We establish a set of nonequilibrium quantum phase transitions in the Lipkin-Meshkov-Glick model under monochromatic modulation of the interparticle interaction. We show that the external driving induces a rich phase diagram that characterizes the multistability in the system. Interestingly, the number of stable configurations can be tuned by increasing the amplitude of the driving field. Furth...

In this paper we present a self-stabilizing program for solving a pursuer-evader problem in sensor networks. The program can be tuned for tracking speed or energy efficiency. In the program, sensor motes close to the evader dynamically maintain a “tracking” tree of depth that is always rooted at the evader. The pursuer, on the other hand, searches the sensor network until it reaches the trackin...

Fuzzy constraints must be ne-tuned for a certain task. However, such ne-tuning cannot be done for all possible instantiations of a problem, and thus is generally done on protypical constraints. These templates are applied during run-time to a certain actual situation, i.e., dynamically adapted and applied only where necessary. This paper describes issues arising from the existance of such dynam...

Localized surface plasmon absorption features arise at high doping levels in semiconductor nanocrystals, appearing in the near-infrared range. Here we show that the surface plasmons of tin-doped indium oxide nanocrystal films can be dynamically and reversibly tuned by postsynthetic electrochemical modulation of the electron concentration. Without ion intercalation and the associated material de...

We investigate the nature of the dynamically inactive phase of a simple symmetric exclusion process on a ring. We find that as the system’s activity is tuned to a lower-than-average value the particles progressively lump into a single cluster, thereby forming a kink in the density profile. All dynamical regimes, and their finite size range of validity, are explicitly determined. ‡ vivien.lecomt...

High-quality continuous (GO) thin films are prepared by a self-assembly method. Z-scan measurements during the laser-induced reduction process unveil in situ nonlinear responses in the GO film. Third-order nonlinear responses of the GO film can be tuned dynamically by varying the laser input fluence. GO thin films with tunable nonlinear responses and versatile patterning opportunities by using ...

Gyroscope for rotation sensing plays a key role in inertial navigation systems. Developing more precise gyroscopes than the conventional ones bounded by classical shot-noise limit using quantum resources has attracted much attention. However, existing gyroscope schemes suffer severe deterioration under influence of decoherence, which is called no-go theorem noisy metrology. Here, two quantized ...

This paper describes a programmable switch architecture that can be dynamically tuned to support flexible quality of service metrics for flows in the Internet. The switch architecture consists of six key components: scheduling, flow aggregation, queueing, packet-level admission control, packet dropping, and feedback. We show that it is possible to achieve a wide range of QoS behavior ranging fr...
