To which densities is spin-polarized neutron matter a weakly interacting Fermi gas?
Abstract We study the properties of spin-polarized neutron matter at next-to-next-to-next-to-leading order in chiral effective field theory, including two-, three-, and four-neutron interactions. The energy of spin-polarized neutrons is remarkably...

A non-trivial zero length limit of the Nambu–Goto string
Abstract We show that a Nambu–Goto string has a nontrivial zero length limit which corresponds to a massless particle with extrinsic curvature. The system has the set of six first class constraints, which restrict the phase space variables so that...

Lagrangian formulation of massive fermionic higher spin fields on a constant electromagnetic background
Abstract We consider massive half-integer higher spin fields coupled to an external constant electromagnetic field in flat space of an arbitrary dimension and construct a gauge invariant Lagrangian in the linear approximation in the external field....

Analog geometry in an expanding fluid from AdS/CFT perspective
Abstract The dynamics of an expanding hadron fluid at temperatures below the chiral transition is studied in the framework of AdS/CFT correspondence. We establish a correspondence between the asymptotic AdS geometry in the 4 ...

Integrable properties of σ-models with non-symmetric target spaces
Abstract It is well known that σ-models with symmetric target spaces are classically integrable. With the example of the model with target space the flag manifold U ...

Spectrum imaging of complex nanostructures using DualEELS: I. digital extraction replicas
Abstract This paper shows how it is possible to use Dual Electron Energy Loss Spectroscopy (DualEELS) to digitally extract spectrum images for one phase of interest in a complex nanostructured specimen. The specific cases studied here concern Nb or...

Detection of solar neutron events and their theoretical approach
Abstract Solar neutron events provide important opportunities to explore particle acceleration mechanisms using data from ground-based detectors and spacecrafts. Energetic neutrons carry crucial physics information of the acceleration site, such as...

Metastable vacuum decay and θ dependence in gauge theory. Deformed QCD as a toy model
Abstract We study a number of different ingredients related to the θ dependence, metastable excited vacuum states and other related subjects using a simplified version of QCD, the so-called “deformed QCD”. This model is a weakly coupled gauge...

Momentum Transfer in Hypervelocity Impact Experiments on Rock Targets
Abstract A special phenomenon observed in hypervelocity impacts on rock targets is the so-called momentum multiplication, i.e. the momentum transferred to the target is greater than the original momentum of the projectile. This effect is caused by...

“Bi-modal” isoscalar giant dipole strength in 58Ni
Abstract The strength distribution of the isoscalar giant dipole resonance (ISGDR) in 58Ni has been obtained over the energy range 10.5–49.5 MeV via extreme forward angle scattering (including 0°) of 386 MeV α particles. We observe a “bi-modal” E1...

Noncommutative fermions and Morita equivalence
Abstract We study the Morita equivalence for fermion theories on noncommutative two-tori. For rational values of the θ parameter (in appropriate units) we show the equivalence between an abelian noncommutative fermion theory and a nonabelian theory...
