Kondo Screening and Indirect Magnetic Exchange through a Conventional Superconductor Studied by the Density-Matrix Renormalization Group

Cassian Plorin, Michael Potthoff

The competition between the Kondo screening and indirect magnetic exchange in systems with two magnetic impurities coupled to a conventional s-wave superconductor gives rise to a n…

Quantum spin spiral ground state of the ferrimagnetic sawtooth chain

Roman Rausch, Matthias Peschke, Cassian Plorin +2

The ferrimagnetic phase of the sawtooth chain with mixed ferromagnetic nearest-neighbour interactions and antiferromagnetic next-nearest-neighbour interactions (within the…

Magnetic properties of a capped kagome molecule with 60 quantum spins

Roman Rausch, Matthias Peschke, Cassian Plorin +1

We compute ground-state properties of the isotropic, antiferromagnetic Heisenberg model on the sodalite cage geometry. This is a 60-spin spherical molecule with 24 vertex-sharing t…

Matrix-product state approach to the generalized nuclear pairing Hamiltonian

Roman Rausch, Cassian Plorin, Matthias Peschke +1

We show that from the point of view of the generalized pairing Hamiltonian, the atomic nucleus is a system with small entanglement and can thus be described efficiently using a 1D…

The antiferromagnetic Heisenberg model on the fullerene geometry

Roman Rausch, Cassian Plorin, Matthias Peschke

We solve the quantum-mechanical antiferromagnetic Heisenberg model with spins positioned on vertices of the truncated icosahedron using the density-matrix renormalization group (DM…
