## "The Universe in an Atom: how precision measurements of atomic spins can probe the universe's greatest mysteries," Friday, September 20, 12n, MH 606

### Derek Jackson Kimball, California State University - East Bay

Modern cosmology poses deep, unanswered questions about the nature of the universe:

## "Thermoelectric effects in nanostructures," Friday, October 25, 12n, MH 606

### David Sanchez, University of the Balearic Islands, Spain

Modern miniaturization technologies have the potential to dramatically alter the way we actually conceive energy production, transport and distribution. In particular, thermoelectric devices can provide important savings in energy consumption from recovery of waste heat and improved cooling protocols. However, the fundamentals of controlling and manipulating energy flow in nanostructures have not been fully understood yet. We will here discuss the latest developments in thermoelectricity of quantum conductors, emphasizing the role of symmetries, nonlinearities and time-dependent responses.

### Michael Campbell

Mike was a CSUF double major physics/math class of 1991 who went on to finish his PhD in math at UCLA in 1999 and then on to postdocs at UCI and UC Berkeley.

*and storage*costs are included. The problem then displays features in“phase transition” phenomena (like a piece of metal magnetizing at low temperature). That is pretty amazing, since it takes some heavy-duty tools to get to the discontinuities that characterize phase transitions, in say, a magnetic system. The can problem has discontinuity built in, so we bypass functional analysis, operator algebras, measure/probability theory, stochastic pde’s and all the other inaccessible tools to cut right to the chase. All that is needed is an understanding of first-semester calculus. As the price for storage increases, the optimal can changes from one with a square profile to one with a rectangular profile. This is essentially “symmetry breaking” in statistical mechanics. This talk will explore this open problem.
