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...
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...
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 ...

2010/12/21
On the basis of our recent modifications of the Dirac formalism we general-ize the Bargmann-Wigner formalism for higher spins to be compatible with other formalisms for bosons.

Higher Spins Open Strings Quartic Interactions
2010/12/22
We analyze quartic gauge-invariant interactions of massless higher spin fields by using vertex operators constructed in our previous works and computing their four-point amplitudes in superstring the...

We study the entanglement dynamics for a two-spin system coupled to a spin environment of
different configurations by z-x type interaction. The models considered in this paper are solved both analyti...

2010/3/10
It is known that arrays of trapped ions can be used to efficiently simulate a variety of many-body quantum systems. Here, we show how it is possible to build a model representing a spin chain interact...
Physicists in the US have developed a new kind of thermometer that can measure down to as low as one billionth of a degree above absolute zero and has the potential to reach just a few trillionths of ...

This article aims to review the developments, both theoretical and experimental, that have in the past decade laid the ground for a new approach to solid state quantum computing. Measurement-based qua...
We review our recent work towards quantum communication in a solid-state environment with qubits carried by electron spins. We propose three schemes to produce spin-entangled electrons, where the requ...
