<font size="4"><b>Chirality and spin in organic molecules</b></font><br>
<br>
<div class="abstract tex">
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.
