Title: Quantum boomerang effect in systems without time reversal symmetry
Authors: Jakub Janarek, Beno\^it Gr\'emaud, Jakub Zakrzewski, and Dominique Delande
Abstract summary: In an Anderson localized system, a quantum particle with a nonzero initial velocity returns, on average, to its origin. Time reversal invariance was initially thought to be a necessary condition for the existence of this phenomenon. We theoretically analyze the impact of the symmetry breaking on the phenomenon using a one-dimensional system with a spin-orbit coupling.

Abstract: In an Anderson localized system, a quantum particle with a nonzero initial velocity returns, on average, to its origin. This recently discovered behavior is known as the quantum boomerang effect. Time reversal invariance was initially thought to be a necessary condition for the existence of this phenomenon. We theoretically analyze the impact of the symmetry breaking on the phenomenon using a one-dimensional system with a spin-orbit coupling and show that the time reversal invariance is not necessary for the boomerang effect to occur.

The behavior of quantum entanglement during scattering is identical to the behavior of initially classically correlated photons up to a constant factor equal to two. Our dedicated experiment with photons confirms these results and explains the "Puzzle of Decoherence" observed recently.

Real-time dynamics of false vacuum decay [49.1574468325115]
We investigate false vacuum decay of a relativistic scalar field in the metastable minimum of an asymmetric double-well potential. We employ the non-perturbative framework of the two-particle irreducible (2PI) quantum effective action at next-to-leading order in a large-N expansion.

Formulation of causality-preserving quantum time of arrival theory [0.0]
We revisit the quantum correction to the classical time of arrival to address the unphysical instantaneous arrival in the limit of zero initial momentum. We show that the vanishing of arrival time is due to the contamination of the causality-violating component of the initial wave packet.

Quantum quenches from an excited state [0.0]
We extend the theory of quantum quenches to the case in which before the quench the system is in an excited state. Oscillations staying undamped within the accessible time interval, far beyond the perturbative time scale, are nowadays observed in numerical simulations.

Quantum nonreciprocal interactions via dissipative gauge symmetry [18.218574433422535]
One-way nonreciprocal interactions between two quantum systems are typically described by a cascaded quantum master equation. We present a new approach for obtaining nonreciprocal quantum interactions that is completely distinct from cascaded quantum systems.

Qubit Decoherence and Symmetry Restoration through Real-Time Instantons [0.0]
We show that non-perturbative quantum effects lead to the symmetry restoration and result in exponentially small but finite qubit decoherence rate. Technically the symmetry restoration is due to real time instanton trajectories of the Keldysh path integral.

Nonlinear interferometry beyond classical limit facilitated by cyclic dynamics [18.236929748580867]
We present an approach that is broadly applicable to cyclic systems for implementing nonlinear interferometry without invoking time reversal. We implement such a 'closed-loop' nonlinear interferometer and achieve a metrological gain of $3.87_-0.95+0.91$ decibels over the classical limit for a total of 26500 atoms.

Observation of the Quantum Boomerang Effect [0.0]
We report the experimental observation of the quantum boomerang effect. As kicking destroys dynamical localization, the quantum boomerang effect also disappears. These results showcase a unique experimental probe of the underlying quantum nature of Anderson localized matter.

Quantum emulation of coherent backscattering in a system of superconducting qubits [45.82374977939355]
We use multi-pass Landau-Zener transitions at the avoided crossing of a highly-coherent superconducting qubit to emulate weak localization (WL) and universal conductance fluctuations (UCF) The higher coherence of this qubit enabled the realization of both effects, in contrast to earlier work arXiv:1204.6428, which successfully emulated UCF, but did not observe WL.
