Magnetic field induced tunability of spin Hamiltonians: Resonances and Efimov states in Yb_{2}Ti_{2}O_{7}

open access: yesPhysical Review Research, 2020
Universality is a powerful concept that arises from the divergence of a characteristic length scale. For condensed matter systems, this length scale is typically the correlation length, which diverges at critical points separating two different phases ...

Anatomy of three-body decay III. Energy distributions

open access: yes, 2005
We address the problem of calculating momentum distributions of particles emerging from the three-body decay of a many-body resonance. We show that these distributions are determined by the asymptotics of the coordinate-space complex-energy wave-function

Berry Phase Coupling and the Cuprate Neutron Scattering Resonance [PDF]

open access: yesarXiv, 2009
We examine the influence of coupling between particle-hole and particle-particle spin fluctuations on the inelastic neutron scattering resonance (INSR) in cuprate superconductors in both weak and strong interaction limits. For weak-interactions in the particle-hole channel, we find that the interchannel coupling can eliminate the resonance.

Exploring the potential of resonance islands and bent crystals for a slow extraction from circular hadron accelerators

open access: yesPhysical Review Research
New developments in accelerator physics have broadened the set of available techniques for manipulating charged-particle beams. Adiabatic trapping and transport of a beam in resonance islands has been studied and successfully implemented at the CERN ...

Dalitz plot analysis of the D + → K − K + K + decay

open access: yesJournal of High Energy Physics, 2019
The resonant structure of the doubly Cabibbo-suppressed decay D +→K − K + K + is studied for the first time. The measurement is based on a sample of pp-collision data, collected at a centre-of-mass energy of 8 TeV with the LHCb detector and corresponding

Mechanism of Pion Production in $alpha$p Scattering at 1 GeV/nucleon

open access: yes, 2011
The one-pion and two-pion production in the p(alpha, alpha prime)X reaction at an energy of E{alpha} = 4.2 GeV has been studied by simultaneous registration of the scattered alpha particles and the secondary pion or proton.

Effective Stochastic Resonance under Heterogeneous Amplitude of Noise [PDF]

open access: yesarXiv, 2009
Effective stochastic resonance (SR) is numerically and analytically studied using a model with coupled two particles exposed to heterogeneous, i.e., particles dependent, amplitude of noise. Compared to previous SR models of single particle and to those of coupled two particles exposed to equivalent amplitude of noise, the present model exhibits a more ...

Effect of ground-state deformation on the isoscalar giant monopole resonance and the first observation of overtones of the isoscalar giant quadrupole resonance in rare-Earth Nd isotopes

open access: yesPhysics Letters B
The strength distributions of the Isoscalar Giant Monopole Resonance (ISGMR) and Isoscalar Giant Quadrupole Resonance (ISGQR) in 142,146−150Nd have been determined via inelastic α-particle scattering with the Grand Raiden (GR) Spectrometer at the ...

Measurement of the B ± production cross-section in pp collisions at s=7 $$ \sqrt{s}=7 $$ and 13 TeV

open access: yesJournal of High Energy Physics, 2017
The production of B ± mesons is studied in pp collisions at centre-of-mass energies of 7 and 13 TeV, using B ± → J/ψ K ± decays and data samples corresponding to 1.0 fb−1 and 0.3 fb−1, respectively.

Self-induced back-action optical trapping in nanophotonic systems

open access: yesNew Journal of Physics, 2015
Optical trapping is an indispensable tool in physics and the life sciences. However, there is a clear trade off between the size of a particle to be trapped, its spatial confinement, and the intensities required.
