An iterative method using boundary distance for box-constrained nonlinear semidefinite programs
Akihiko Komatsu, Makoto Yamashita
We propose an iterative method for nonlinear semidefinite programs with box constraints. The search direction in the proposed method utilizes the distance from the current point to…
Density Modulations Associated with the Dynamical Instability in the Bose-Hubbard Model
Rui Asaoka, Hiroki Tsuchiura, Makoto Yamashita +1
A superfluid flow beyond a critical momentum in an optical lattice decays drastically by the interplay between nonlinearity due to the interparticle interactions in Bose-Einstein c…
Flat-band ferromagnetism in the multilayer Lieb optical lattice
Kazuto Noda, Kensuke Inaba, Makoto Yamashita
We theoretically study magnetic properties of two-component cold fermions in half-filled multilayer Lieb optical lattices, i.e., two, three, and several layers, using the dynamical…
Classification of non-Kac compact quantum groups of SU(n) type
Sergey Neshveyev, Makoto Yamashita
We classify up to isomorphism all non-Kac compact quantum groups with the same fusion rules and dimension function as . For this we first prove, using categorical Poisson bo…
Poisson boundaries of monoidal categories
Sergey Neshveyev, Makoto Yamashita
Given a rigid C*-tensor category C with simple unit and a probability measure on the set of isomorphism classes of its simple objects, we define the Poisson boundary of …
