We propose new measures that distinguish and classify entangled states. The measures are
algebraic invariants of linear maps associated with the states. Considering qubits as well as higher spin syst...
Supersymmetric Extension of Non-Hermitian su(2) Hamiltonian and Supercoherent States
pseudo-Hermitian quantum mechanics supersymmetry supercoherent states
2010/12/16
A new class of non-Hermitian Hamiltonians with real spectrum, which are written as a real linear combination of su(2) generators in the form H = ωJ3 + αJ− + βJ+,α 6= β, is analyzed.
Pointwise estimates for the ground states of some classes of positivity preserving operators
Hardy’s inequality ground state ultracontractivity Dirichlet form energy measure

We establish pointwise estimates for the ground states of some classes of posi-tivity preserving operators. The considered operators are negatively perturbed (by measures) strongly local Dirichlet ope...
