- Abstract: We analyse the quantum backflow effect and extend it, as a limiting
constraint to its spatial extent, for scattering situations in the presence of
a purely transmitting discontinuous jump-defect. Analytical and numerical
comparisons are made with a different situation in which a defect is
represented by a $\delta$ function potential. Furthermore, we make the analysis
compatible with conservation laws.

- Flux-pump induced degradation of $T_1$ for dissipative cat qubits [42.110730614476104]
Dissipative stabilization of cat qubits autonomously corrects for bit flip errors by ensuring that reservoir-engineered two-photon losses dominate over other mechanisms inducing phase flip errors.
We analyze the dressing of relaxation processes under drives in time-dependent Schrieffer-Wolff perturbation theory for weakly anharmonic bosonic degrees of freedom.
We find that spurious single-photon decay rates can increase under the action of the parametric pump that generates the required interactions for cat-qubit stabilization.

We present an exact solution for the steady state of the transverse-field Ising model in the limit of infinite-range interactions.
Our solution holds despite the lack of any collective spin symmetry or even permutation symmetry.
It allows us to investigate first- and second-order dissipative phase transitions, driven-dissipative criticality, and captures the emergence of a surprising "spin blockade" phenomenon.
