I am a theoretical physicist working at the
University of Surrey. Surf the upper panel
to find information about who I am and the
research I carry on. Enjoy your visit! Students or post-docs interested in carrying out a research
project on theoretical nuclear physics and
looking for funding opportunities,
Nuclear spectral functions and chiral forces
Spectral functions characterise the properties of
nucleons in dense matter. They provide a
unique insight into nuclear correlations and can be
used to access both thermodynamical and structural properties. We have
found a way to characterise spectral functions and
provide a link to chiral nuclear hamiltonians by looking
at the size and shape of the spectral function's
standard deviations. All explained in more detail in
Here's the talk that I gave at the
Event "Redifining the Ordinary" on 27
February 2016. I hope you enjoy it!
Di-neutrons? Yes, please
Di-neutrons are loosely bound states of two
neutrons. They do not exist in free-space, but they
can appear in dense nuclear media. In a
collaboration with Felipe Isaule (who visited Surrey
for a month on Jan 2015) and Prof.
Hugo Arellano, we
report on the first microscopic results on the
structure of di-neutrons in neutron matter.
Fission paper out
My second paper on nuclear fission,
with results from Phil Goddard's thesis and in
collaboration with Paul Stevenson,
has now been published here. Have a look to see what you can do with
3D TDHF and boosts!
Rosh Sellahewa becomes a doctor
(co-supervised with Jim Al-Khalili) has
successfully held his thesis viva today. His work on
neutron star physics and the Gogny interaction has
been published here. And there are
more papers to come, even though Rosh has moved on
to pastures new. Congratulations Rosh!
This website has been on a standstill during my
paternity leave on the summer of 2015 - but I am
back to work!
I have decided to dub this week "Fission week":
my first paper on fission has been accepted for
publication in Phys. Rev. C, and the second one is
out now as a preprint. All
these results were cooked up by Phil Goddard, a
former PhD student that now does more useful stuff!
Pairing gap and correlations
The pairing gap in high-density neutron matter is
sensite to short- and long-range
correlations. Some new results on these effects are
presented in a preprint, written with collaborators at
Washington University in St. Louis.
Phil Goddard becomes a doctor
Arnau's second PhD student, Phil Goddard,
(co-supervised with Paul Stevenson) has
successfully held his thesis viva today. Congratulations Phil!
Gogny forces and neutron stars
The first paper from Rosh Sellahewa's PhD is now
out. Check it out if you are interested on Gogny
forces or neutron stars! It's here.
Propagating errors at finite T
Arnau's first paper with Xavier
Roca-Maza looks at error propagation in "hot" density
functional theory. Have a look at it here.
Arianna Carbone becomes a doctor
Arnau's first PhD student, Arianna Carbone,
(co-supervised with Artur Polls) has
successfully defended her thesis. Feel free to have a look at it here.
Creative Commons Paper
Arnau first open access (CC licence)
paper has been published today.

High-momentum components in nuclear matter
Arnau has submitted a paper on the density and
isospin asymmetry dependence of short-range
correlations. It has implications for electron
scattering experiments. Check it
Arnau is organizing a
