IPB Colloquium by dr Dragana Popovic
Dr Dragana Popovic from National High Magnetic Field Laboratory, Florida State University, Tallahassee, Florida, USA, gave IPB colloquium on "Glassy charge dynamics and magneto transport in lightly doped La_2CuO_4".
The central topic of the talk were how c-axis magneto transport and resistance noise study in La_1.97Sr_0.03CuO_4 reveals clear signatures of glassiness, such as hysteresis, memory, and slow, correlated dynamics, but only at temperatures (T) well below the spin glass transition temperature Tsg . The results strongly suggest the emergence of charge glassiness, or dynamic charge ordering, as a result of Coulomb interactions.
Before the talk professor Aleksandar Bogojevic, gave a brief exposition of dr Dragana Popovic work.
