Granular matter is ubiquitous in nature and is present in diverse forms in important
engineering, industrial and natural processes. Particle-based computational modelling has …

We investigate the structural, vibrational, and mechanical properties of jammed packings of
deformable particles with shape degrees of freedom in three dimensions (3D). Each 3D …

Rigidity regulates the integrity and function of many physical and biological systems. This is
the first of two papers on the origin of rigidity, wherein we propose that “energetic rigidity,” in …

A wide range of disordered materials, from biological to geological assemblies, feature
discrete elements undergoing large shape changes. How significant geometrical variations …

This is the second paper devoted to energetic rigidity, in which we apply our formalism to
examples in two dimensions: Underconstrained random regular spring networks, vertex …

Collectively coordinated cell migration plays a role in tissue embryogenesis, cancer,
homeostasis and healing. To study these processes, different cell-based modelling …

We present PolyHoop, a lightweight standalone C++ implementation of a mechanical model
to simulate the dynamics of soft particles and cellular tissues in two dimensions. With only …

The spongy mesophyll is a complex, porous tissue found in plant leaves that enables carbon
capture and provides mechanical stability. Unlike many other biological tissues, which …

Quantum matter (novel phases of matter at zero temperature with exotic properties) is a
growing field with applications in its own domain, and in providing foundational support to …

Directed transport of a deformable particle is numerically investigated in a two-dimensional
periodic channel. Unlike the rigid particle, the deformable particle can pass through the …
