Elastic lines on splayed columnar defects studied numerically
Viljo Petaja, Matti Sarjala, Mikko Alava +1
We investigate by exact optimization method properties of two- and three-dimensional systems of elastic lines in presence of splayed columnar disorder. The ground state of many lin…

Entanglement transition of elastic lines in a strongly disordered environment
Viljo Petaja, Mikko Alava, Heiko Rieger
We investigate by exact optimization the geometrical properties of three-dimensional elastic line systems with point disorder and hard-core repulsion. The line 'forests' become ent…
