  1. 1. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Simon Wozny; [2020]
    Keywords : topological insulators; edge states; impurities; density of states; Green s function; Floquet; Physics and Astronomy;

    Abstract : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. READ MORE

  2. 2. Enskild firma, aktiebolag eller både och? : skatteskillnader och andra effekter i lantbruksföretag

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Erik Bertilsson; Albin Skure; [2019]
    Keywords : aktiebolag; enskild firma; företagsform; ägarskifte; generationsskifte; mjuka värden; risk; lönsamhet; lantbruksföretag; företagsledning; skatt;

    Abstract : Rationaliseringen av svenskt jordbruk leder till större enheter och högre omsättning, vilket gör valet av företagsform allt viktigare för lantbruksföretagare. Aktiebolag för driften ökar i popularitet hos lantbruksföretagare. READ MORE

  3. 3. Band structures of topological crystalline insulators

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Elisabet Edvardsson; [2018]
    Keywords : Topological insulator; Band structure; Block tridiagonal matrix;

    Abstract : Topological insulators and topological crystalline insulators are materials that have a bulk band structure that is gapped, but that also have toplogically protected non-gapped surface states. This implies that the bulk is insulating, but that the material can conduct electricity on some of its surfaces. READ MORE

  4. 4. The Implications of Earnings Management in Initial Public Offerings - Evidence from the Nordic Stock Markets

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Fanny Oltner Bsenko; Martin Desch; [2018]
    Keywords : Accruals; Earnings management; IPO; Stock performance; Nordic stock market;

    Abstract : This paper evaluates how earnings management in initial public offerings (IPOs) affects long-term stock performance of Nordic firms, focusing on the role of current accruals. We provide evidence that current accruals above the industry standard reliably predict future stock underperformance given a 36-month time period. READ MORE

  5. 5. Variations in Sex Differentiation : The Neurobiology of Gender Dysphoria

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Olivia Rahm; [2017]
    Keywords : gender identity; gender dysphoria; sex; differentiation; gender; transsexuality; neurodevelopment; INAH-3; BSTc;

    Abstract : The aim of this review paper was to investigate variations in sex differentiation, andalso, examine what neurobiological underpinnings there are to gender identity andgender dysphoria. In addition, the most extreme form of gender dysphoria,transsexuality, will be described from a neurobiological perspective but also discussedin terms of the classification from DSM-5. READ MORE
