Delocalization of interacting directed polymers on a periodic substrate: Localization length and critical exponents from non-Hermitian spectra
Abhijeet Melkani, Alexander Patapoff, Jayson Paulose
We study a classical model of thermally fluctuating polymers confined to two dimensions, experiencing a grooved periodic potential, and subject to pulling forces both along and tra…
Long-ranged order and flow alignment in sheared atic liquid crystals
Luca Giomi, John Toner, Niladri Sarkar
We formulate a hydrodynamic theory of atic liquid crystals, namely two-dimensional anisotropic fluids endowed with generic fold rotational symmetry. Our approach, based on…
Non-dispersive one-way signal amplification in sonic metamaterials
Noah Kruss, Jayson Paulose
Parametric amplification -- injecting energy into waves via periodic modulation of system parameters -- is typically restricted to specific multiples of the modulation frequency. H…
Hydrodynamic theory of atic liquid crystals
Luca Giomi, John Toner, Niladri Sarkar
We formulate a comprehensive hydrodynamic theory of two-dimensional liquid crystals with generic fold rotational symmetry, also known as atics, of which mematics an…
Marginally compact phase and ordered ground states in a model polymer with side spheres
Tatjana Škrbić, Trinh Xuan Hoang, Achille Giacometti +2
We present the results of a quantitative study of the phase behavior of a model polymer chain with side spheres using two independent computer simulation techniques. We find that t…
Marginal Stability Enables Memory Training in Jammed Solids
Francesco Arceri, Eric I. Corwin, Varda F. Hagh
Memory encoding by cyclic shear is a reliable process to store information in jammed solids, yet its underlying mechanism and its connection to the amorphous structure are not full…
