Holding the right material at the right angle, Cornell researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet – a technique that could eventually lead to th...

Numerical experiments with rubble piles:equilibrium shapes and spins
Asteroids Planetesimals Rotational dynamics Solid body tides Satellites of Jupiter
2015/12/25
We present numerical experiments investigating the shape and spin limits of self-gravitating “perfect” rubble piles that consist of identical, smooth, rigid, spherical particles with configurable norm...
Collective dynamics of interacting Ising spins: Exact results for the Bethe lattice
Low temperature dynamic molecules magnet crystal electron spin ground state electronic since the gyration mechanics coupling nuclear
2014/12/19
We study the low temperature dynamics in films made of molecular magnets, i. e. crystals composed of molecules having large electronic spin S in their ground state. The electronic spin dynamics is med...
The purpose of this work is to serve as an introduction to quantum chaos. We avoid the usual path of dealing with ensembles of random matrices and instead consider clean one-dimensional systems of spi...
Addressing the spin question in gravitational-wave searches: Waveform templates for inspiralling compact binaries with nonprecessing spins
Addressing spin question gravitational-wave searches Waveform templates inspiralling
2011/10/18
This paper presents a post-Newtonian (PN) template family of gravitational waveforms from inspiralling compact binaries with non-precessing spins, where the spin effects are described by a single "red...
Initial data for binary neutron stars with arbitrary spins
Initial data binary neutron stars arbitrary spins
2011/10/18
In general neutron stars in binaries are spinning. Due to the existence of millisecond pulsars we know that these spins can be substantial. We argue that spins with periods on the order a few dozen mi...
Mergers of black-hole binaries with aligned spins: Waveform characteristics
Mergers black-hole binaries aligned spins Waveform characteristics
2011/10/18
We conduct a descriptive analysis of the multipolar structure of gravitational-radiation waveforms from equal-mass aligned-spin mergers, following an approach first presented in the complementary cont...
Physicists in the US and the UK have found a way to store and read data in nuclear spins using electronic pulses. The breakthrough could help in the development of spintronic systems that process info...
The Bargmann-Wigner Formalism for Higher Spins (up to 2)
The Bargmann-Wigner Formalism Higher Spins
2010/12/24
On the basis of our recent modifications of the Dirac formalism we generalize the Bargmann-Wigner formalism for higher spins to be compatible with other formalisms for bosons. Relations with dual elec...
Isospin symmetry breaking at high spins in the mirror pair 67Se and 67As
Isospin symmetry breaking high spins mirror pair 67Se and 67As
2011/1/7
Recent experimental data have revealed large mirror energy differences (MED) between high-spin states in the mirror nuclei 67Se and 67As, the heaviest pair where MED have been determined so far. The M...
Induced Rotation in 3D Simulations of Core Collapse Supernovae: Implications for Pulsar Spins
Induced Rotation 3D Simulations Core Collapse Supernovae
2011/1/11
It has been suggested that the observed rotation periods of radio pulsars might be induced by a non-axisymmetric spiral-mode instability in the turbulent region behind the stalled supernova bounce sho...
Nuclear spins, magnetic moments and quadrupole moments of Cu isotopes from N = 28 to N = 46: probes for core polarization effects
Nuclear spins magnetic moments quadrupole moments Cu isotopes probes core polarization effects
2010/12/31
Measurements of the ground-state nuclear spins, magnetic and quadrupole moments of the copper isotopes from 61Cu up to 75Cu are reported. The experiments were performed at the ISOLDE facility, using t...
Quasistationarity in a model of classical spins with long-range interactions
Quasistationarity model of classical spins long-range interactions
2010/11/17
Systems with long-range interactions, while relaxing towards equilibrium, sometimes
get trapped in long-lived non-Boltzmann quasistationary states (QSS) which have lifetimes that
grow algebraically ...
