Ultralong Dephasing Times in Solid-State Spin Ensembles via Quantum Control
(American Physical Society (APS), 2018-07-25)
Quantum spin dephasing is caused by inhomogeneous coupling to the environment, with resulting limits to the measurement time and precision of spin-based sensors. The effects of spin dephasing can be especially pernicious ...
Contribution of quasar-driven outflows to the extragalactic gamma-ray background
(Springer Science and Business Media LLC, 2016-07-25)
The origin of the extragalactic γ-ray background permeating throughout the Universe remains a mystery forty years after its discovery. The extrapolated population of blazars can account for only half of the background ...
Scalable Quantum Simulation of Molecular Energies
(American Physical Society (APS), 2016-07-18)
Magnetostatic twists in room-temperature skyrmions explored by nitrogen-vacancy center spin texture reconstruction
(Springer Science and Business Media LLC, 2018-07-13)
Magnetic skyrmions are two-dimensional non-collinear spin textures characterized by an integer topological number. Room-temperature skyrmions were recently found in magnetic multilayer stacks, where their stability was ...
Faster than classical quantum algorithm for dense formulas of exact satisfiability and occupation problems
(IOP Publishing, 2016-07-01)
We present an exact quantum algorithm for solving the Exact Satisfiability (XSAT) problem, which belongs to the important NP-complete complexity class. The algorithm is based on an intuitive approach that can be divided ...
Vibrational relaxation of CO by collisions with 4He at ultracold temperatures
(AIP Publishing, 2000-07-08)
Quantum mechanical coupled channel scattering calculations are performed for the ro-vibrational relaxation of CO in collisions with ultracold He atoms. The van der Waals well in the interaction potential supports a number ...
Poroelastic relaxation indentation of thin layers of gels
(AIP Publishing, 2011-10-15)
We develop a method of poroelastic relaxation indentation (PRI) to characterize thin layers of gels. The solution to the time-dependent boundary-value problem is obtained in a remarkably simple form, so that the force-relaxation ...
Search for the Dimuon Decay of the Higgs Boson in pp Collisions at s√ = 13 TeV with the ATLAS Detector
(American Physical Society (APS), 2017-08-04)
A search for the dimuon decay of the Higgs boson was performed using data corresponding to an integrated luminosity of 36.1 fb−1 collected with the ATLAS detector in pp collisions at s√=13 TeV at the Large Hadron Collider. ...
Bounding the costs of quantum simulation of many-body physics in real space
(IOP Publishing, 2017-06-29)
We present a quantum algorithm for simulating the dynamics of a first-quantized Hamiltonian in real space based on the truncated Taylor series algorithm. We avoid the possibility of singularities by applying various cutoffs ...
Minimalist approach to the classification of symmetry protected topological phases
