Positive phase space transformation incompatible with classical physics
Wonmin Son, Johannes Kofler, M. S. Kim +2
Bell conjectured that a positive Wigner function does not allow violation of the inequalities imposed by local hidden variable theories. A requirement for this conjecture is "when…
Enhancing the Detection of Natural Thermal Entanglement with Disorder
Jenny Hide, Wonmin Son, Vlatko Vedral
Physical systems have some degree of disorder present in them. We discuss how to treat natural, thermal entanglement in any random macroscopic system from which a thermodynamic wit…
Quantum instability and edge entanglement in a quasi-long-range order
Wonmin Son, Luigi Amico, Francesco Plastina +1
We investigate the build-up of quasi-long-range order in the XX chain with transverse magnetic field at finite size. As the field is varied, the ground state of the system displays…
