Jenny Hoffman is interested in how electrons behave in novel
materials. Her research so far has focused on the high temperature
superconductor Bi2Sr2CaCu2O8+x.
She has used a scanning tunneling microscope to image the
emergence of a new electronic order in the quantized vortices
of Bi2Sr2CaCu2O8+x.
She has also introduced a new analysis technique, Fourier
transform scanning tunneling spectroscopy, to the study of
the cuprate superconductors. This technique allows the simultaneous
measurement of real-space and momentum-space properties of
the superconducting quasiparticles.
Research in the Hoffman lab will revolve around scanning
probe microscopies of exotic materials, with an initial focus
on unexplored regions of phase space in the high temperature
superconductors. An initial project will be the construction
of a low-temperature, high-field scanning tunneling microscope,
in order to investigate the field-dependent properties of
high-temperature superconductors and organic superconductors.
