Coreless Vortices in Rotating Two-Component Quantum Droplets
H. Saarikoski, A. Harju, J. Christensson +3
The rotation of a quantum liquid induces vortices to carry angular momentum. When the system is composed of multiple components that are distinguishable from each other, vortex cor…
On the renormalization of contact interactions for the configuration-interaction method in two dimensions
M. Rontani, G. Eriksson, S. Åberg +1
The configuration interaction (CI) method for calculating the exact eigenstates of a quantum-mechanical few-body system is problematic when applied to particles interacting through…
Magnetic phases of one-dimensional lattices with 2 to 4 fermions per site
J. -P. Nikkarila, M. Koskinen, S. M. Reimann +1
We study the spectral and magnetic properties of one-dimensional lattices filled with 2 to 4 fermions (with spin 1/2) per lattice site. We use a generalized Hubbard model that take…
Universality of Many-Body States in Rotating Bose and Fermi Systems
M. Borgh, M. Koskinen, J. Christensson +2
We propose a universal transformation from a many-boson state to a corresponding many-fermion state in the lowest Landau level approximation of rotating many-body systems, inspired…
