Dear colleagues, dear members of the Association MaNEP,

I hope that you and your families are well in these exceptional times. The coronavirus pandemic is creating a strong and lasting effect on every one of our private and our world-wide professional activities, and the Association MaNEP is no exception. However, there is a glimmer of hope that, for most institutions in Switzerland, we may resume regular, on-site research during the summer, and in autumn also our teaching activities.
The MaNEP steering committee, in full consultation with the programme and organising committees, decided to cancel this year’s SWM conference in Les Diablerets, which was scheduled for the very end of August. We now plan that this conference will go ahead in August 2021 with an updated programme. For the time being, the MaNEP Winter School remains on schedule for January 2021, and indeed registration will open very soon.

In times of crisis, we as physicists are motivated to think beyond the usual boundaries of our discipline. Many times in the past we have been able to apply methods and elements of technology, which were developed primarily for experimental or theoretical physics, to problems outside our areas of research. NMR/MRI and gene sequencing are prominent, high-impact examples in medicine and biomedical research. Successful translations often require an interdisciplinary setting, combining in some cases the most fundamental spectroscopic techniques, or methods from statistical physics, with expertise in virology and epidemiology. Gabriel Aeppli from the Paul Scherrer Institute shows some recent examples from COVID research in his scientific perspective, and together with other colleagues has proposed methods for efficient testing (https://arxiv.org/abs/2004.04614). Please keep your eyes open and your minds active well beyond condensed-matter boundaries – a message especially relevant for times like the COVID pandemic, but also broadly true for all the activities and skills of the Association MaNEP.

Scientific perspective

What can quantum many-body physics and optics bring to virology?

Perspective
By Prof. Gabriel Aeppli, Paul Scherrer Institut
Among the most important problems illuminated by the current COVID-19 pandemic are those of producing and measuring the immune response to the corona virus. The immune response defines the progression and lethality of the disease in an infected individual, while the idea of promoting such a response through a harmless trigger molecule or viral-like complex is at the core of vaccine development. A key challenge for both patient care as well as research is thus the metrology of the immune response.

Low-energy excitations in type-II Weyl semimetal Td-MoTe2 evidenced through optical conductivity

Ana Akrap figure
By Ana Akrap, University of Fribourg
Transition metal dichalcogenides are a rich and diverse family of compounds. In both bulk and few-layer form, transition metal dichalcogenides are intensely studied for many of their interesting properties: excitons, superconductivity, and band-gap tuning by thickness. They are also pursued for ...
