2. 1. Studies in the Dynamics of Science : Exploring emergence, classification, and interdisciplinarity

   Author : Qi Wang; Ulf Sandström; Martin Meyer; KTH; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; science dynamics; bibliometrics; emerging research topics; interdisciplinary research; journal classification systems; cognitive distance; research policy;

   Abstract : The dynamic nature of science is embodied in the growth of knowledge in magnitude and the transformation of knowledge in structure. More specifically, the growth in magnitude is indicated by a sharp increase in the number of scientific publications in recent decades. READ MORE

4. 2. Quantum acoustics with propagating phonons

   Author : Maria Ekström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; phonon router; unidirectional transducer; phonon; Electromagnetically Induced Transparency; Surface acoustic wave; artificial atom; interdigital transducer; quantum acoustics; qubit; superconducting circuits;

   Abstract : Surface acoustic waves (SAWs) are mechanical vibrations that propagate on the surface of solids while dissipating little power, consequently enabling them to propagate freely over long distances. The speed and wavelength of SAWs are reduced a five order of magnitude compared to when light is used as a carrier at gigahertz frequencies. READ MORE

5. 3. Novel Multi-Scale Modeling Framework for Structure and Transport in Complex Battery Electrolytes

   Author : Rasmus Andersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hierarchical analysis; electrolytes; force field development; molecular dynamics; non-vehicular transport; multi-scale method; Lithium-ion batteries; genetic algorithms;

   Abstract : Affordable high energy rechargeable batteries are crucial for further electrification of the transport sector, which is necessary in order to contribute to limit our CO2 emissions to acceptable levels. While today’s lithium-ion batteries (LIBs) have indeed initiated the electrification of the transportation section successfully, electric vehicles are still expensive and typically have ranges limited to ca.

6. 4. Heat Transport from On-demand Single-Electron Sources

   Author : Nastaran Dashti; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluctuations and noise; thermoelectric devices; energy-selective detector; single-electron source; charge and heat currents;

   Abstract : The controlled injection of quantized charge excitations from single-electron emitters into nanoscopic conductors sets the basis for many important applications ranging from metrology to the emerging field of quantum optics with electrons. Successful implementation of these applications relies not only on achieving control on the precision of the particle emission, but also on the energetic properties of the injected particles.

7. 5. (2,0) Theory and Higher Spin: Twisting, Turning and Spinning Towards Higher Energies

   Author : Hampus Linander; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis investigates an enigmatic six-dimensional quantum theory known as (2,0) theory and a three dimensional conformal theory of higher spin. The former has resisted an explicit construction as a quantum field theory, yet its existence can be inferred from string theory and M-theory where it plays a prominent role. READ MORE
