From the
head of department
Last week’s big event took place on Thursday when rector declared SFF
Birkeland Centre for Space Science open – followed
by several enthusiastic lectures on scientific research in the centre. We invite all the employees and students to the
White Laday and Champagne in order to celebrate the
opening of the centre in advance of Friday’s
exciting open seminar on space physics. We can look forward to hear more on
scientific research in the centre at the open
seminars to take place throughout the year. Have a nice weekend, News and general
information
IFT
open seminar March 8 – celebrating the opening of the Birkeland
Center
On Friday, March 8, we replace ethe usual
pastries with the White Lady cake, and the usual coffee with Champagne, and
invite you all to the open seminar with Dr. MargaTret
W. Chen , Space Sciences Department , The Aerospace Corporation, USA –
also a member of scientific advisory board in Birkelandsenteret: ·
Dynamics of the Earth Ring Current: Recent Understanding through
Self-Consistent Simulations Friday, March 8,
at 14:15, Auditorium B. Coffee, White Lady
cake and Champagne from 14:00. The ring current consists of oppositely drifting ions and electrons
with energies of ~ 10 to 200 keV in the same region
of the Earth’s magnetosphere that the radiation belts occupy. During
geomagnetic storms, these particle populations at ring current energies are
significantly increased. Associated
with the storm-time ring current is a perturbation magnetic field that
distorts the inner magnetospheric magnetic field,
thereby affecting radiation-belt dynamics. In this seminar I will first briefly
discuss early idealizations of ring current formation and then focus on
recent advances in understanding ring current dynamics using more realistic
self-consistent guiding-center drift and loss
simulations. A magnetically and electrically self-consistent treatment of
particle transport tends to limit the formation of the ring current as
compared to simpler treatments. The
ring current intensity and spatial distribution are also significantly
affected by variations in the plasma sheet, the major source to the ring
current. I will show comparisons of
in-situ magnetic field and plasma data and energetic neutral atom (ENA)
intensity with corresponding quantities from our self-consistent ring current
simulation model during storm events.
Such comparisons test the ability of our model to characterize the
ring current plasma environment and magnetic field and challenge further our
understanding of ring current dynamics. IFT
open seminar next friday
All are welcome to an open seminar where Sabrine Hossenfelder, Nordita, will hold the following lecture: ·
News
from Quantum Gravity Phenomenology Friday, March 15,
at 14:15, Auditorium B. Coffee, tea and cake
from 14:00. The talk will be on recent developments in the search for
experimental signatures for quantum gravitational effects. Some of the topics
that will be covered are the prospects of finding Planck scale effects in
gamma ray bursts, in neutral Kaon oscillations, or
with massive quantum oscillators. Further, the prospect of finding
holographic noise and on Bekenstein's proposed
table top experiment will be commented. This is not a review talk; it is a
hand selected assortment of interesting topics. Master Week 2013
In week 11, the Faculty of Mathematics and
Natural Sciences arranges Master Week
2013. The aim is to present the scope of the
various master programmes and which possibilities
students have after completing their bachelor degree. All interested students
and employees are invited to the informative meetings for the various master programmes. At IFT, we arrange the following meetings at
room 359, Allégaten 55 "bachelor room": ·
Petroleum Technology – Tuesday, March 12, 10:15-12:00 ·
Physics – Wednesday, March
13, 10:15-12:00 ·
Process Technology – Thursday, March
14, 14:15-16:00 In addition, we also arrange informative
meetings for several relevant master programs at other departments. Lecture
during the Master Week
All interested in natural sciences, education and teaching, are
invited to a lecture with Håvard Tjora, known from
the TV-program "Blanke ark" (Blank Pages): ·
"Mathematics
Around us – Bringing Mathematics to Life" Friday, March 15,
at 13:00, Auditorium Pi, Autogården, Johannes Bruns gate
12. The lecture is meant to inspire and motivate students and employees
for the teaching profession. Trainee
Vest: 16 trainee positions in the Bergen region
All master
students should take a look at this year’s Trainee-vest
positions. Applications deadline is March 20. STAFF
We have the pleasure of wishing two new
colleagues a warm welcome to our department: Bachelor
h-bar
On Tuesdays, every even-numbered week, there are pub lectures taking
place at the H-bar. More info at H-bar’s facebook page. H-bar is run by department’s Fagutvalget,
and is primarily aimed at department’s students – but employees are also
welcome! IFT iN the media
