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

    Author : Mikael Käll; Chalmers University of Technology; []
    Keywords : 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

  3. 3. Spontaneous and stimulated X-ray Raman scattering

    Author : Yu-Ping Sun; Faris Gel'mukhanov; Vincenzo Carravetta; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 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

  4. 4. Theoretical Studies of Raman Scattering

    Author : Abdelsalam Mohammed; Hans Ågren; Luciano Frediani; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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.

  5. 5. Multimodal applications in medical technology that utilize Raman spectroscopy

    Author : Joel Wahl; Kerstin Ramser; Mikael Sjödahl; Thomas Bocklitz; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Raman spectroscopy; Preprocessing; Pulmonary arterial smooth muscle cells; Brain tumors; Experimentell mekanik; Experimental Mechanics;

    Abstract : Biology can often be explained by structures and interactions between molecules. It is therefore of importance for medical sciences that the chemical reactions and molecular compositions of biological samples can be measured. The purpose of this thesis is twofold. READ MORE
