I describe a class of spin models with short-range plaquette interactions, whose static equilibrium properties are trivial, but which display glassy dynamics at low temperatures. These models have a dual description in terms of free defects subject to effective kinetic constraints, and are thus an explicit realization of the constrained dynamics picture of glassy systems.

This paper presents solvable examples of quantum many-body Hamiltonians of systems that are unable to reach their ground states as the environment temperature is lowered to absolute zero. These examples, three dimensional generalizations of quantum Hamiltonians proposed for topological quantum computing, 1) have no quenched disorder, 2) have solely local interactions, 3) have an exactly solvabl...

Motility-induced phase separation (MIPS), the phenomenon in which purely repulsive active particles undergo a liquid-gas separation, is among simplest and most widely studied examples of nonequilibrium transition. Here, we show that states MIPS coexistence are fact only metastable for three-dimensional Brownian over very broad range conditions, decaying at long times through an ordering transit...

The pursuit of two-dimensional (2D) borides, MBenes, has proven to be challenging, not the least because lack a suitable precursor prone deintercalation. Here, we studied room-temperature topochemical deintercalation lithium from layered polymorphs LiNiB compound with considerable amount Li stored in between [NiB] layers (33 at. % Li). Deintercalation leads novel metastable borides (Li?0.5NiB) ...

We study the glass formation in two- and three-dimensional Ising and Heisenberg spin systems subject to competing interactions and uniaxial anisotropy with a mean-field approach. In three dimensions, for sufficiently strong anisotropy the systems always modulate in a striped phase. Below a critical strength of the anisotropy, a glassy phase exists in a finite range of temperature, and it become...

We study the microstructural glass transition in diblock-copolymer melts using a thermodynamic replica approach. Our approach performs an expansion in terms of the natural smallness parameter--the inverse of the scaled degree of polymerization N--which allows us to systematically study the approach to mean-field behavior as the degree of polymerization increases. We find that in the limit of in...

We use computer simulations to study the glass transition of dense fluids made of polydisperse repulsive spheres. For hard particles, we vary the volume fraction, phi , and use compressible particles to explore finite temperatures, T>0 . In the hard sphere limit, our dynamic data show evidence of an avoided mode-coupling singularity near phi(MCT) is approximately 0.592; they are consistent with...
