Scalar Fields in Cosmology: Inflation, Dark Matter, Dark Energy Louis, Jan "Scalar Fields in Cosmology: Inflation, Dark Matter, Dark Energy" in Particles, Strings and the Early Universe : The Structure of Matter and Space-Time / Haller, Johannes, Grefe, Michael (eds.), Verlag Deutsches Elektronen-Synchrotron : 2018 Hamburg : Verlag Deutsches Elektronen-Synchrotron 341-361 (2018) [10.3204/PUBDB-2018-00782/C6]   During the 12 years of project C6 of the SFB 676 it has achieved a set of significant contributions to our understanding of the dynamics of scalar fields in early universe cosmology and its connection to string theory. In this contribution we describe our results at this interface between theoretical cosmology and fundamental high-energy theory in their impacts on string inflation'~ consequences of multi-field inflation in string theory inspired random potentials', pole inflation, $f(R)$-gravity, and exponential inflationary plateaus', the phenomenological consequences of features before and during inflation', false-vacuum tunneling and its consequences for the initial conditions of inflation', connections between slow-rolling scalar fields and electroweak symmetry breaking due to couplings between the Standard Model (SM) Higgs field and inflation, moduli stabilization and de Sitter (dS) vacua in string theory', as well as the connection of dS vacua to sequestering as a solution to the cosmological constant problem', and on the connection between measurements of ${\rm \Lambda CDM}$ parameters from the CMB as well as local data such as the local $H_0$ determinations, and effects from large-scale structure such as weak gravitational lensing.

A Prototype Phase Shifter for the Undulator Systems at theTESLA X-ray FEL [TESLA-FEL 2000-08] 9 pp. (2000) Five SASE FEL’s and five spontaneous undulator systems are proposed for the FEL lab at TESLA. The SASEsystems are the longest. [...] Restricted: PDF PDF (PDFA); 2018-08-3115:16 [PUBDB-2018-03327] Report Pfüger, J. Conceptual Design of the Gap Separation Drives for the Undulators for the TESLA X-FEL [TESLA FEL 2000-07] 16 pp. (2000) A conceptual design study of the mechanical drive and support systems of the undulator segments for the X-rayFEL has been performed. 281 of these systems will be needed for the undulator systems.

Parameter Evaluation for Microwave Undulator Schemes [ TESLA FEL 2001-08 ] 14 pp. (2001) An undulator can be realized not only by static magnetic fields, but also by an electro-magnetic wave in a waveguide. The major advantage is fast tunability of the RF undulator,whereas on the downside the field strength seems to be limited at levels of 0:2 : : : 0:3T.

F. F. SASE FEL at the TESLA Facility, Phase2 [TESLA-FEL 2002-01 ] 49 pp. (2002) The last description of the TESLA Test Facility FEL has been written in 1995 (TESLA-FEL report 95-03). Since then, many changes have developed compared to the design,partially because the design was incomplete, partly because of gained knowledge over thepast few years. [...] Restricted: PDF PDF (PDFA);
