Here, we shall post materials related to scientific talks and discussions.

Overview of the program (organizational meeting on Monday, July 13, 2015)


Suggested Big Questions during the meeting:

1. What are new phases of matter with spin-orbit coupling + interaction ?
2. Can one experimentally engineer desired materials/phases ?
3. What are experimental tools to detect topological phases such as spin liquids and SPT (symmetry protected topological) phases ? Is the spin-orbit coupling helpful for realizing such purposes ?

Examples related to the above questions which we will discuss during the workshop:

1. Realizing topological materials/phases (weak or strong interactions) such as topological insulators, topological semimetals, topological Kondo insulators; Understanding the role of electron interaction.

2. Spin-orbital Mott insulators: beyond Heisenberg model (due to spin-orbit coupling and multi-orbital interactions such as Hunds coupling); Doping effects - hole vs electron doping; comparison/contrast to high Tc Cuprates; Possibilities of (topological) superconductors upon doping.

3. Spin-orbital liquid and Spin liquid; bond-dependent spin exchanges (such as Kitaev interaction) as a new avenue to realize spin liquid phases in addition to the usual route via geometrical frustration. The roles of such interactions for nearby magnetically-ordered (or other broken symmetry) phases.

4. "Correlated" topological insulators:
Models with more realistic interactions for interacting SPT; building intuition about possible realizations of interacting SPT; How can we use the strong spin-orbit coupling + interaction to realize such phases; Flat band systems - interactions on the partially filled flat band as a new route to realize some of the "correlated" topological phases. Coupled wire construction ?

5. Topological superconductors and possible candidate materials; Majorana fermions;
Sr2RuO4 as multi-orbital (topological ?) superconductor; quantum wire with strong spin-orbit coupling coupled to superconductor; TI surface coupled to superconductor

6. Engineered Platforms such as Heterostructures; use strain or substrates or chemical composition to control the nature/properties of phases (e.g. SrIrO3/SrTiO3 superlattices)
