Many seemingly intractable systems can be reduced to a system of interacting spins. Here, we introduce a system of artificial acoustic spins which are manipulated with ultrasound excitations associated with micro-cracking sources in thin sheets of crystals. Our spin-like system shows a peculiar relaxation mechanism after inducing an impulsive stress-ramp akin to splitting, or rupturing, of the system. Using real-time construction of correlations between spins states, we observe a clear… Expand


Observation of the Kibble–Zurek Mechanism in Microscopic Acoustic Crackling Noises
A weakening zone that forms near the moving crack tips is characterized using functional networks, and the scaling law between the formation of damages (defects) and the traversal rate across the critical point of transition is determined. Expand
Nonadiabatic study of dynamic electronic effects during brittle fracture of silicon.
The authors' simulations replicate the correct response of the crack tip velocity to the threshold critical energy release rate, a feat that is inaccessible to quantum mechanics methods or conventional force-field-based molecular dynamics. Expand
Complex networks and waveforms from acoustic emissions in laboratory earthquakes
Abstract. Understanding the physics of acoustic excitations emitted during the cracking of materials is one of the long-standing challenges for material scientists and geophysicists. In this study,Expand
Experimental observation of stick‐slip instability fronts
SUMMARY Stick-slip dynamic instability is a key mechanism governing frictional processes from microscale physics to earthquake faults and landslides; yet challenging questions are still open aboutExpand
Scaling of the shear rupture process from nucleation to dynamic propagation: Implications of geometric irregularity of the rupturing surfaces
A series of systematic, high-resolution laboratory experiments have been performed on the nucleation of propagating slip failure on preexisting faults having different surface roughnesses toExpand
Light cone dynamics and reverse Kibble-Zurek mechanism in two-dimensional superfluids following a quantum quench
We study the dynamics of the relative phase of a bilayer of two-dimensional superfluids after the two superfluids have been decoupled. We find that on short time scales the relative phase showsExpand
Quasiparticle engineering and entanglement propagation in a quantum many-body system
First, the entanglement distributed by quasiparticles as they trace out light-cone-like wavefronts is observed, and second, using the ability to tune the interaction range in the system, information propagation is observed in an experimental regime where the effective-light-cone picture does not apply.

Detachment fronts and the onset of dynamic friction
It is shown that the onset of frictional slip is governed by three different types of coherent crack-like fronts: these are observed by real-time visualization of the net contact area that forms the interface separating two blocks of like material. Expand
Correlation between nanosecond X-ray flashes and stick–slip friction in peeling tape
Relative motion between two contacting surfaces can produce visible light, called triboluminescence. This concentration of diffuse mechanical energy into electromagnetic radiation has previously beenExpand
Emission of charged particles from indentation fracture of rocks
IT has long been realized that earthquakes are often associated with various kinds of anomalous electromagnetic phenomena. These phenomena might be caused by rock failure in the Earth's crust, butExpand
