*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.
