Any order imaginary time propagation method for solving the Schrodinger equation
Siu A. Chin, S. Janecek, E. Krotscheck
The eigenvalue-function pair of the 3D Schrödinger equation can be efficiently computed by use of high order, imaginary time propagators. Due to the diffusion character of the kine…
Pair Excitations and Vertex Corrections in Fermi Fluids
Helga M. Böhm, Eckhard Krotscheck, Martin Panholzer
Based on an equations--of--motion approach for time--dependent pair correlations in strongly interacting Fermi liquids, we have developed a theory for describing the excitation spe…
Geometric and impurity effects on quantum rings in magnetic fields
M. Aichinger, S. A. Chin, E. Krotscheck +1
We investigate the effects of impurities and changing ring geometry on the energetics of quantum rings under different magnetic field strengths. We show that as the magnetic field…
The effective mass of two--dimensional 3He
J. Boronat, J. Casulleras, V. Grau +2
We use structural information from diffusion Monte Carlo calculations for two--dimensional 3He to calculate the effective mass. Static effective interactions are constructed from t…
Layer- and bulk roton excitations of 4He in porous media
V. Apaja, E. Krotscheck
We examine the energetics of bulk and layer-roton excitations of 4He in various porous medial such as aerogel, Geltech, or Vycor, in order to find out what conclusions can be drawn…
Excitations in confined helium
V. Apaja, E. Krotscheck
We design models for helium in matrices like aerogel, Vycor or Geltech from a manifestly microscopic point of view. For that purpose, we calculate the dynamic structure function of…
