Exact diagonalization of quantum lattice models on coprocessors
Topi Siro, Ari Harju
We implement the Lanczos algorithm on an Intel Xeon Phi coprocessor and compare its performance to a multi-core Intel Xeon CPU and an NVIDIA graphics processor. The Xeon and the Xe…

Impurities and Landau level mixing in a fractional quantum Hall state in a flatband lattice model
Topi Siro, Mikko Ervasti, Ari Harju
We study the toplogical checkerboard lattice model around the fractional quantum Hall phase using numerical exact diagonalization without Landau level projections.…

Enhancement models of momentum densities of annihilating electron-positron pairs: the many-body picture of natural geminals
Ilja Makkonen, Mikko M. Ervasti, Topi Siro +1
The correlated motion of a positron surrounded by electrons is a fundamental many-body problem. We approach this by modeling the momentum density of annihilating electron-positron…
