Experimental capabilities with ultracold few-body systems
continue to advance rapidly in a number of contexts. This
talk will highlight two recent developments. First, the
observation of butterfly Rydbergmolecules with kilodebye
dipole moments (H. Ott's group in Kaiserslautern) opens
the door to the possibility of observing interesting
blockaded phases in one dimension. Second, experimental
observations of heavy-heavy-light Efimov physics in a
mixture of Cs and Li atoms (M. Weidemueller's and C.
Chin's groups) have sparked in-depth theoretical studies
that suggest intriguing new regimes where interference
minima compete and intertwine with resonances in
recombination.

Fermionic Exchange Symmetry: Quantifying its Influence
beyond
Pauli's Exclusion Principle


The Pauli exclusion principle has a strong impact on the
properties and the behavior of most fermionic quantum
systems. Remarkably, even stronger restrictions on
fermionic natural occupation numbers follow from the
fermionic exchange symmetry. We develop an operationally
meaningful measure which allows one to quantify the
potential physical relevance of those generalized Pauli
constraints beyond the well-established relevance of
Pauli's exclusion principle. It is based on a geometric
hierarchy induced by Pauli exclusion principle
constraints. The significance of that measure is
illustrated for a few-fermion model which also confirms
such nontrivial relevance of the generalized Pauli
constraints.

"ac-driven quantum ratchets with Bose-Einstein
condensates"


"I will start with a brief introduction into the symmetry
analysis followed by a crash-course on the Floquet
analysis of ac-driven quantum systems. Then I will show
how the symmetry analysis allows one to figure out the
prerequisites for the quantum ratchet transport to occur
and next helps to predict the direction of this
transport. Theoretical considerations will be illustrated
with the experimental results obtained by measuring
mobility of a Bose-Einstein condensate of rubi atoms
loaded into different ac-driven optical potentials.
Finally, some open problems and promising directions will
be discussed."

"Spin dependent phenomena in carbon nanotubes"


"...Carbon nanotubes possess exceptional electronic
properties and are ideal candidates to investigate
transport properties ofquantum systems of reduced
dimensions. In my talk I will in particular address
phenomena which occur due to the presence of spin and
isospin degrees of freedom as a result of the honeycomb
structure of the underlying graphene lattice."
