Spintronics advance brings wafer-scale quantum devices closer to reality
Spintronics advance wafer-scale quantum devices
2015/7/13
An electronics technology that uses the “spin”—or magnetization—of atomic nuclei to store and process information promises huge gains in performance over today’s electron-based devices. But getting th...
Quasiparticle light elements and quantum condensates in nuclear matter
Quasiparticle light elements quantum condensates
2011/7/20
Nuclei in dense matter are influenced by the medium. In the cluster mean field approximation, an effective Schr\"odinger equation for the $A$-particle cluster is obtained accounting for the effects of...
Full quantum calculation of Cherenkov gluon radiation by quark and gluon currents and a Cherenkov decay of a gluon into a pair of Cherenkov gluons in transparent media is performed. Energy losses due ...
A Euclidean formulation of relativistic quantum mechanics
relativistic quantum mechanics Euclidean formulation
2011/7/20
In this paper we discuss a formulation of relativistic quantum mechanics that uses Euclidean Green functions or generating functionals as input.
Quantum Monte Carlo calculations of spectroscopic overlaps in $A \leq 7$ nuclei
Quantum Monte Carlo calculations spectroscopic overlaps
2011/7/20
We present Green's function Monte Carlo calculations of spectroscopic overlaps for $A \leq 7$ nuclei. The realistic Argonne v18 two-nucleon and Illinois-7 three-nucleon interactions are used to genera...
Sub-barrier capture with quantum diffusion approach: actinide-based reactions
astrophysical S-factor dissipative dynamics sub-barrier capture
2011/7/20
With the quantum diffusion approach the behavior of capture cross sections and mean-square angular momenta of captured systems are revealed in the reactions with deformed nuclei at subbarrier energies...
Spin operator matrix elements in the quantum Ising chain: fermion approach
Quantum Ising chain form-factors fermions Onsager algebra
2010/11/22
Using some modification of the standard fermion technique we derive factorized formula for
spin operator matrix elements (form-factors) between general eigenstates of the Hamiltonian
of quantum Isin...
How to decompose continuous-variable quantum logic gates
continuous-variable quantum logic gates
2010/10/29
We present a general and relatively efficient method for decomposing an arbitrary exponential operator of bosonic mode operators into a set of universal logic gates. Our work is mainly oriented toward...
Quantum Chaotic Scattering in Microwave Resonators
Quantum Chaotic Scattering Microwave Resonators
2010/4/8
In a frequency range where a microwave resonator simulates a chaotic quantum billiard, we have measured moduli and phases of reflection and transmission amplitudes in the regimes of both isolated and ...
Collective versus Single--Particle Motion in Quantum Many--Body Systems from the Perspective of an Integrable Model
Single--Particle Motion Quantum Many--Body Systems Integrable Model
2010/4/8
We study the emergence of collective dynamics in the integrable Hamiltonian system of two finite ensembles of coupled harmonic oscillators. After identification of a collective degree of freedom, the ...
Proposal for measuring the quantum states of neutrons in the gravitational field with a CCD-based pixel sensor
neutron quantumstate gravitational field CCD
2010/4/12
An experimental setup is proposed for the precise measurement of the quantum states of ultracold neutrons bound in the earth's gravitational field. The experiment utilizes a CCD-based pixel sensor and...
Edge states in graphene quantum dots: Fractional quantum Hall effect analogies and differences at zero magnetic field
Edge states graphene quantum dots Fractional quantum Hall zero magnetic field
2010/4/13
We investigate the way that the degenerate manifold of midgap edge states in quasicircular graphene quantum dots with zig-zag boundaries supports, under free-magnetic-field conditions, strongly correl...
