Rev. A 107, 032609 (2023) – Published 17 March 2023 Quantum control pulses, used to produce desired states in quantum technology applications, can be problematically sensitive to disorder. Here, the authors develop a systematic approach to finding quantum control pulses that are robust in realistic scenarios by translating disorder into a quantum master equation and maximizing the purity of the resulting density matrix.     Editors' Suggestion Macroscopic quantum electrodynamics theory of resonance energy transfer involving chiral molecules Janine Christine Franz, Stefan Yoshi Buhmann, and A. Salam Phys. Rev. A 107, 032809 (2023) – Published 10 March 2023 The authors develop an approach for studying resonant energy transfer between two chiral molecules embedded in a homogeneous medium as a means for chiral discrimination. They find that the degree of discrimination is usually larger for large intermolecular distances, and can be modified by modifying the surrounding medium.     Editors' Suggestion Anisotropic acoustics in dipolar Fermi gases Reuben R. W. Wang and John L. Bohn Phys. Rev. A 107, 033321 (2023) – Published 20 March 2023 The authors theoretically study the propagation of plane wave modes in ultracold dipolar Fermi gases in the hydrodynamic limit, including collisions and mean-field dipolar interactions. The authors find that longitudinal waves present anisotropies in both the speed of sound and damping. In addition, two types of shear waves are predicted, which could be used as an experimental means to measure the viscosity coefficients.     Editors' Suggestion Accuracy of quantum simulators with ultracold dipolar molecules: A quantitative comparison between continuum and lattice descriptions Michael Hughes, Axel U. J. Lode, Dieter Jaksch, and Paolo Molignini Phys. Rev. A 107, 033323 (2023) – Published 22 March 2023 The authors perform a quantitative comparison between the continuum description of a one-dimensional gas of dipolar bosons in an optical lattice and the single-band Bose-Hubbard lattice model that it simulates. Discrepancies are found in regimes with strong dipole-dipole interactions and high densities in the continuum system.     Editors' Suggestion Lee-Yang theory of Bose-Einstein condensation Fredrik Brange, Tuomas Pyhäranta, Eppu Heinonen, Kay Brandner, and Christian Flindt Phys. Rev. A 107, 033324 (2023) – Published 23 March 2023 Bose gases form into Bose-Einstein condensates at a certain transition temperature, at which a large fraction of bosons in the gas become cool enough to occupy the lowest quantum state together. Here, taking inspiration from recent advances in Lee-Yang theories of phase transitions, the authors demonstrate a method to predict this condensation temperature for an ideal gas of billions of bosons using the energy fluctuations of less than a hundred bosons.     Editors' Suggestion Static and dynamic properties of self-bound droplets of light in hot vapors Heitor da Silva, Robin Kaiser, and Tommaso Macrì Phys. Rev. A 107, 033519 (2023) – Published 24 March 2023 The authors explore analogies between self-bound droplet states in Bose-Einstein condensates (BECs) and the propagation of light in nonlinear hot vapor mediums. They establish a mapping between the experimental parameters used in BEC experiments and those needed to observe the analogous phenomenon in hot atomic vapors.     Editors' Suggestion Position measurement and the Huygens-Fresnel principle: A quantum model of Fraunhofer diffraction for polarized pure states Bernard Fabbro Phys. Rev. A 107, 033706 (2023) – Published 8 March 2023 Starting only from the postulates of quantum mechanics, the author presents a model of Fraunhofer diffraction by an aperture by treating the diaphragm as a position-measurement device, and explains how this model leads to experimentally testable consequences for large diffraction angles and polarization of the diffracted light.       American Physical Society: 1 Physics Ellipse, College Park, MD 20740 ©2023 American Physical Society | All rights reserved   You are receiving this email because you are subscribed to Table of Content alerts.
