Okinawa School in Physics: Coherent Quantum Dynamics 2014


Place: Onna-son (island of Okinawa), Japan

Deadline for applications: May 1st, 2014

For more information:

The study of quantum coherent dynamics is currently one of the most active and exciting areas in physics. It holds the promise for the development of new technologies (quantum computing, quantum metrology,...) and, at the same time, has already delivered insights into the foundations of quantum mechanics. Its fast moving pace, in both theory and experiment, has attracted many young researchers and summer schools have become an integral part of the education and networking of students.

The school will consist of lectures delivered by international experts on fundamental problems of the area.  These will be supplemented by accessible presentations (colloquia) on cutting-edge research problems.  Additionally, we will organise problem solving sessions, which are partly tutorial style and partly open-ended, and two sessions on (English language) presentation skills. All participants will be required to present a poster based on their current research.

Thursday 31. July 2014

IMPRS get-together


Place: MPL / Large seminar room (*435)

Organisation: Luo Qi (IOIP / Quantum Radiation)

Talk: Quantum Imaging with Undetected Photons

Speaker: Dr. Radek Lapkiewicz (Institute for Quantum Optics and Quantum Information - Vienna; Research group: Zeilinger Group)


Indistinguishable quantum states interfere, but the mere possibility of obtaining information that could distinguish between overlapping states inhibits quantum interference. Quantum imaging can outperform classical imaging or even have entirely new features. We introduce and experimentally demonstrate a quantum imaging concept that relies on the indistinguishability of the possible sources of a photon that remains undetected. Our experiment uses pair creation in two separate down-conversion crystals. While the photons passing through the object are never detected, we obtain images exclusively with the sister photons that do not interact with the object. Therefore the object to be imaged can be either opaque or invisible to the detected photons.

MPL Distinguished Lecturer Series
From Ultracold Fermi Gases to Neutron Stars



Prof. Christophe Salomon (Ecole Normale Supérieure, Paris, France)


MPL / large seminar room (*435)


Superconductivity and superfluidity are spectacular macroscopic manifestations of genuine quantum collective effects with, today, vast domains of applications. In this family of quantum solids or fluids, ultracold gases and polaritons are the last born.


Thanks to the great flexibility of laser cooling and trapping methods, ultracold gases offer to study these quantum correlated systems with a new twist. It is possible for instance to tune the strength and sign of the interaction between atoms. Optical lattices, realized by interfering laser beams, create periodic optical potentials that mimic the crystalline potential seen by electrons in solids. Controlled disorder can be introduced to study the localization of matter-waves predicted by P.W. Anderson more than 50 years ago. Dilute atomic gases can thus be considered as model systems to address some pending problem in Many-Body physics that occur in condensed matter systems, nuclear physics, and astrophysics.


In this talk, we will discuss the seemingly simplest case of attractive spin 1/2 fermions with tunable interaction. We will show that the gas properties can continuously change from those of weakly interacting Cooper pairs described by Bardeen-Cooper-Schrieffer theory to those of strongly bound molecules undergoing Bose-Einstein condensation. A new imaging method enable us to probe with high precision the thermodynamics of locally homogeneous ultracold gases [1,2,3] and to perform stringent tests of recent many-body theories.  The equation of state of fermions has been measured as a function of interaction strength and temperature. Despite orders of magnitude difference in density and temperature, our equation of state can be used to describe low density neutron matter such as the outer shell of neutron stars. We will finally describe our recent production with Lithium isotopes of a dilute mixture of a Bose superfluid with a Fermi superfluid [4], a long thought goal of helium 4 and helium 3 quantum liquids.
