Correlation Effects and Non-Collinear Magnetism in the Doped Hubbard Model [PDF]

open access: yes, 2015
The ground--state magnetic phase diagram is investigated for the two-- and three--dimensional $t$--$t'$ Hubbard model. We take into account commensurate ferro--, antiferromagnetic, and incommensurate (spiral) magnetic phases, as well as phase separation ...

Bandwidth selection in kernel density estimation: Oracle inequalities and adaptive minimax optimality [PDF]

open access: yes, 2011
We address the problem of density estimation with $\mathbb{L}_s$-loss by selection of kernel estimators. We develop a selection procedure and derive corresponding $\mathbb{L}_s$-risk oracle inequalities. It is shown that the proposed selection rule leads
