Course Description

Soft Matter

Program

Nanosciences and Nanotechnologies, third-level study programme

Lecturers:

prof. dr. Samo Kralj

Goals:

Student get basic knowledge on soft matter systems and also get acquainted with several universal phenomena, that link them to other systems in nature (e.g. particle physics, cosmology…).

Content:

• Soft matter, general characteristics
• Interactions, atomic and molecular structures
• Continuum description and order parameter
• Phase and structural transitions
• Physics of defects, universalities, analogous systems (in solid state, particle physics and cosmology)
• Surface phenomena, thin films, wetting, anchoring
• Stability of colloidal patterns, gels
• Polymers
• Phase separation
• Applications
