[LA-SiGMA] LASiGMA Seminar Reminder, Wednesday, November 20th - Dr. Dan Dessau , 3:30pm at Louisiana State University

[sjlee at cct.lsu.edu]

Dear All,



As a reminder, Dr. Dan Dessau of the University of Colorado will be  
giving a seminar today at 3:30pm in 1008B at the Digital Media Center at
the Louisiana State University. The title of his talk is "What Sets the Tc
in Cuprate High Temperature Superconductors (plus some recent work on doped
Mott-like iridates)."



Abstract:

We have developed a new variant of angle-resolved photoemission spectroscopy
(ARPES) that gives greatly improved accuracy of gap measurements compared to
all other spectroscopic probes and also allows us to make the first
quantitative extraction of the pair-breaking scattering rates. The results
from this new method give critical new insights into the origin of
pseudogaps, Fermi arcs, and superconductive pairing in the cuprate
superconductors, helping us answer the critical question

"What sets the Tc?"



Following this I will present recent results from some iridium oxides, which
mix strong spin orbit coupling with correlation (Mott) effects. When doped
with carriers, many of the iconic properties of the cuprates such as Fermi
arcs and pseudogaps can also be found in these compounds, indicating that
these materials should become a fertile playground for the study of
correlated electron matter.





Biography:

Dan Dessau received his PhD in Applied Physics from Stanford University in
1993, after which he accepted a DOE Distinguished Postdoctoral Fellowship at
SLAC/SSRL, Stanford University.  He joined the Physics Department,
University of Colorado Boulder in 1995, winning an ONR young investigator
award and an NSF CAREER award.  He has been at the forefront of
spectroscopies of correlated systems for many years, making seminal early
contributions on the pairing symmetry and pseudogaps in cuprates and on the
nature of the colossal magnetoresistance in manganites.  He originated the
techniques of laser-ARPES and the new TDoS method of ARPES analysis.
