Tannaka-Krein duality for compact quantum homogeneous spaces. II. Classification of quantum homogeneous spaces for quantum SU(2)
Kenny De Commer, Makoto Yamashita
We apply the Tannaka-Krein duality theory for quantum homogeneous spaces, developed in the first part of this series of papers, to the case of the quantum SU(2) groups. We obtain a…
Tannaka-Krein duality for compact quantum homogeneous spaces. I. General theory
Kenny De Commer, Makoto Yamashita
An ergodic action of a compact quantum group G on an operator algebra A can be interpreted as a quantum homogeneous space for G. Such an action gives rise to the category of finite…
The second-order reduced density matrix method and the two-dimensional Hubbard model
James S. M. Anderson, Maho Nakata, Ryo Igarashi +2
The second-order reduced density matrix method (the RDM method) has performed well in determining energies and properties of atomic and molecular systems, achieving coupled-cluster…
Monodromy of the Gauss-Manin connection for deformation by group cocycles
Makoto Yamashita
We consider the 2-cocycle deformation of algebras graded by discrete groups. The action of the Maurer-Cartan form on cyclic cohomology is shown to be cohomologous to the cup produc…
Mott Transition and Spin Structures of Spin-1 Bosons in Two-Dimensional Optical Lattice at Unit Filling
Yuta Toga, Hiroki Tsuchiura, Makoto Yamashita +2
We study the ground state properties of spin-1 bosons in a two-dimensional optical lattice, by applying a variational Monte Carlo method to the S=1 Bose-Hubbard model on a square l…
High-fidelity cluster state generation for ultracold atoms in an optical lattice
Kensuke Inaba, Yuuki Tokunaga, Kiyoshi Tamaki +2
We propose a method for generating high-fidelity multipartite spin-entanglement of ultracold atoms in an optical lattice in a short operation time with a scalable manner, which is…
