2025

Welcome to our annual Christmas seminar! After the seminar, we'll continue with dinner in our wonderful facilities.

For invited people. 

Joakim Bergli:  

Quantum synchronization is often studied using a master equation, typically the Lindblad equation. This gives the time evolution of the density matrix. If we study the response to a periodic external signal, synchronization is detected by a steady state density matrix that is in phase with the external signal. 

Viktor Svensson:  

Majorana bound states are quasiparticles which could be used to make qubits protected from noise. This protection relies on the spatial separation between Majoranas. These statements make sense in non-interacting theories, where quasiparticles and their location can be defined, but how can one generalize this to interacting systems? 

Zhao Zhang: We show that the ground states of the singly hole-doped Infinite-U Hubbard model on one- and infinite-dimensional lattices of corner-sharing tetrahedra doped are partially dimerized resonant valence bond states.

Vytautas Zalandauskas: First-principles density functional theory calculations as a valuable tool for determining the chemical origin of point defects and characterizing their various properties.

Cecilie Glittum:

The groundbreaking ideas of the resonant valence bond (RVB) liquid initiated a transformative shift in modern physics. Extensive implications influenced a broad spectrum of fields, from high-temperature superconductors to quantum computing, and gave birth to key concepts in physics, such as quantum spin liquids, emergent gauge symmetries, topological order, and fractionalisation. Despite extensive efforts to demonstrate the existence of an RVB phase, a definitive realisation has proven elusive.

Morten Hiorth-Jensen:

In two series of seminars (in a more journal-club style) I will present two recently developed physics-inspired algorithms with potential applications to quantum computing.

Juan David Alvarez Cuartas:

Modern challenges in energy storage demand new paradigms beyond classical technologies. Quantum batteries (QBs) exploit coherence, superposition, and entanglement to enhance storage capacity and enable ultrafast charging, with recent work identifying superabsorption as a key mechanism.

David Jansen from ICFO:

In this talk, I will demonstrate how relaxations with semidefinite programs (SDPs) can be used to map out ground-state phase diagrams for quantum spin systems in one and two dimensions—a critical problem in condensed matter physics. 

Fiday this week, Tamás Havas & Olai Mostad, PhD students at Simula UiB, will tell us about quantum communication and error correction.

Thursday this week, Anna Birk Hellens from the Johannes Gutenberg Universität Mainz, will give a talk on altermagnets, a subject they have helped pioneer.

Elin Melby and Ellen Kleveland from Veksthuset and Inven2 will give a presentation on how to move from ideas and research to reality. 

Corinne Manogue - Oregon State University:
In this interactive workshop, we will share some classroom activities that were developed in the Paradigms in Physics Program at Oregon State University for use in an upper-level, undergraduate physics course on quantum mechanics at the level of McIntyre: Quantum Mechanics. 

This week, Wojciech Jankowski from the University of Cambridge will tell us about his work on topological and geometrical effects in quantum matter.

This week, Francesco Pietro Massel from USN will tell us about the use of using mechanical oscillators coupled to qubits for quantum technology: 

This week, Maxim Kartamyshev from Norges Bank Investment Management ("Oljefondet") will tell us about the use of Quantum Technology in Finance:

This week, Kristian Wold will tell us about quantum chaos. Kristian is a PhD candidate at OsloMet: 

This week, Shaukat Ali will tell us about quantum extreme learning machines. Shaukat is a Chief Research Scientist at Simula, where he works on various aspects of quantum software engineering: 

This week, Alexander Müller-Hermes will tell us about quantum information theory. Alexander is an associate professor at UiO, and is also part of  the QOMBINE project:

This week, Franz Georg Fuchs, senior research scientist at Sintef and leader of the Gemini Center on Quantum Technology will tell us about his recent research. 

This week's seminar will be a journal club given by Morten Hjorth-Jensen and yours truly, discussing the paper which came up last week:

Experimental critical quantum metrology with the Heisenberg scaling

This week's speaker is Morten Hjorth-Jensen. Morten is a physics professor at UiO, and has worked on a wide range of topics within quantum science and technology.
