“D-branes in AdS_3 x S^3 x T^4 at k = 1 and their holographic duals”

Abstract: Following the recent work of Eberhardt, Gaberdiel and Gopakumar, exact comparison between various quantities living on the two sides of the AdS/CFT duality has become a possibility. The goal of this talk will be to extend the existing holographic dictionary to include some non-perturbative vacua on both sides. I will start by reviewing the original, purely closed-string setup, giving arguments that string theory on AdS_3 x S^3 x T^4 with minimal k=1 NS-NS flux is exactly dual to the symmetric-product orbifold CFT with the T^4 as the seed. I will then construct various D-branes of this string theory and calculate their associated cylinder amplitudes. We will observe that these amplitudes match with the cylinder correlators of certain boundary states of the dual CFT, thus suggesting a direct correspondence between these boundary conditions. I will also show that the disk amplitudes of these D-branes localise to those points in the worldsheet moduli space where the worldsheet disk holomorphically covers the spacetime disk. This talk is based on https://arxiv.org/abs/2110.05509.

“Probing specific crystal lattice sites with X-ray standing waves ”

Abstract:  The crystal structure of magnetite (Fe3O4) involves Fe2+ ions in sites with octahedral (Oh) symmetry and Fe2+ and Fe3+ ions in sites with tetrahedral (Td) symmetry. Magnetite exhibits several interesting physical phenomena that are not yet fully understood, such as the Verwey transition, in which the roles of the different Fe sites are an active subject of research. The X-ray standing wave (XSW) technique uses the combination of an incoming and a Bragg reflected X-ray beam to create a standing X-ray wave inside the crystal. The nodes and antinodes of the radiation field can be tuned to different crystallographic planes. In the dipole approximation, the absorption cross section is proportional to the intensity of the X-ray field, while for quadrupolar terms, it’s proportional to the field’s gradient. Changing the phase of the radiation field thus allows us to selectively vary the contributions of different atoms and absorption types (dipolar vs quadrupolar) to the total absorption spectrum. This will aid in studying the elusive physical properties of magnetite in a site-selective manner.

Duration of fellowship: 3–12 months, visits 3–6 months


Magnus Ehrnrooth Foundation

Post doc scholarships

Persons who recently have obtained their PhD may apply for a postdoctoral scholarship. The purpose of a postdoctoral scholarship is to enable the grantee to further develop as a researcher. Applicants for a postdoctoral scholarship may also apply for support for research related costs and travel. A separate application for these purposes must be made.

Graduate student scholarships

The graduate student stipend can be awarded for a period of one year or a half year, preferably for the period 1.7. – 31.12. to a student who has been accepted by the university as a doctoral student. The stipend can be awarded conditionally to a student about to graduate.


The Runar Bäckström Foundation

The aim of the Runar Bäckström foundation is to encourage and support inventions that are beneficial to Finnish businesses and thereby strengthen their global competitiveness. The foundation assigns grants once a year. Individuals, work groups, companies or associations can apply for the grants.

Application period: The application period is open from 1 October to 15 December 2021.
