1.1. Goals of this course

• bridge the gap between standard undergraduate CM course and frontier research
• introduction of topics, materials, and techniques that are commonly used in modern CMP

• basic understanding at the phenomenological level

• share the colorfulness, beauty, and excitement of modern CMP

• Foster free, independent, and critical thinking

1.2. Features of this course

• focus on experimental aspects of CMP
• lots of real data and experimental observations
• some exposure to materials and experimental techniques
• mainly phenomenological and descriptional
• along the historical path of discovery and understanding
• not very systematic, not very accurate

1.3. Condensed matter physics primer

• what is "condensed matter"?

my definition: materials with particle density $\sim 10^{23} / cm ^{3}$

• where is the name "condensed matter" from?

Philip Anderson and Volker Heine, in 1967 in Cambridge renamed "solid state theory group" to "condensed matter theory group"

• what do we study (mainly) in condensed matter physics?

the behavior of Electrons and Phonons

• How many condensed matter physicists are there?

$1 / 3$ of all physicists, biggest branch of modern physics

• features of Experimental CMP

a wide variety of topics, rapid progress, close interactions between theory, important driving force for cutting-edge technologies
