The Pauli principle and magnetism
Alexander A. Klyachko
According to Heisenberg ferrmagnetism stems from the Pauli magic mediating between Coulomb interaction and electrons' spins. The primary aim of the paper is to turn the magic into…
Rank Reduction for the Local Consistency Problem
Jianxin Chen, Zhengfeng Ji, Alexander Klyachko +2
We address the problem of how simple a solution can be for a given quantum local consistency instance. More specifically, we investigate how small the rank of the global density op…
The Pauli exclusion principle and beyond
Alexander A. Klyachko
The Pauli exclusion principle can be stated as inequality for the electron density matrix . Nowadays it is replaced by skew symmetry of the multi-electron wave fu…
Dynamic symmetry approach to entanglement
Alexander Klyachko
In this lectures I explain a connection between geometric invariant theory and entanglement, and give a number of examples how this approach works.
The Pauli principle revisited
M. Altunbulak, A. Klyachko
By the Pauli exclusion principle no quantum state can be occupied by more than one electron. One can put it as a constraint on the electron density matrix that bounds its eigenvalu…
A simple test for hidden variables in spin-1 system
Alexander A. Klyachko, M. Ali Can, Sinem Binicioğlu +1
We resolve an old problem about the existence of hidden parameters in a three-dimensional quantum system by constructing an appropriate Bell's type inequality. This reveals a noncl…
