Highlights of Symmetry Groups
Giampiero Esposito, Giuseppe Marmo
The concepts of symmetry and symmetry groups are at the heart of several developments in modern theoretical and mathematical physics. The present paper is devoted to a number of se…
On the meaning and interpretation of Tomography in abstract Hilbert spaces
V. I. Man'ko, G. Marmo, A. Simoni +3
The mechanism of describing quantum states by standard probability (tomographic one) instead of wave function or density matrix is elucidated. Quantum tomography is formulated in a…
Partial scaling transform of multiqubit states as a criterion of separability
C. Lupo, V. Man'ko, G. Marmo +1
The partial scaling transform of the density matrix for multiqubit states is introduced to detect entanglement of quantum states. The transform contains partial transposition as a…
Alternative Algebraic Structures from Bi-Hamiltonian Quantum Systems
G. Marmo, G. Scolarici, A. Simoni +1
We discuss the alternative algebraic structures on the manifold of quantum states arising from alternative Hermitian structures associated with quantum bi-Hamiltonian systems. We a…
Phase-space descriptions of operators and the Wigner distribution in quantum mechanics II. The finite dimensional case
S. Chaturvedi, E. Ercolessi, G. Marmo +3
A complete solution to the problem of setting up Wigner distribution for N-level quantum systems is presented. The scheme makes use of some of the ideas introduced by Dirac in the…
Phase-space descriptions of operators and the Wigner distribution in quantum mechanics I. A Dirac inspired view
S. Chaturvedi, E. Ercolessi, G. Marmo +3
Drawing inspiration from Dirac's work on functions of non commuting observables, we develop a fresh approach to phase space descriptions of operators and the Wigner distribution in…
