German Research Foundation supports new theoretical physics project at Jacobs University Bremen

18.12.2018

The research project, led by Dr. Stefan Kettemann, Professor of Complex Systems, aims at solving the fundamental problem of thermodynamics and dynamics of disordered quantum spin systems with long-range interactions. It is funded by the German Research Foundation for three years with 203,400 EUR. Talented young scientists can apply for the PhD position to be filled.

The aim of this project is the systematic investigation of the thermodynamic and dynamic properties of disordered systems with local quantum degrees of freedom, such as spins or tunnel systems with long-range interactions.


Circuits of a quantum computer

Such systems exist in many materials, such as metals with magnetic impurities or doped semiconductors and glasses.

Donor spins are investigated as qubits for quantum computers. The coherent control and reading of the qubits, however, requires a detailed understanding of the thermodynamic and dynamic properties of such systems.

The combination of disorder and long-range interaction makes this a challenging fundamental problem of theoretical physics.

Accordingly, this problem requires a combination of approaches such as modifications of the spatial renormalization group method and a tensor network extension of the density matrix renormalization group method.

Led by Prof. Kettemann and in close collaboration with research groups at Princeton University, the University of Southern California and Tokyo University, this project gives a talented PhD student the opportunity to work on this fundamental problem for three years.

Applications for the PhD position should include all application documents:
