Title: Entanglement autodistillation from particle decays
Authors: J. A. Aguilar-Saavedra, J. A. Casas,
Abstract summary: We show that for a spin-entangled pair of particles the entanglement of the system can increase after the decay of one particle. This unique phenomenon has no equivalent for stable particles and could be observable in top pair production at a high-energy polarized $e+ e-$r.

Abstract: Particle decays do not constitute a spin ``measurement'' in the quantum-mechanical sense, but still modify the spin state, in particular for an entangled system. We show that for a spin-entangled pair of particles the entanglement of the system can increase after the decay of one particle. This unique phenomenon has no equivalent for stable particles and could be observable in top pair production at a high-energy polarized $e^+ e^-$ collider.

We study entanglement properties of the three-body $Htogamma lbarl$ decays (for $l=e,mu,tau$) within the context of the Standard Model. Our aim is to elucidate the distribution of entanglement between the final photon, lepton and antilepton across the phase-space.

Spin dynamics and dark particle in a weak-coupled quantum Ising ladder with $\mathcal{D}_8^{(1)}$ spectrum [7.16653440475268]
Emergent Ising$_h2$ integrability is anticipated in a quantum Ising ladder composed of two weakly coupled, critical transverse field Ising chains. We show that the selection rule to the form factor, which is inherent in the intrinsic charge-parity $mathcalC$ of the Ising$_h2$ particles, causes a significant result. The long lifetime of dark particle suggests its potential as a stable qubit for advancing quantum information technology.

The strongly driven Fermi polaron [49.81410781350196]
Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems. We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons. We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

Intrinsic quantum dynamics of particles in brane gravity [0.0]
We show that the stability of particle trajectories on the brane gives us the Bohr--Sommerfeld quantization condition. The particle's motion along the extra dimension allows us to formulate a geometrical version of the uncertainty principle. We show that the particle's motion along the extra dimension yields a quantized energy spectrum for bound states.

We study theoretically repelling quantum states of two spinless particles in a one-dimensional tight-binding model. We demonstrate, that when the particles are not identical, their interaction drives nontrivial correlated two-particle states.

On free fall of fermions and antifermions [0.0]
We propose a model describing spin-half quantum particles in curved spacetime. We find that spin precesses in a normal Fermi frame, even in the absence of torsion. We also find that (elementary) fermions and antifermions are indistinguishable in gravity.

We show that, when a wavefunction is boosted, its tails travel one to the past and the other to the future. The surprising implication is that, in a quantum world, decay probabilities can never be Lorentz-invariant.

Experimental observation of thermalization with noncommuting charges [53.122045119395594]
Noncommuting charges have emerged as a subfield at the intersection of quantum thermodynamics and quantum information. We simulate a Heisenberg evolution using laser-induced entangling interactions and collective spin rotations. We find that small subsystems equilibrate to near a recently predicted non-Abelian thermal state.

Observation-dependent suppression and enhancement of two-photon coincidences by tailored losses [68.8204255655161]
Hong-Ou-Mandel (HOM) effect can lead to a perfect suppression of two-particle coincidences between the output ports of a balanced beam splitter. In this work, we demonstrate experimentally that the two-particle coincidence statistics of two bosons can instead be seamlessly tuned to substantial enhancement. Our findings reveal a new approach to harnessing non-Hermitian settings for the manipulation of multi-particle quantum states.
