The setting is an overdamped translational sector on an extended one-particle state space, where internal variables may encode orientations, species, or other hidden degrees of freedom. We show that broken detailed balance enters the response to spatial shift generators through a current-induced gauge anomaly, while the generator algebra itself remains unchanged. At the one-body level, this yields a localized hyperforce balance and an exact projection theorem that decomposes the translational entropy production into visible and hidden non-negative parts at arbitrary retained one-particle resolution. The resulting bounds depend only on equal-time one-body densities, currents, and force densities, and therefore avoid time reversal and full trajectory inference. For active Brownian particles, we show that the physically relevant retained variables are position and orientation, not position alone: position-only fields can be entirely blind to irreversibility even in mechanically static steady states. Brownian-dynamics simulations of ideal, homogeneous interacting, and slit-confined active Brownian particles confirm the theoretical predictions. Our results connect gauge response, coarse graining, and measurable irreversibility in active matter.","PeriodicalId":20085,"journal":{"name":"Physical review.

While cell-cell adhesion is known to regulate motion by shaping cell morphology and intercellular force balance, its dynamic, rate-dependent contributions to tissue behavior remain poorly understood. In this study, we examine how the dissipative nature of cell-cell adhesion influences tissue dynamics and collective migration using an extended vertex model with explicit junctional viscosity. Our findings reveal a nontrivial interplay between two distinct components of adhesion: An interfacial adhesion energy (energetic, rate-independent) contribution, which sets the effective junctional tension, and a dissipative (rate-dependent) contribution, which controls resistance to relative motion during cell rearrangements. We show that increasing the energetic component promotes migration by modifying cell shape and lowering the barrier to neighbor exchanges, whereas strengthening the dissipative component induces jamming and suppresses cell motion. Linear rheological analysis further demonstrates that, in the unjammed regime, vertex-model tissues exhibit power-law viscoelastic behavior, with adhesion modulating the power-law exponent and thereby controlling the spread of relaxation timescales. Together, these findings clarify the dual role of adhesion in governing tissue mechanics and rheology and provide a mechanistic framework for understanding the balance between fluidity and rigidity in epithelial monolayers.","PeriodicalId":20085,"journal":{"name":"Physical review.

To enable systematic exploration of the parameter space, we develop and validate a neural-network surrogate model that replicates the exact quantum dynamics with high fidelity, yielding computational savings of up to 2 orders of magnitude compared with direct simulation. The dynamical blockade described below is the central physical result of this work, and the surrogate model is the computational means by which we characterize it across the full parameter space. Our framework reveals a many-body charging blockade: when the battery dimensions are comparable to the charger's excitation number, charging efficiency falls well below its kinematic limit despite ample energy remaining in the charger. We identify the physical underpinnings of this blockade as the saturation of the charger's emission rate, which confines the system to a low-excitation subspace before the battery can access its most absorptive states. This mechanism is intrinsic to finite chargers and absent in conventional infinite-mode models. This blockade is robust across a range of Bargmann indices and persists in a standard Dicke charger, confirming that it is a general feature of finite-dimensional charging rather than a property specific to the SU(1,1) algebra. We further show that a large number of charger excitations improves efficiency and reduces variance at the same time, whereas the blockade regime degrades both metrics together. These findings identify a many-body constraint on collective quantum charging and provide guidelines for designing high-performance quantum energy storage systems.","PeriodicalId":20085,"journal":{"name":"Physical review.

Recently, this framework was extended to characterize quantum phase transitions of quantum Ising models by introducing the concepts of non-Hermitian parity-symmetry breaking and fidelity zeros. Here, we generalize the theory by studying a broad class of quantum models, including the XY, the XXZ, the XYZ, and the Z_{p} clock models in one dimension, subject to a complex magnetic field. For the XY, XXZ, and XYZ models, we find that the complex field breaks parity symmetry and induces oscillations of the ground state between the two parity sectors, giving rise to fidelity zeros within the ordered phases. For the Z_{3} clock model, the complex field splits the real part of the ground-state energy between the neutral sector (q=0) and the charged sectors (q=1,2), while preserving the degeneracy within the charged sector. Fidelity zeros arise only after projecting out one of the charged sectors. For the Z_{4} and Z_{5} clock models, the ground states are instead projected to oscillate between the neutral sector (q=0) and the charged sectors q=2 and q=1, respectively, giving rise to fidelity zeros. Finite-size scaling of these zeros yields critical exponents in full agreement with analytical predictions, demonstrating that this approach is applicable not only to the Ising model with Z_{2} symmetry, but also to more general Heisenberg-type models and systems with higher discrete symmetries.","PeriodicalId":20085,"journal":{"name":"Physical review.

Each node in GP(N,k) has a coordination number of z=3, and by varying the parameter k different connections between the nodes in the inner loop can be obtained. The objective is to study whether different connectivities between nodes in these graphs affect the system's response to an external field when the coordination number is fixed. This is of interest because critical behavior is absent for z≤3 on a random graph which has been solved exactly as well as on the honeycomb lattice in the context of RFIM. Using single-spin-flip Glauber dynamics at zero temperature, we compare the system's response with the known case of a z=3 random graph and the generalized Petersen graph for various connectivities k, albeit for the same z. Our study finds the absence of critical behavior on GP(N,k), highlighting the importance of the coordination number over varying connectivities between the nodes. Additionally, we explore the case of directed GP(N,k) and compare it with the undirected GP(N,k) results.","PeriodicalId":20085,"journal":{"name":"Physical review.
