Liquid crystals (LCs) can host robust topological defect structures that essentially determine their optical and elastic properties. Although recent experimental progress enables precise control over localization and dynamics of nematic LC defects, t

Lindbladian dissipation of strongly-correlated quantum matter

Autor: Sá, Lucas, Ribeiro, Pedro, Prosen, Tomaž

Publikováno v: Physical review research, vol. 4, no. 2, pp. l022068-1-l022068-8, 2022.

We propose the Sachdev-Ye-Kitaev Lindbladian as a paradigmatic solvable model of dissipative many-body quantum chaos. It describes N strongly coupled Majorana fermions with random all-to-all interactions, with unitary evolution given by a quartic Ham

In liquid crystal applications, boundary conditions are essential to ensuring suitable bulk molecular orientation and a deterministic response to external fields. Be it confinement to a droplet or a shell, a glass plate, or an interface with air or a

Quasicrystalline ordering was first observed in synthetic multi-component metallic alloys. These solid state materials exhibit quasicrystalline atomic ordering at nanometer length scales. Softmatter systems are another class of versatile materials th

Physical Review X, Vol 9, Iss 3, p 031051 (2019)

Active nematics contain topological defects which under sufficient activity move, create and annihilate in a chaotic quasi-steady state, called active turbulence. However, understanding active defects under confinement is an open challenge, especiall

Droplets of active fluid form a dynamically self-assembled material based on the cross-talk between active and passive defects.
The formation of emulsions from multiple immiscible fluids is governed by classical concepts such as surface tension,

Publikováno v: Advanced functional materials, vol. 32, no. 44, 2205546, 2022.

Physically intelligent micro-robotic systems exploit information embedded in micro-robots, their colloidal cargo, and their milieu to interact, assemble, and form functional structures. Nonlinear anisotropic fluids such as nematic liquid crystals (NL

Charge profiles in liquid electrolytes are of crucial importance for applications, such as supercapacitors, fuel cells, batteries, or the self-assembly of particles in colloidal or biological settings. However, creating localised (screened) charge pr
