions regularlyProviding regular feedbaks/suggestions to the educational teamAvoiding philiosophiizng physics and learning rather by doing!And most importantly:Reading s and visiting course home-page regularly!
27 Just do it and get it to work! CaveatsPragmatism vs Iranian/Indian understading of sceince especially among students communityNever expect to digest anything upon the first iteration. Don‘t get stuck, rather keep going ahead and always allow multiple iterationsDon't be surprised happening to hear the most commonly used term of science, namely, "I don't know" even from Nobel laureates and try to practice the intellectual courage of using that as much as needed!Obsolete scientific concepts after adoption of Copenhagen doctrine:To understand, to learn, to teach, to read or to study, to waste time on deriving equations of others, to do science only to enjoy it etcJust do it and get it to work!
28 A bit of getting the chest off ... “To be, or not to be, that is the question: … ”!
29 Suggestions/feedbacks always welcome! “Those who never make mistakes make the biggest mistake of all: they never try anything new!”Looking forward to seeing you all in the course!Do you approve by now that: 1+1≠2?
