Negative Full Counting Statistics Arise from Interference Effects

The Keldysh-ordered full counting statistics is a quasiprobability distribution describing the fluctuations of a time-integrated quantum observable. While it is well known that this distribution can fail to be positive, the interpretation and origin of this negativity has been somewhat unclear. Here, we show how the full counting statistics can be tied to trajectories through Hilbert space, and ho

Quantum heat engines based on electronic Mach-Zehnder interferometers

We theoretically investigate the thermoelectric properties of heat engines based on Mach-Zehnder interferometers. The energy dependence of the transmission amplitudes in such setups arises from a difference in the interferometer arm lengths. Any thermoelectric response is thus of purely quantum-mechanical origin. In addition to an experimentally established three-terminal setup, we also consider a

Physical Implementations of Quantum Absorption Refrigerators

Absorption refrigerators are autonomous thermal machines that harness the spontaneous flow of heat from a hot bath into the environment in order to perform cooling. Here we discuss quantum realizations of absorption refrigerators in two different settings: namely, cavity and circuit quantum electrodynamics. We first provide a unified description of these machines in terms of the concept of virtual

Higgs-boson-plus-photon production at the CERN Large Hadron Collider : A clean probe of the b-quark parton densities

Higgs boson production in association with a high pT photon at the CERN Large Hadron Collider is analyzed, in the framework of the MSSM model, for the heavier neutral Higgs bosons. The request of an additional photon in the exclusive Higgs boson final state selects b-quark pairs among the possible initial partonic states, since gluon-gluon initial states are not allowed by C-parity conservation. H

Odderon-Pomeron interference

We show that the asymmetry in the fractional energy of charm versus anticharm jets produced in high energy diffractive photoproduction is sensitive to the interference of the Odderon (C=-) and Pomeron (C=+) exchange amplitudes in QCD. We predict the dynamical shape of the asymmetry in a simple model and estimate its magnitude to be of the order 15% using an Odderon coupling to the proton which sat

Where and when the earliest coccolithophores?

New calcareous nannofossil analyses from the Northern Calcareous Alps of Austria are herein used to update and improve the state of knowledge about the oldest occurrence of coccolithophores reported in the literature. Previously reported Norian occurrences of coccoliths were based on an obsolete Triassic chronostratigraphy, in which the Rhaetian stage was subsumed into the Norian ('Sevatian 2'). T

The city, the church, and the 1960s : On secularization theory and the Swedish translation of Harvey Cox’s The Secular City

In 1994, sociologist of religion José Casanova wrote in the introduction to his influential book Public Religions in the Modern World that a paradigm shift had occurred in his field. His colleagues had abandoned an earlier paradigm “with the same uncritical haste with which they previously embraced it.” 1 What he had in mind was the theory of secularisation: that is, the notion that with modernisa

Institutions, Inequality and Societal Transformations

Institutioner har betydelse för ekonomisk utveckling. Denna avhandling består av tre fristående artiklar som bidrar till olika grenar inom institutionell ekonomi.I den första artikeln undersöks kortsiktiga förändringar av könsnormer. Artikeln tar tillvara på senare tids utveckling av maskininlärningsalgoritmer för att studera normförändringar i svenska tweets. Mer specifikt så tränas en LSTM neuraInstitutions matter for economic development. This thesis consists of three self-contained articles which provide different contributions to institutional economics.The first article studies short-run changes in gender norms. It takes advantage of recent developments in machine learning algorithms to study changes in norms in Swedish tweets. More specifically, gender norms are defined in a compreh

The Long Harm of Childhood: Childhood Exposure to Mortality and Subsequent Risk of Adult Mortality in Utah and The Netherlands

How do early-life conditions affect adult mortality? Research has yielded mixed evidence about the influence of infant and child mortality in birth cohorts on adult health and mortality. Studies rarely consider the specific role of mortality within the family. We estimated how individuals’ exposure to mortality as a child is related to their adult mortality risk between ages 18 and 85 in two histo

Glycosaminoglycans: a link between development and regeneration in the lung : a link between development and regeneration in the lung

What can we learn from embryogenesis to increase our understanding of how regeneration of damaged adult lung tissue could be induced in serious lung diseases such as chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF) and asthma? The local tissue niche determines events in both embryogenesis and repair of the adult lung. Important constituents of the niche are extrace

Recombinant dermatan sulfate is a potent activator of heparin cofactor II-dependent inhibition of thrombin

The glycosaminoglycan dermatan sulfate (DS) is a well-known activator of heparin cofactor II-dependent inactivation of thrombin. In contrast to heparin, dermatan sulfate has never been prepared recombinantly from material of non-animal origin. Here we report on the enzymatic synthesis of structurally well-defined DS with high anticoagulant activity. Using a microbial K4 polysaccharide and the reco
