NATO Science for Peace and Security Series
This Series presents the results of scientific meetings supported under the NATO
Programme:ScienceforPeaceandSecurity(SPS).
The NATO SPS Programme supports meetings in the following Key Priority areas: (1)
DefenceAgainstTerrorism;(2)CounteringotherThreatstoSecurityand(3)NATO,Partner
and Mediterranean Dialogue Country Priorities. The types of meeting supported are
generally “Advanced Study Institutes”and“Advanced Research Workshops”. The NATO
SPSSeriescollectstogethertheresultsofthesemeetings.Themeetingsarecoorganized

Dialogue” countries. The observations and recommendations made at the meetings, as

Preface
These proceedings of the NATO-ARW “Physical properties of nanosystems”
heldatthe “Yalta”Hotel,Yalta,Ukrainefrom28September–2October2009
emmergedasaresultofmanypresentationsanddiscussionsbetweenworkshop
participants.
Yalta workshop focused on several open problems in the theory of corre-
latedelectronsystems,nanophysicsandsensortechnology.Theprogrammeof
the workshopallowedpresentationsandopeneddiscussionsonseveralemerg-
ing modernresearchtopics,suchas ironpnictides. Theoreticaladvanceswere
tested against major experimental and technological achievements in related
materials.In the session on novel superconductors, the physical properties of
Fe-based and MgB2 and cuprate superconductors were discussed. Recent
advances in nanoscience have demonstrated that fundamentally new physi-
cal phenomena are found when systems are reduced in size down to dimen-
sions, comparable to the fundamental microscopic length scales of the inves-
tigated material. Latest developments in nanotechnology and measurement
techniques facilitate experimental investigationof the transport properties of
nanosystems. Special focus sessions were devoted to contemporary topics in
nanophysics, such as carbon nanotubes, graphene, magnetic nanostructures,
quantum dot, spintronics, molecular electronics, and quantum information
processing.
We are grateful to members of the International Advisory Committee:
F.Peeters and D.Logan for their consistent help and suggestions. We would
liketothanktheNATOScienceCommitteefortheessentialfinancialsupport,
without which the meeting could not have taken place. We also acknowledge
the National Academy of Science of Ukraine, Ministry of Ukraine for Educa-
tion andScience, J.StefanInstitute andFaculty ofMathematics and Physics,
University of Ljubljana, Slovenia for their generous support.
