α clustering in ²⁸Si probed through the identification of highlying 0⁺ states
(American Physical Society, 2017)Background: Aspects of the nuclear structure of light αconjugate nuclei have long been associated with nuclear clustering based on α particles and heavier αconjugate systems such as ¹²C and ¹⁶O. Such structures are ... 
Vacuum polarization energy for general backgrounds in one space dimension
(Elsevier, 2017)For field theories in one time and one space dimensions we propose an efficient method to compute the vacuum polarization energy of static field configurations that do not allow a decomposition into symmetric and antisymmetric ... 
Universal equilibrium scaling functions at short times after a quench
(American Physical Society, 2017)By analyzing spinspin correlation functions at relatively short distances,we showthat equilibrium nearcritical properties can be extracted at short times after quenches into the vicinity of a quantum critical point. The ... 
Superfluid filaments of dipolar bosons in free space
(American Physical Society, 2017)We systematically investigate the zero temperature phase diagram of bosons interacting via dipolar interactions in three dimensions in free space via path integral Monte Carlo simulations with a few hundreds of particles ... 
Solving Dirac equations on a 3D lattice with inverse Hamiltonian and spectral methods
(American Physical Society, 2017)A new method to solve the Dirac equation on a 3D lattice is proposed, in which the variational collapse problem is avoided by the inverse Hamiltonian method and the fermion doubling problem is avoided by performing spatial ... 
Selfconsistent relativistic quasiparticle randomphase approximation and its applications to chargeexchange excitations
(American Physical Society, 2017)The selfconsistent quasiparticle randomphase approximation (QRPA) approach is formulated in the canonical singlenucleon basis of the relativistic Hatree–Fock–Bogoliubov (RHFB) theory. This approach is applied to study ... 
Search for highly excited states in ²⁸Si
(IOP Publishing, 2017)The theoretical and experimental determination of superdeformed states in nuclei in the mass region A≤40 has been since a long time one of the major challenges of nuclear structure studies. Despite the considerable ... 
Scattering in a threedimensional fuzzy space
(American Physical Society, 2017)We develop scattering theory in a noncommutative space defined by an su(2) coordinate algebra. By introducing a positive operator valued measure as a replacement for strong position measurements, we are able to derive ... 
Quantum stabilization of a hedgehog type of cosmic string
(Elsevier, 2017)Within a slightly simplified version of the electroweak standard model we investigate the stabilization of cosmic strings by fermion quantum fluctuations. Previous studies of quantum energies considered variants of the ... 
Quantum effects in the cooperative scattering of light by atomic clouds
(American Physical Society, 2017)Scattering of classical light by atomic clouds induces photonmediated effective longrange interactions between the atoms and leads to cooperative effects even at low atomic densities. We introduce a simulation technique ... 
PTsymmetric waveguide system with evidence of a thirdorder exceptional point
(American Physical Society, 2017)An experimental setup of three coupled PT symmetric waveguides showing the characteristics of a thirdorder exceptional point (EP3) has been investigated by Heiss and Wunner in an idealized model of three δfunction waveguides ... 
Prethermalization and persistent order in the absence of a thermal phase transition
(American Physical Society, 2017)We numerically study the dynamics after a parameter quench in the onedimensional transversefield Ising model with longrange interactions (∝1/rα with distance r), for finite chains and also directly in the thermodynamic ... 
A pilot study investigating the presence of voids in bulk fill flowable composites
(South African Dental Association, 2017)OBJECTIVE: To investigate the presence of voids in bulk fill flowable composites. METHODS: This study investigated two wellknown bulkfill flowable composites, Smart Dentin Replacement (SDR) (Dentsply/Caulk, Milford, ... 
Phases of dipolar bosons in a bilayer geometry
(American Physical Society, 2017)We study, by firstprinciples computer simulations, the lowtemperature phase diagram of bosonic dipolar gases in a bilayer geometry as a function of the two control parameters, i.e., the inplane density and the ... 
Nuclear matter properties with nucleonnucleon forces up to fifth order in the chiral expansion
(American Physical Society, 2017)The properties of nuclear matter are studied using stateoftheart nucleonnucleon forces up to fifth order in chiral effective field theory. The equations of state of symmetric nuclear matter and pure neutron matter are ... 
Nuclear matrix element of neutrinoless doubleβ decay : relativity and shortrange correlations
(American Physical Society, 2017)Background:The discovery of neutrinoless doubleβ (0νββ) decay would demonstrate the nature of neutrinos, have profound implications for our understanding of matterantimatter mystery, and solve the mass hierarchy problem ... 
Noninvasive measurement of dynamic correlation functions
(American Physical Society, 2017)The measurement of dynamic correlation functions of quantum systems is complicated by measurement backaction. To facilitate such measurements we introduce a protocol, based on weak ancillasystem couplings, that is ...
