Entanglement and the Interplay between Staggered Fields and Couplings
Jenny Hide, Yoshifumi Nakata, Mio Murao
We investigate how the interplay between a staggered magnetic field and staggered coupling strength affects both ground state and thermal entanglement. Upon analytically calculatin…
Concurrence in Disordered Systems
Jenny Hide
Quantum systems exist at finite temperatures and are likely to be disordered to some level. Since applications of quantum information often rely on entanglement, we require methods…
A Steady State Entanglement Witness
Jenny Hide
We present a method for entanglement detection in steady state systems using a thermodynamic witness. To illustrate, we consider an example and find that for an XX spin chain, the…
Detecting Entanglement with Jarzynski's Equality
Jenny Hide, Vlatko Vedral
We present a method for detecting the entanglement of a state using non-equilibrium processes. A comparison of relative entropies allows us to construct an entanglement witness. Th…
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…
Witnessing Macroscopic Entanglement in a Staggered Magnetic Field
Jenny Hide, Wonmin Son, Ian Lawrie +1
We investigate macroscopic entanglement in an infinite XX spin-1/2 chain with staggered magnetic field, B_l=B+e^{-iπl}b. Using single-site entropy and by constructing an entangleme…
