1. 1. Strong light-matter coupling: from traditional to cavity-free polaritons

   Författare :Adriana Canales Ramos; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mie modes; cavity-free polaritons; Lorentz resonances; Polaritonic states; 2D-atomic crystals; ultrastrong coupling; strong coupling; Fabry-Pérot modes;

   Sammanfattning : Polaritons are formed when light and matter interact strongly. For this to occur, photons and transitions in a material must exchange energy faster than the dissipation rate of the interacting components. Polaritons have shown the ability to change such material properties as photophysics, chemical reaction rates, transport, etc. LÄS MER

3. 2. Strong Light-Matter Coupling: the Road from Conventional to Cavity-Free Polaritons

   Författare :Adriana Canales Ramos; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fabry-Pérot microcavities; self-hybridized polaritons; Mie modes; Strong and ultrastrong coupling; Lorentz resonances; decay rates; cavity-free polaritons; Casimir force; 2D–crystals; plasmons; water droplets.; self-assembled microcavities;

   Sammanfattning : The interaction between light and matter is fundamental in perceiving and understanding the world. The interaction is typically weak, meaning light only perturbs matter without changing its properties. LÄS MER

   Sammanfattning : The first part of this thesis deals with long wavelength (1.2-1.3 um) InGaAs(N)multiple quantum-well (QW) lasers grown on GaAs, with the aim of understandingand improving their threshold and temperature characteristics. The epitaxialmaterial is grown by molecular beam epitaxy (MBE). LÄS MER

5. 4. Frequency comb Brillouin microscopy

   Författare :Felipe Ademir Alemán Hérnandez; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brillouin light scattering; optics; spinwave spectroscopy; phonon spectroscopy; microscopy; Fabry-Perot interferometer; Frequency comb;

   Sammanfattning : Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied in fields as diverse as acoustics, spintronics, geosciences, and biophysics. LÄS MER

7. 5. Transport properties of Bi2Se3 Topological Insulator Nanoribbon-Superconductor hybrid junctions

   Författare :Ananthu Pullukattuthara Surendran; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bismuth selenide; surface states; Topological insulator; ac susceptibility; Josephson junctions; superconductivity; SQUID; andreev bound states;

   Sammanfattning : In recent years, topological superconductivity and Majorana zero-energy modes have attracted vast interest due to their potential for topologically protected quantum information processing. Hybrid devices involving a conventional s-wave superconductor (S) in proximity to a 3D Topological Insulator (TI) are expected to provide a platform for emulating and studying these phenomena. LÄS MER
