Beschreibung

One of the apparent difficulties for New Materials Physics is how to identify promising phase spaces to explore or study. In essence, with hundreds of thousands of possible compounds (known and unknown) to consider, how can promising materials be discovered? The design and discovery of new strongly correlated electron systems or quantum materials is essentially a negotiation with Nature. As with any negotiation, it is important to be as flexible as possible while still holding on to the key points that are vital. In this talk I will try to illustrate how desires can be translated into specific new materials growth efforts. For example, how “wanting a low degeneracy, topological non-trivial compound that we could readily study with ARPES” can lead directly to the identification and study of RhBi2. Another example is how a desire to discover new quantum critical materials can be translated into searches near collapsed tetragonal phase transitions or the study of ternary compounds that include an immiscible pair of elements. NOTE: one of the goals of this talk it to provide my theoretical colleagues some insight into how experimentalists translate complex theoretical ideas into very primitive attempts to shave the dice in this cosmic game of craps.
