*Chirality and spin in organic molecules*
In the late 19th century, Louis Pasteur discovered that biology shows a
preference for molecules with a specific handedness. Ever since,
researchers have been trying to understand the origin of life's
homochirality and its implications. For example, electron transport in
organisms, an essential part of basic biological processes such as
respiration and photosynthesis, is realized via insulating helical
molecules. Recent studies further found that the transmission
probability of electrons through such molecules is strongly
spin-dependent, with the preferred spin direction set by the chirality.
This direct connection between spin and chirality raises numerous
fundamental questions. It thus opens a new arena of research at the
interface between biology and quantum physics. In my talk, I will review
the most important experimental findings and describe a theoretical
model that explains the origin of spin-dependent transport: The helical
geometry induces robust spin filtering accompanied by, and intimately
related to, strongly enhanced overall transmission through chiral
molecules. In particular, I will focus on spin-selectivity in the chiral
system with strong electron-phonon interactions. Finally, I will present
some ideas for integrating organic molecules into solid-state devices
for various applications.
