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…
Measurement-induced phase transitions in monitored infinite-range interacting systems
Anna Delmonte, Zejian Li, Gianluca Passarelli +4
A key challenge in observing measurement-induced phase transitions is the mitigation of the post-selection barrier, which causes the reproducibility of specific sequences of measur…
A dissipation-induced superradiant transition in a strontium cavity-QED system
Eric Yilun Song, Diego Barberena, Dylan J. Young +7
In cavity quantum electrodynamics (QED), emitters and a resonator are coupled together to enable precise studies of quantum light-matter interactions. Over the past few decades, th…
Trade-offs between unitary and measurement induced spin squeezing in cavity QED
Diego Barberena, Anjun Chu, James K. Thompson +1
We study the combined effects of measurements and unitary evolution on the preparation of spin squeezing in an ensemble of atoms interacting with a single electromagnetic field mod…
