Entanglement entropy in a boundary impurity model
Gregory Levine
Boundary impurities are known to dramatically alter certain bulk properties of 1+1 dimensional strongly correlated systems. The entanglement entropy of a zero temperature Luttinger…

Entanglement of a qubit with a single oscillator mode
G. C. Levine, V. N. Muthukumar
We solve a model of a qubit strongly coupled to a massive environmental oscillator mode where the qubit backaction is treated exactly. Using a Ginzburg-Landau formalism, we derive…
