QTeQ’s work in PRL as an Editors’ Suggestion

QTeQ strikes an Editors’ Suggestion for their latest paper in Phys. Rev. Lett.!!!

As a result of an international collaboration (involving ETH Zurich, the University of Vienna, the University of Sao Paulo, Universidade Federal do ABC, Chalmers, and the University of Cambridge), Alessandro, Gabriele and Mauro have published a paper in Phys. Rev. Lett. reporting on the assessment of entropy production from non-equilibrium quantum processes realised in an optomechanical system and an intra-cavity BEC one. The paper puts in place a theoretical framework for the observation of entropy production in Gaussian states developed as a result of the Sao Paulo–Belfast all-theory collaboration and embodies the first observation of entropy production in non-equilibrium mesoscopic quantum systems. Huge work done by former QTeQers Matteo Brunelli and Lorenzo Fusco, who worked hard to see these results published. Well done guys!!!

The details of the paper can be found here

QTeQ awarded Leverhulme Trust Grant!

QTeQ has been awarded a Leverhulme Trust Research Project Grant to investigate thermodynamics of quantum systems and the construction of a single-atom quantum engine using optical tweezers and quantum control techniques. The project, called UltraQuTe, is a collaboration with the Birmingham-based experimental group led by Dr. Giovanni Barontini, an expert in the manipulation of the quantum state of ultra-cold atoms and an enthusiast of quantum thermodynamics. A new member of QtEQ will join the group in November!!

QTeQ on retreat!!!

The 2018 QTeQ retreat kicked off this morning with the welcome by one of the organisers, Helena Majury, and a talk by Ricardo Puebla on quantum simulation! The programme continues with Andre’ talking of quantum gravity, Oussama discussing of state-engineering in optomechanics, and Obinna illustating his quantum thermodynamic results.

The group will get together for two days, benefiting of the input by visitors Matteo Carlesso and Alessio Belenchia, both presenting as friends-of-the-family and future members of the team (Alessio).

The organisers, Helena Majury, Christine Cartwright, and Hannah McAleese, have put together a programme of scientific talks, poster presentations, and group activities aimed at informing the group of all the different research strands within QTeQ, and strengthening the ties among its members.

Many thanks to Christine, Hannah and Helena

A whole bunch of new QTeQ members

New members have joined the group in the last few months!

Dr. Ricardo Puebla Antunes has joined us from the University of Ulm to work under DfE-SFI funding on problems of open-system dynamics aimed at describing the evolution of small quantum systems under the presence of complex environments. This will be relevant to the group’s endeavours in understanding the physics of single-photon emitters in solid state.

Mr. Giorgio Zicari joined us under the framework of the MSCA Cofund project SPARK to work on the possible benefits of a machine-learning approach to one-system dynamics. Giorgio previously worked at University of Bari, under the supervision of Prof. S. Pascazio, and at ICTP Trieste, working with Prof. A. Scardicchio.

Miss Marta Marchese secured a PhD position within the group under the funding provided by the H2020 Collaborative Project TEQ to work on the test, in mesoscopic physics, of alternative models to standard decoherence theory. Marta received her degrees from the University of Palermo and the University of Trieste, where she worked under the supervision of Prof. A. Bassi.

Welcome to everybody and have fun!

..and congrats to Dr. Ruari McCloskey as well!!

Congratulations to Ruari McCloskey, who passed his PhD Viva today!!
Ruari successfully defended his thesis against the ‘attacks’ by Dr. Andrew Brown (CTAMOP, Queen’s) and Prof. Bassano Vacchini (University of Milan). QTeQ congratulates Ruari on becoming a Dr. and hope to see him around as often as possible, although we are all aware he will be very busy becoming a super-star with his band (Civil Simian: check them out!!) and, as a hobby, working as a data analyst.

Congratulations to Dr. Brunelli

The whole QTeQ congratulates Matteo Brunelli for adding the prefix Dr. to his name!

On Monday 28 August 2017, our own Matteo has brilliantly passed his PhD viva with only minor corrections to his otherwise brilliantly written dissertation. The external examiner, Prof. Klemens Hammerer (Hannover) was very positively impressed by Matteo’s critical attitude to his own work and the depth of his understanding of non-equilibrium thermodynamics of quantum processes in harmonic systems.

Matteo will (sadly for us!) soon leave Belfast to join the group led by Dr. Andreas Nunnenkamp in Cambridge. He will be deeply missed, but we hope for frequent and extensive visits to ‘home’.

Feodor Lynen Fellow joins QTeQ

Great news for QTeQ: Dr. Andre’ Grossardt, an expert of foundations of quantum mechanics and, in particular, the Newton-Schroedinger equation and dynamics, has been awarded a Feodor Lyen Fellowship of the Alexander von Humboldt Foundation to join QTeQ for two years.

Andre’ will be hosted by Mauro (a former von Humboldt Fellow) to further his studies on the foundation of quantum theory, this time making use of the tools made available by an information theoretic approach.

The Feodor Lynen Fellowship is a very prestigious fellowship from the Alexander von Humboldt Stiftung, aimed at strengthening the link with von Humboldt Alumni and excellent German scholars. This is only the latest success of the group in attracting highly sought after fellowship, and pairs with Obinna Abah’s recent one-two success with the 1851 Fellowship and the Royal Society Newton Fellowship.

QTeQ is humbled to have been chosen and delighted to host Andre’ for the next 24 months. Andre’ will join the ‘post-doc team’ of the group, consisting of Oussama, Obinna, and Matteo. We have a truly international team, guys!!!

QTeQ winter annual retreat

It’s that time of the year again! The group has just started its annual winter retreat to make the point of what our research was about over the past year, welcome the new members of the team (this year Adam and Qiongyuan), and hear from our visitors (this time we have Baris Cakmak from Koc University Istanbul).

QTeQ is currently meeting in the beautiful Graduate School at Queen’s University Belfast, enjoying a full day of talks and a party afterwards! New group photo coming up soon…

Congratulations to Lorenzo!!

QTeQ congratulates Lorenzo Fusco on successfully passing his PhD viva!!!
Lorenzo has brilliantly defended his thesis, titled “Non-equilibrium thermodynamics
in quantum many-body systems” before the committee formed by Dr. Gleb Gribakin (QUB) and
Prof. Eric Lutz (Erlangen Universitaet).

Gabriele, Mauro and the whole group are proud of Dr. Lorenzo!
