A "squeezed polaron" variational wavefunction for the spin boson model
Diego Barberena, Nigel Cooper
The localization transition of the sub-Ohmic spin-boson model generates boson bath correlations that are, at low frequencies, analytically inaccessible to standard coherent-state-p…

Dissipative generation of spin squeezing in the resolved vacuum Rabi splitting limit
Edwin Chaparro, Eric Yilun Song, Diego Barberena +3
Harnessing dissipation in the presence of strong symmetries has recently emerged as a promising route for generating entanglement in atomic clocks. However, previous proposals reli…
