Fano resonances and entanglement entropy
Viktor Eisler, Savannah Sterling Garmon
We study the entanglement in the ground state of a chain of free spinless fermions with a single side-coupled impurity. We find a logarithmic scaling for the entanglement entropy o…

Density of states and quantum phase transition in the thermodynamic limit of the Mermin central-spin model
Savannah Sterling Garmon, Pedro Ribeiro, Rémy Mosseri
We apply a spin-coherent states formalism to study the central-spin model with monochromatic bath and symmetric coupling (the Mermin model); in particular, we derive analytic expre…
