The Spinless Relativistic Hellmann Problem
Wolfgang Lucha, Franz F. Schöberl
We compile some easily deducible information on the discrete eigenvalue spectra of spinless Salpeter equations encompassing, besides a relativistic kinetic term, interactions which…
The influence of pump coherence on the generation of position-momentum entanglement in down-conversion
Wuhong Zhang, Robert Fickler, Enno Giese +2
Strong correlations in two conjugate variables are the signature of quantum entanglement and have played a key role in the development of modern physics. Entangled photons have bec…
Mind before matter: reversing the arrow of fundamentality
Markus P. Mueller
In this contribution to FQXi's essay contest 2018, I suggest that it is sometimes a step forward to reverse our intuition on "what is fundamental", a move that is somewhat reminisc…
Ultrafast coherent excitation of a Ca ion
D. Heinrich, M. Guggemos, M. Guevara-Bertsch +3
Trapped ions are a well-studied and promising system for the realization of a scalable quantum computer. Faster quantum gates would greatly improve the applicability of such a syst…
Solar bursts as can be observed from the lunar farside with a single antenna at very low frequencies
A. A. Stanislavsky, A. A. Konovalenko, S. N. Yerin +10
Earth-based observations are complicated by the opacity of Earth's ionosphere at very low frequencies and strong man-made radio frequency interference. This explains long standing…
Cosmological beam dump: constraints on dark scalars mixed with the Higgs boson
Anthony Fradette, Maxim Pospelov, Josef Pradler +1
Precision cosmology provides a sensitive probe of extremely weakly coupled states due to thermal freeze-in production, with subsequent decays impacting physics during well-tested c…
A hydrogen beam to characterize the ASACUSA antihydrogen hyperfine spectrometer
C. Malbrunot, M. Diermaier, M. C. Simon +19
The antihydrogen programme of the ASACUSA collaboration at the antiproton decelerator of CERN focuses on Rabi-type measurements of the ground-state hyperfine splitting of antihydro…
Breathing Mode of a BEC Repulsively Interacting with a Fermionic Reservoir
Bo Huang, Isabella Fritsche, Rianne S. Lous +4
We investigate the fundamental breathing mode of a small-sized elongated Bose-Einstein condensate coupled to a large Fermi sea of atoms. Our observations show a dramatic shift of t…
Revisiting the frequency drift rates of decameter type III solar bursts observed in July-August 2002
A. A. Stanislavsky, A. A. Konovalenko, E. P. Abranin +4
Estimating for the frequency drift rates of type III solar bursts is crucial for characterizing their source development in solar corona. According to Melnik et al. (Solar Phys. 26…
On efficient weighted integration via a change of variables
Peter Kritzer, Friedrich Pillichshammer, Leszek Plaskota +1
In this paper, we study the approximation of -dimensional -weighted integrals over unbounded domains or using a special change of variables, s…
Surveying structural complexity in quantum many-body systems
Whei Yeap Suen, Thomas J. Elliott, Jayne Thompson +4
Quantum many-body systems exhibit a rich and diverse range of exotic behaviours, owing to their underlying non-classical structure. These systems present a deep structure beyond th…
Quantum Experiments and Graphs III: High-Dimensional and Multi-Particle Entanglement
Xuemei Gu, Lijun Chen, Anton Zeilinger +1
Quantum entanglement plays an important role in quantum information processes, such as quantum computation and quantum communication. Experiments in laboratories are unquestionably…
Cavity-Based 3D Cooling of a Levitated Nanoparticle via Coherent Scattering
Dominik Windey, Carlos Gonzalez-Ballestero, Patrick Maurer +3
We experimentally realize cavity cooling of all three translational degrees of motion of a levitated nanoparticle in vacuum. The particle is trapped by a cavity-independent optical…
Enhanced continuous generation of non-Gaussianity through optomechanical modulation
Sofia Qvarfort, Alessio Serafini, André Xuereb +2
We study the non-Gaussian character of quantum optomechanical systems evolving under the fully nonlinear optomechanical Hamiltonian. By using a measure of non-Gaussianity based on…
Distribution of short subsequences of inversive congruential pseudorandom numbers modulo
László Mérai, Igor E. Shparlinski
In this paper we study the distribution of very short sequences of inversive congruential pseudorandom numbers modulo . We derive a new bound on exponential sums with such seq…
Optimizing Quantum Error Correction Codes with Reinforcement Learning
Hendrik Poulsen Nautrup, Nicolas Delfosse, Vedran Dunjko +2
Quantum error correction is widely thought to be the key to fault-tolerant quantum computation. However, determining the most suited encoding for unknown error channels or specific…
Coherence and asymmetry cannot be broadcast
Matteo Lostaglio, Markus P. Mueller
In the presence of conservation laws, superpositions of eigenstates of the corresponding conserved quantities cannot be generated by quantum dynamics. Thus, any such coherence repr…
Correlation between the decays in the MSSM with quark flavour violation
H. Eberl, K. Hidaka, E. Ginina
We study the loop-induced decays and in the Minimal Supersymmetric Standard Model (MSSM) with quark flavour violation (QFV), identifying with…
Cluster State Generation with Spin-Orbit Coupled Fermionic Atoms in Optical Lattices
Mikhail Mamaev, Rainer Blatt, Jun Ye +1
Measurement-based quantum computation, an alternative paradigm for quantum information processing, uses simple measurements on qubits prepared in cluster states, a class of multipa…
Time evolution of coupled multimode and multiresonator optomechanical systems
David Edward Bruschi
We study the time evolution of bosonic systems where multiple driven bosonic modes of light interact with multiple mechanical resonators through arbitrary, time-dependent, optomech…
Communication through quantum-controlled noise
