Description |
**Outline random matrix theory notions for conductance without proof. **Describe without algebra what can be done in this case and in several related cases (analytical results for large channel-number asymptotics). **Describe the formulation of the spin conductance in this language, and how we are stuck when it comes to calculating large-channel number asymptotics. Ask audience to think of possible alternate strategies. **Outline the only success we have had, which is Vikram's method of using L'hospital rule type manipulations to get very answers for several finite N. **Describe some made-up quantities for which we can do the calculation and ask the audience if they know of contexts in which such made-up quantities are the natural objects. |
