Nonequilibrium thermodynamics of quantum friction

D. Reiche, F. Intravaia, J.-T. Hsiang, K. Busch, and B. L. Hu

Phys. Rev. A 102, 050203(R) (2020) - Published 25 November, 2020

Quantum friction is a phenomenon where quantum fluctuations of the electrodynamic vacuum lead to a lateral force between two objects moving relative to each other, thus leading to friction. In this paper, the authors study quantum friction under nonequilibrium conditions and demonstrate that common assumptions such as local thermal equilibrium can contradict basic principles of thermodynamics.

Operational characterization of multipartite nonlocal correlations

Sagnik Dutta, Amit Mukherjee, and Manik Banik

Phys. Rev. A 102, 052218 (2020) - Published 13 November, 2020

Bell nonlocality is a useful resource for, among other things, device-independent quantum information processing where an information task can be achieved without making any assumptions about the internal working of the devices used in the protocol. In this paper, the authors address the case of nonlocal correlations involving more than two parties, building on former seminal work to give a finer characterization of the various types of correlations, and demarcating the boundaries between them.

First law of quantum field thermodynamics

Adam Teixidó-Bonfill, Alvaro Ortega, and Eduardo Martín-Martínez

Phys. Rev. A 102, 052219 (2020) - Published 18 November, 2020

Standard definitions of work distributions in quantum thermodynamics cannot be applied to quantum field theory (QFT), due to the absence of a notion of Gibbs thermality as well as the incompatibility of projective measurements with the relativistic nature of QFT. In this paper, the authors show how to overcome this problem and formulate the first law of thermodynamics within QFT.

Experimental witnessing of the quantum channel capacity in the presence of correlated noise

V. Cimini, I. Gianani, M. F. Sacchi, C. Macchiavello, and M. Barbieri

Phys. Rev. A 102, 052404 (2020) - Published 4 November, 2020

The authors demonstrate an experimental approach to detect lower bounds to the quantum capacity of two-qubit communication channels with correlated noise realized with the polarization degrees of freedom of two photons. The major advantage of this approach is that it does not need a complete experimental reconstruction of the channel.

Computational power of matchgates with supplementary resources

M. Hebenstreit, R. Jozsa, B. Kraus, and S. Strelchuk

Phys. Rev. A 102, 052604 (2020) - Published 5 November, 2020

The authors study the classical simulability and computational power of so-called matchgate circuits in the presence of additional resources, and find striking parallels to the known results for Clifford circuits. They also clarify under which conditions universal quantum computation is achieved with this gate set.

Unified description of interactions and energy loss of particles in dense matter and plasmas

C. D. Archubi and N. R. Arista

Phys. Rev. A 102, 052811 (2020) - Published 13 November, 2020

In this paper, the authors present a unified approach to describe the interaction of charged particles with matter that applies to a very broad range of values of densities, temperatures, and ionization state. It can be used for applications to processes in ionized matter under extreme conditions of densities and temperatures, such as found, e.g., in fusion or astrophysical plasmas.

Nuclear spin-dependent parity-violating effects in light polyatomic molecules

Yongliang Hao, Petr Navrátil, Eric B. Norrgard, Miroslav Iliaš, Ephraim Eliav, Rob G. E. Timmermans, Victor V. Flambaum, and Anastasia Borschevsky

Phys. Rev. A 102, 052828 (2020) - Published 25 November, 2020

Measurements of nuclear spin-dependent parity-violating effects in small molecules provide a promising route to search for physics beyond the standard model. In this paper, the authors lay out a strategy for the complementary determination of both the anapole moment and contributions due to electron-nucleus interactions, and assess the expected sensitivity of such an experiment.

Robust control of an ensemble of springs: Application to ion cyclotron resonance and two-level quantum systems

V. Martikyan, A. Devra, D. Guéry-Odelin, S. J. Glaser, and D. Sugny

Phys. Rev. A 102, 053104 (2020) - Published 4 November, 2020

The authors derive analytical expressions for the control fields and the dynamics of an ensemble of springs with different frequencies. The authors compare three different methods of control: adiabatic, shortcut to adiabaticity, and optimal processes, and apply them to two example systems.

Broadening of the drumhead-mode spectrum due to in-plane thermal fluctuations of two-dimensional trapped ion crystals in a Penning trap

Athreya Shankar, Chen Tang, Matthew Affolter, Kevin Gilmore, Daniel H. E. Dubin, Scott Parker, Murray J. Holland, and John J. Bollinger

Phys. Rev. A 102, 053106 (2020) - Published 5 November, 2020

The authors theoretically and numerically investigate the in-plane motion of two-dimensional ion crystals stored in Penning traps. They find that the thermal fluctuations in the in-plane positions of ions, described by normal modes whose potential energy is several hundred times larger than their kinetic energy, strongly contribute to the spectral broadening of the transverse drumhead motion.

Collective excitations of a spherical ultradilute quantum droplet

Hui Hu and Xia-Ji Liu

Phys. Rev. A 102, 053303 (2020) - Published 4 November, 2020

The authors theoretically investigate how collective excitations of a three-dimensional quantum droplet are affected by the beyond-mean-field quantum fluctuations and a weak harmonic trapping potential. The existence of the surface modes is shown to be robust against the change in both factors.

Symmetry breaking in binary Bose-Einstein condensates in the presence of an inhomogeneous artificial gauge field

S. Sahar S. Hejazi, Juan Polo, Rashi Sachdeva, and Thomas Busch

Phys. Rev. A 102, 053309 (2020) - Published 9 November, 2020

The ground state of interacting two-component Bose-Einstein condensates in the presence of an inhomogeneous artificial gauge potential is found to exhibit symmetry breaking in the phase separated regime. This theoretical work explains that this behavior arises as a consequence of the competition between the interaction and the rotational energies.”

Stability in turbulence: The interplay between shocks and vorticity in a superfluid with higher-order dispersion

M. E. Mossman, E. S. Delikatny, Michael McNeil Forbes, and P. Engels

Phys. Rev. A 102, 053310 (2020) - Published 10 November, 2020

The authors study the shock-wave propagation and dissipation within a spatially asymmetric two-component Bose-Einstein condensate with spin-orbit coupling in a joint experimental and theoretical study. Highly nonlinear dynamics with higher-order dispersion in an ultracold atomic system are observed and investigated.

Symmetric Bloch oscillations of matter waves

Zachary Pagel, Weicheng Zhong, Richard H. Parker, Christopher T. Olund, Norman Y. Yao, and Holger Müller

Phys. Rev. A 102, 053312 (2020) - Published 13 November, 2020

The authors investigate Bloch oscillations of ultracold atoms in two superposed optical lattices that are accelerated away from one another in a joint theoretical and experimental study. The authors also demonstrate that this setup can be used for coherently controlling superpositions of momentum states in atom interferometry.

Controlling the ac Stark effect of RbCs with dc electric and magnetic fields

Jacob A. Blackmore, Rahul Sawant, Philip D. Gregory, Sarah L. Bromley, Jesús Aldegunde, Jeremy M. Hutson, and Simon L. Cornish

Phys. Rev. A 102, 053316 (2020) - Published 17 November, 2020

Effects of static electric and magnetic fields on the differential ac Stark shifts for microwave transitions in ultracold bosonic 87Rb133Cs molecules are studied experimentally. The ac Stark effect is greatly simplified by applying a dc electric field in addition to the magnetic field.

Laser cooling of transition-metal atoms

Scott Eustice, Kayleigh Cassella, and Dan Stamper-Kurn

Phys. Rev. A 102, 053327 (2020) - Published 30 November, 2020

The authors propose the laser cooling scheme for eleven transition-metal atoms, including both bosonic and fermionic species. A number of cycling optical transitions from the ground state or from a long-lived metastable state to the excited states are identified for the cooling scheme.

Vortex-Meissner phase transition induced by a two-tone-drive-engineered artificial gauge potential in the fermionic ladder constructed by superconducting qubit circuits

Yan-Jun Zhao, Xun-Wei Xu, Hui Wang, Yu-xi Liu, and Wu-Ming Liu

Phys. Rev. A 102, 053722 (2020) - Published 24 November, 2020

The authors are proposing a way to engineer artificial gauge fields in systems of superconducting qubits that is applicable, in principle, to circuits with any nonzero anharmonicity, thereby allowing for the simulation of fermionic systems. As an application, they study the transition between vortex and Meissner phases in a two-leg ladder system induced by varying the interleg coupling strength and effective magnetic flux.

Phys. Rev. A 102, 053722 (2020) - Published 24 November, 2020

The authors are proposing a way to engineer artificial gauge fields in systems of superconducting qubits that is applicable, in principle, to circuits with any nonzero anharmonicity, thereby allowing for the simulation of fermionic systems. As an application, they study the transition between vortex and Meissner phases in a two-leg ladder system induced by varying the interleg coupling strength and effective magnetic flux.
