Merlion Funding for Martial Duchamp's team

MajuLab editor — 2019-02-04T09:28:56Z

The PHC Merlion Program (Hubert Curien Partnership) is a research mobility funding program, managed by the French Institute of Singapore (IFS), and conducted with our Singaporean partners, which initiates and supports the development of scientific cooperation between French and Singaporean laboratories.

Here is the details of the selected projects:

This project consists in realizing the first operation of a Solid Oxide Fuel Cell (SOFC) in situ in an Environmental Transmission Electron Microscope (ETEM) at different temperatures.

This approach will provide structural and chemical insights at the nanoscale, while the device is converting the chemical energy of a fuel directly into electricity. Through this Merlion Project, the CNRS French team will benefit from the expertise in sample preparation at Nanyang Technological University, and the Singaporean team will take advantage of environmental TEM experiments at CLYM at University of Lyon (a node of the METSA network). SOFC samples are obtained through an existing collaboration with Dr. Quentin Jeangros (Swiss Federal Institute of Lausanne, EPFL).'

MajuLab's team article as Editor's Choice at Phys. Rev. A.

MajuLab editor — 2018-10-11T06:27:57Z

Matteo Rizzi, Christian Miniatura, Anna Minguzzi, and Patrizia Vignolo Phys. Rev. A 98, 043607 – Published 4 October 2018

The relation between 2-body and many-body physics is often an important point for the comprehension and the description of strongly-correlated quantum systems.

A celebrated example is provided by homogeneous 1D interacting systems solvable by the Bethe Ansatz, such as bosons and fermions with contact interactions. In such a case, the N-body solution can be exactly expressed as a function of a product of two-body scattering contributions.

A crucial observable for a 1D system of N particles with contact interactions of strength g is the so-called Tan's contact parameter C(N,g), characterizing the asymptotic behavior of the 1-body momentum distribution n(k) which decays algebraically like C(N,g)/k^4 at large momenta.

The contact parameter is also determined by the probability density of finding 2 particles at a vanishing distance and embeds information on the interaction energy and the density-density correlation function. It is a univocal measure of the wavefunction symmetry of fermionic and/or bosonic mixtures.

In our paper, we have shown that the contact parameter can be simply and accurately obtained from an appropriate rescaling of the 2-body contact parameter. Indeed, almost all the dependence of the contact on the number of particles can be embedded in the contact at infinite interactions for any number of particles.

Our results seem to be general and not to depend on the particle statistics.
They thus show the fundamental role of the contact, likely due to its local 2-body correlation nature, and suggest a change of paradigm in the study of interacting quantum systems, giving a more fundamental role to the contact parameter than to the energy.

Our work constitutes an important step forward in understanding the effects of correlations and interactions in 1D interacting boson and fermion mixtures.

Nature Communications publication by David Wilkowski's group - CQT//NTU

MajuLab editor — 2018-10-03T06:48:36Z

CQT researchers have realized a quantum version of the famous ‘Foucault's pendulum' in a cloud of cold atoms – opening the door to simulation of fundamental phenomena in quantum physics. The approach also offers a sensitive way to measure the cloud's temperature.

The research by the group of David Wilkowski, a CQT Research Associate Professor based at the Nanyang Technological University, was published 4 September in Nature Communications. The team worked with a cloud of some 10,000 strontium atoms (87Sr) cooled to near absolute zero, demonstrating a phenomenon precisely referred to as a ‘non-Abelian geometric transformation'.

Swings and roundabouts

Foucault's pendulum is a staple exhibit of science centres worldwide. The direction in which a simple pendulum swings changes during the day, without the pendulum being touched. The effect is due to the rotation of the Earth. Imagine a pendulum at the North Pole: it swings in a fixed plane as the Earth rotates beneath it, making it appear, to someone on Earth, that the plane of motion of the pendulum precesses. This effect appears for a pendulum suspended freely anywhere except on the Equator.

In the quantum world, the same kind of precession can occur in the ‘state vector' that describes the properties of quantum system. In the experiments in David's group, the team are looking at the orientation of the atoms' spin. The phase of laser light shone onto the atoms acts something like the Earth's rotation, causing the spins to precess.

What's more, the quantum effect has a feature not found in the classical world. In certain circumstances, the transformations of the atom spins can be ‘non-Abelian'. This means that a given set of laser operations will cause a transformation that depends not just on their order, but also on the system's starting point.

“It is like finding the precession of a Foucault's pendulum to be different if you start the measurement at 9am as opposed to 4pm. This is a genuine quantum effect without any classical counterpart,” explains David. The Earth's constant rotation means a Foucault pendulum has a fixed rate of precession.

In the group's setup, the strontium atoms are first cooled to a temperature about one millionth of a degree above absolute zero, around -273°C. The researchers then turn on a trio of red lasers that interact with some of the atoms' internal energy states.

“Everything comes from a precise external control of the relative phases of the lasers,” explains David. The team arrange the atoms to behave like they each have just two quantum states, which are linear combinations of their original ground states. The system is then equivalent to an ensemble of spin-1/2 particles, for which the spin can be rotated without any cost of energy.

The team monitored the spins as they changed the phase of the lasers, confirming that the transformations had non-Abelian character. Other atoms would also show this effect if they have comparable energy level structures.

An interesting outcome is that the atoms change their spin orientation as they move a distance comparable to the wavelength of the laser, just a few hundred nanometers.
This gives a method to measure temperature, by revealing the speed velocity distribution of the atomic cloud. The team needed just tens of microseconds to determine the cloud's temperature – up to a thousand times faster than a conventional approach.
This thermometric method is promising to measure ultra-low temperatures or position-momentum correlation where conventional methods are less sensitive or don't work.

Future directions

“This is only the beginning of the story. Many fascinating experiments and applications are within our reach,” says David. He did the work with team members Frederic Leroux, Kanhaiya Pandey and Riadh Rebhi, now alumni, along with Christian Miniatura, Benoit Gremaud and collaborator Frederic Chevy at the Laboratoire Kastler Brossel in Paris. Many of the group are also members of the MajuLab, a joint research unit of French and Singaporean partners.

In particular, the scheme offers a way to simulate ‘gauge field' structures such as two-dimensional spin-orbit coupling, relativistic trembling motion (Zitterbewegung) and magnetic monopoles. To observe those phenomena, the strontium gas needs to be further cooled to bring the temperature to around 10 trillionths of a degree. The team is working to achieve this.

In recent years, other research teams have achieved a slew of results simulating materials in cold atoms trapped in optical lattices. In this approach, the gauge field can only take discrete values relating to the hopping of atoms between lattice sites. David's group does not use a lattice, allowing continuous tuning of the effective gauge field. This will give more flexibility in designing simulations.
