Phase transitions to dipolar clusters and charge density waves in high Tc superconductors
Mikko Saarela, F. V. Kusmartsev
We show that doping of hole charge carriers leads to formation of electric dipolar clusters in cuprates. They are created by many-body interactions between the dopant ion outside a…
Doping induced electronic phase separation and coulomb bubbles in layered superconductors
Mikko Saarela, F V Kusmartsev
We have studied properties of quantum charge fluids interacting with random impurities or heavy polarons using a microscopic Hamiltonian with the full many-body Coulomb interaction…
Elementary Excitations in Bose-Einstein Condensates at Large Scattering Lengths
R. Sarjonen, M. Saarela, F. Mazzanti
We present a theoretical analysis of excitation modes in Bose-Einstein condensates in ultracold alkali-metal gases for large scattering lengths and momenta where corrections to the…
Structure of metastable 2D liquid helium
V. Apaja, M. Saarela
We present diffusion Monte Carlo (DMC) results on a new metastable, superfluid phase above the crystal ground state in two-dimensional 4He at densities > 0.065 1/A^2. The state is…
Single Particle and Fermi Liquid Properties of He-3/--He-4 Mixtures: A Microscopic Analysis
E. Krotscheck, J. Paaso, M. Saarela +2
We calculate microscopically the properties of the dilute He-3 component in a He-3/--He-4 mixture. These depend on both, the dominant interaction between the impurity atom and the…
Quantum sticking, scattering and transmission of 4He atoms from superfluid 4He surfaces
C. E. Campbell, E. Krotscheck, M. Saarela
We develop a microscopic theory of the scattering, transmission, and sticking of 4He atoms impinging on a superfluid 4He slab at near normal incidence, and inelastic neutron scatte…
