2. 1. Raman Scattering Studies of High-Tc Superconductors

   Author : Mikael Käll; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; superconducting gap; phonons; Raman scattering; high-Tc superconductivity;

   Abstract : This thesis describes Raman scattering investigations of cuprate high-Tc superconductors. The objective is to gain further knowledge on the physical properties that are relevant for the appearance of high-Tc superconductivity. READ MORE

5. 3. Theoretical Studies of Raman Scattering

   Author : Abdelsalam Mohammed; Hans Ågren; Luciano Frediani; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; Teoretisk kemi;

   Abstract : Different theoretical approaches have been presented in this thesis to study the Raman scattering effect. The first one is response theory applied up to third order of polarization, where the determination of α, β and γ is used to calculate linear Raman scattering (resonance Raman scattering (RRS) and normal Raman scattering (NRS)), hyper Raman scattering (HRS) and coherent anti-Stokes Raman scattering (CARS), respectively.

6. 4. Direct imaging of Stimulated Raman scattering : 3D spatial control and spatial generation

   Author : Ronja Eriksson; Kerstin Ramser; Mikael Sjödahl; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Experimental Mechanics; Experimentell mekanik;

   Abstract : Stimulated Raman scattering (SRS) is a powerful imaging technique that has become popular during the last decades for its ability to image species specific in a sample with high accuracy. The purpose of this thesis is twofold. Firstly, to demonstrate 3D spatial control of where in the sample SRS is generated. READ MORE

7. 5. Spontaneous and stimulated X-ray Raman scattering

   Author : Yu-Ping Sun; Faris Gel'mukhanov; Vincenzo Carravetta; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resonant X-ray scattering; resonant Auger scattering; rotational Doppler broadening; XFEL pulse; Atomic and molecular physics; Atom- och molekylfysik; Spectroscopy; Spektroskopi;

   Abstract : The present thesis is devoted to theoretical studies of resonant X-ray scattering and propagation of strong X-ray pulses. In the first part of the thesis the nuclear dynamics of different molecules is studied using resonant X-ray Raman and resonant Auger scattering techniques. READ MORE
