The starting point is a Cahn-Hilliard-Landau-de Gennes description of the coexistence profile, coupled to Brinkman-screened Stokes hydrodynamics. Small perturbations are projected onto three interfacial degrees of freedom: the conserved height mode associated with translations of the coexistence profile, a scalar profile-distortion mode, and a transverse orientational mode corresponding to director rotations. In the screened hydrodynamic regime, activity generates a local analytic contribution, proportional to q^{2}, to the height-sector dynamics. This term competes with the passive conserved capillary relaxation, which enters at order q^{4}, and can destabilize the interface even when the homogeneous active nematic is below its bulk instability threshold. The scalar profile-distortion mode is gapped and can be eliminated at long wavelengths. The transverse orientational mode plays a different role: if its full relaxation rate is positive, it renormalizes the effective scalar height equation; if it remains soft, the long-wavelength instability is described by a coupled height-director mode. The resulting framework separates two issues that are often intertwined in active-interface problems. The first is the transport mechanism, which may be local and analytic for a screened diffuse interface or nonanalytic when long-ranged outer flow produces terms such as |q|. The second is the modal structure of the unstable branch, which may be predominantly heightlike or intrinsically coupled to director rotations.","PeriodicalId":20085,"journal":{"name":"Physical review.

Classical system reliability theory is formulated using real-valued probabilities and combinatorial aggregation and therefore lacks an intrinsic mathematical structure capable of encoding interaction strength, synchronization, and pathway competition. As a result, redundancy and vulnerability in highly coupled systems are often mischaracterized. This study introduces a quantum system reliability (QSR) framework that reformulates system reliability as a complex-valued field. In the proposed representation, the magnitude of each component amplitude corresponds to postevent functionality, while the phase encodes interaction induced by connectivity, redistribution, constraint release, and dependency. Because classical reliability contains no inherent phase information, this work rigorously defines reliability phase. It develops two independent extraction strategies: (1) a spectral-domain formulation based on discrete Fourier analysis of reliability fields, and (2) a quantum-field formulation derived from divergence, curl, and geometry-induced flux operators. Component reliabilities are encoded as complex amplitudes, and system reliability emerges through interference-aware aggregation rules that generalize classical series, parallel and inclusion-exclusion principles. The formulation preserves exact classical reliability under neutral-phase conditions while enabling constructive and destructive interference in the presence of dependencies. The framework is validated using benchmark networks, including cascading IEEE-118 data and interdependent graph models, demonstrating improved alignment with functional system behavior compared to classical connectivity-based metrics.","PeriodicalId":20085,"journal":{"name":"Physical review.

Two distinct interaction regimes are considered: the moderate, when the interaction energy is small compared to the trap energy, and the strong, when the interaction energy is comparable to the trap energy. In the moderate interaction regime, the SFF for the nonrotating case exhibits a dip-plateau structure with an absence of linear ramp, indicating integrable behavior, while for the single-vortex state the SFF exhibits a discernible linear ramp consistent with pseudo-integrable behavior. In the strong interaction regime, the nonrotating case exhibits emergence of a linear ramp with small time span in SFF, indicating that the system has moved further towards chaotic regime but continues to be pseudo-integrable. For the single-vortex and the multivortex states in a strong interaction regime, the span of the linear ramp in SFF increases progressively with rotation, indicating the system has moved into a strong chaotic regime consistent with Gaussian orthogonal ensemble. The power spectrum results with the exponent lying in the interval 1≲α≲2 are consistent with the SFF findings. An understanding of the observed crossover from integrable to quantum chaos is presented in terms of the macroscopic occupation of a single-particle quantum state-the Bose-Einstein condensation-and its depletion driven by interaction and rotation.","PeriodicalId":20085,"journal":{"name":"Physical review.

Time delay is ubiquitous in such systems, arising from finite signal propagation speeds and sensory processing lags; however, its structural form, whether symmetric or asymmetric, has received little attention. Here, we study a one-dimensional swarmalator model with asymmetric time delay, in which the delay enters only the self-interaction terms of the spatial and phase dynamics, breaking the symmetry assumed in prior work. Using initial conditions drawn uniformly from [-π,π] for both the position and phase variables, we identify various collective states, such as async, static phase wave, static π, and active π, and derive analytical stability boundaries for each state as functions of the coupling parameters and the delay. Our analysis reveals that the asymmetric delay structure fundamentally reshapes the collective phase diagram: in particular, for the asymmetric delay models, increasing the delay systematically expands the active π state at the expense of other ordered states. This contrasts with the symmetric delay model, which more strongly promotes unsteady states that are generally not well ordered. By providing closed-form stability conditions validated against numerical simulations, our work establishes that the internal structure of the delay, and not merely its magnitude, is a decisive factor in determining the emergent collective behavior of swarmalator populations.","PeriodicalId":20085,"journal":{"name":"Physical review.

Interactions with the surrounding fluid can reverse both this Hall drift and the advective drift along the driving direction, yet the microscopic collision-level mechanism behind these reversals remains unclear. Here we introduce a collision-level framework to interpret drift reversal, combining underdamped Brownian dynamics simulations with a reversal-collision effectiveness map. The map identifies the host-tracer interaction-force orientations that favor reversal. A coarse-grained description of the host-particle velocity-direction statistics then connects this particle-level mechanism to the many-particle dynamics. We find that increasing the odd mobility strength shifts the angular probability distribution toward reversal-effective sectors, promoting drift reversal. Particle inertia and packing fraction modulate the two reversals asymmetrically: larger inertia strengthens the reversed advective drift while suppressing the Hall reversal. Increasing packing fraction produces a nonmonotonic response in which both reversals first intensify and then weaken, with both drift components beginning to recover their normal directions at high densities. Together, these results give a particle-level description of drift reversal in interacting chiral fluids, and clarify how inertia and packing fraction influence nonequilibrium transport in systems with broken time-reversal and mirror symmetries.","PeriodicalId":20085,"journal":{"name":"Physical review.

When the total fidelity can be represented as a ratio of two quadratic forms (e.g., in the case of mapping a mixed state to a pure state, projective operators, unitary learning, and others), semidefinite programming (sdp) can be applied to solve the fidelity optimization problem with respect to the Choi matrix. A remarkable feature of sdp is that the optimization is convex, which allows the problem to be efficiently solved by a variety of numerical algorithms. We have tested several commercially available sdp solvers, all of which allowed for the reconstruction of quantum channels of different forms. A notable feature is that the Kraus rank of the obtained quantum channel typically comprises less than a few percent of its maximal possible value. This suggests that a relatively small Kraus rank quantum channel is typically sufficient to describe experimentally observed classical data. The theory was also applied to the problem of reconstructing projective operators from data. Finally, we discuss a classical computational model based on quantum channel transformation, performed and calculated on a classical computer, possibly hardware-optimized.","PeriodicalId":20085,"journal":{"name":"Physical review.
