Angular momentum blockade in nanoscale high-T_c superconducting grains
Francesco Mancarella, Alexander V. Balatsky, Mats Wallin +1
We discuss the angular momentum blockade in small d-wave superconducting grains in an external field. We find that abrupt changes in angular momentum state of the condensate, angul…
On the -binomial distribution and the Ising model
P. H. Lundow, A. Rosengren
A completely new approach to the Ising model in 1 to 5 dimensions is developed. We employ -binomial coefficients, a generalisation of the binomial coefficients, to describe th…
Isotope effect on superconductivity in Josephson coupled stripes in underdoped cuprates
A. Rosengren, P. H. Lundow, A. V. Balatsky
Inelastic neutron scattering data for YBaCuO as well as for LaSrCuO indicate incommensurate neutron scattering peaks with incommensuration away from the point. $T_c(…
Transition from a two-dimensional superfluid to a one-dimensional Mott insulator
Sara Bergkvist, Robert Saers, Emil Lundh +3
A two-dimensional system of atoms in an anisotropic optical lattice is studied theoretically. If the system is finite in one direction, it is shown to exhibit a transition between…
One-dimensional extended Bose-Hubbard model with a confining potential: a DMRG analysis
Laura Urba, Emil Lundh, Anders Rosengren
The extended Bose-Hubbard model in a quadratic trap potential is studied using a finite-size density-matrix renormalization group method (DMRG). We compute the boson density profil…
Spinful bosons in an optical lattice
Sara Bergkvist, Ian McCulloch, Anders Rosengren
We analyze the behavior of cold spin-1 particles with antiferromagnetic interactions in a one-dimensional optical lattice using density matrix renormalization group calculations. C…
