Saga Helgadottir will give a presentation at the Gothenburg Science Festival 2020.
The International Science Festival Gothenburg is one of Europe’s leading popular science events. Its first edition dates back to 1997, and it is held every year in spring.
This year the festival will take place during autumn, 28 September-4 October. Due to the current situation the festival will be a digital event. The digital festival will be available during the week of the festival.
The contribution of Saga Helgadottir will be presented according to the following schedule:
Saga Helgadottir Deep Learning for Object Recognition
Deep Learning is a machine learning technique that teaches computers to do what comes naturally to humans: learn by example. In this talk, I will show how Deep Learning can be used to identify objects in images, in particular microscopic particles.
Giovanni Volpe will give an online invited presentation at the Student Conference on Optics and Photonics (SCOP), organized by the OSA student chapter of Physical Research Laboratory, Ahmedabad, India.
The conference addresses various topics in optics with an emphasis on non linear optics and quantum optics, will be held during 23-25 September, 2020 at the Physical Research Laboratory (PRL), Ahmedabad, India.
The conference includes invited talks by eminent scientists from India and abroad, as well as posters and oral presentations by student participants and research fellows.
The contribution of Giovanni Volpe will be presented according to the following schedule:

The OSA Chapter of Gothenburg together with the Association of Graduate Students in Physics (FFF) will organise an online career talk by Aura Higuera Rodriguez, OSA ambassador and Technical Account Manager at Synopsys Photonic Solutions. The seminar will take place online via Zoom on Tuesday 6th of October at 5 pm.
Aura completed her PhD at Eindhoven University of Technology in the photonic integration group. Afterwards, she worked at the Photonic Integration Technology Center as JePPIX Coordinator and Application Support and since January 2019 she joined Synopsys Photonic Solutions as Technical Account Manager. More about Aura on the OSA website .
Aura is among the OSA Ambassadors 2020 and her talk will focus on Career Development and Emotional Intelligence. The seminar is open to all members of the University of Gothenburg and Chalmers University of Technology via registration using the institutional email.
A new student chapter of the Optical Society of America (OSA) has been established at the Physics Department of Gothenburg University!
The founding members of the GU-OSA student chapter are students from the Soft Matter Lab, the Biophysics Group, and Optical Levitation Group, all part of the Physics Department of Gothenburg University. The chapter activity started on the autumn semester of 2020 with the online kick-off meeting, where the future plans and activities of the GU-OSA chapter were discussed.
The Optical Society of America (OSA) supports outreach and networking through the student chapters. So far, there are over 370 Student Chapter across the world organising events such as seminars, colloquiums, and outreach activities focused on increasing awareness of the importance of optics in our daily life and society.
Non-equilibrium Properties of an Active Nanoparticle in a Harmonic Potential
Falko Schmidt, Hana Šípovà-Jungová, Mikael Käll, Alois Würger & Giovanni Volpe
Active particles break out of thermodynamic equilibrium thanks to their directed motion, which leads to complex and interesting behaviors in the presence of confining potentials. When dealing with active nanoparticles, however, the overwhelming presence of rotational diffusion hinders directed motion, leading to an increase of their effective temperature, but otherwise masking the effects of self-propulsion. Here, we demonstrate an experimental system where an active nanoparticle immersed in a critical solution and held in an optical harmonic potential features far-from-equilibrium behavior beyond an increase of its effective temperature. When increasing the laser power, we observe a cross-over from a Boltzmann distribution to a non-equilibrium state, where the particle performs fast orbital rotations about the beam axis. These findings are rationalized by solving the Fokker-Planck equation for the particle’s position and orientation in terms of a moment expansion. The proposed self-propulsion mechanism results from the particle’s non-sphericity and the lower critical point of the solute.
The School of Nano Science, IPM, Tehran, Iran, with the support of IASBS, Zanjan, Iran, is organizing a one-day e-workshop on Novel Features and Applications of Optical Manipulation
on September 8th, 2020.
The workshop will address the latest features of optical manipulation. Distinguished lecturers in the field will present exciting aspects and applications of optical manipulation along with providing educational outreach to students.
The workshop is open to all and it is free, but pre-registration is required. Registration dates: between 10 and 25 August.
