CodeIt: Self-Improving Language Models with Prioritized Hindsight Replay Open
Large language models are increasingly solving tasks that are commonly believed to require human-level reasoning ability. However, these models still perform very poorly on benchmarks of general intelligence such as the Abstraction and Rea…

Learning lattice quantum field theories with equivariant continuous flows Open
We propose a novel machine learning method for sampling from the high-dimensional probability distributions of Lattice Field Theories, which is based on a single neural ODE layer and incorporates the full symmetries of the problem. We test…

Robust Scheduling with GFlowNets Open
Finding the best way to schedule operations in a computation graph is a classical NP-hard problem which is central to compiler optimization. However, evaluating the goodness of a schedule on the target hardware can be very time-consuming. …

Neural Topological Ordering for Computation Graphs Open
Recent works on machine learning for combinatorial optimization have shown that learning based approaches can outperform heuristic methods in terms of speed and performance. In this paper, we consider the problem of finding an optimal topo…

Low-frequency vibrational spectrum of mean-field disordered systems Open
We study a recently introduced and exactly solvable mean-field model for the density of vibrational states D(omega) of a structurally disordered system. The model is formulated as a collection of disordered anharmonic oscillators, with ran…

Finite-size study of the athermal quasistatic yielding transition in structural glasses Open
We present a finite-size study of the athermal quasistatic yielding transition in structural glasses featuring a wide range of mechanical disorder. We find a crossover from gradual yielding in small systems, to a macroscopic discontinuous …

Pinching a glass reveals key properties of its soft spots Open
Significance Glasses form when liquids are quickly cooled. Many of the properties of glasses are universal—i.e., independent of their composition and the liquid-phase temperature from which they were cooled. One such property is the …

What can be learnt from pinching a glass Open
It is now well established that glasses feature quasilocalized nonphononic excitations, which follow a universal $\omega^4$ density of states in the limit of low frequencies $\omega$. All glass-specific properties, such as the dependence o…

Particle pinning suppresses spinodal criticality in the shear-banding instability Open
Strained amorphous solids often fail mechanically by creating a shear band. It had been understood that the shear-banding instability is usefully described as crossing a spinodal point (with disorder) in an appropriate thermodynamic descri…

Wave attenuation in glasses: Rayleigh and generalized-Rayleigh scattering scaling Open
The attenuation of long-wavelength phonons (waves) by glassy disorder plays a central role in various glass anomalies, yet it is neither fully characterized nor fully understood. Of particular importance is the scaling of the attenuation r…

Protocol dependence of plasticity in ultrastable amorphous solids Open
While perfect crystals may exhibit a purely elastic response to shear all the way to yielding, the response of amorphous solids is punctuated by plastic events. The prevalence of this plasticity depends on the number of particles N of the …

Robustness of mean field theory for hard sphere models Open
In very recent work the mean field theory of the jamming transition in infinite-dimensional hard sphere models was presented. Surprisingly, this theory predicts quantitatively the numerically determined characteristics of jamming in two an…

Mechanical failure in amorphous solids: Scale-free spinodal criticality Open
The mechanical failure of amorphous media is a ubiquitous phenomenon from material engineering to geology. It has been noticed for a long time that the phenomenon is "scale-free," indicating some type of criticality. In spite of attempts t…

Shear bands as manifestation of a criticality in yielding amorphous solids Open
Significance The art of making structural, polymeric, and metallic glasses is rapidly developing with many applications. A limitation is that, under increasing external strain, all amorphous solids have a yield stress, which when exceeded,…

Emergent interparticle interactions in thermal amorphous solids Open
Amorphous media at finite temperatures, be them liquids, colloids, or glasses, are made of interacting particles that move chaotically due to thermal energy, continuously colliding and scattering off each other. When the average configurat…

Breakdown of nonlinear elasticity in amorphous solids at finite temperatures Open
It is known [H. G. E. Hentschel et al., Phys. Rev. E 83, 061101 (2011)PLEEE81539-375510.1103/PhysRevE.83.061101] that amorphous solids at zero temperature do not possess a nonlinear elasticity theory: besides the shear modulus, which exist…

Mechanical Yield in Amorphous Solids: A First-Order Phase Transition Open
Amorphous solids yield at a critical value of the strain (in strain-controlled experiments); for larger strains, the average stress can no longer increase-the system displays an elastoplastic steady state. A long-standing riddle in the mat…
