Dynamics of entanglement and transport in one-dimensional systems with quenched randomness

By Adam Nahum, Jonathan Ruhman, and David A. Huse from Recent Articles in Phys. Rev. B. Published on Jul 16, 2018.

Author(s): Adam Nahum, Jonathan Ruhman, and David A. Huse

The thermalization of one-dimensional quantum systems may be severely slowed by weak links, e.g., by the Griffiths regions that dominate the long-time dynamics of a system close to the many-body-localization transition. Here, the authors construct universal coarse-grained descriptions for entanglement production and for the dynamics of quantum operators in systems with weak links. They reveal unexpected differences between these processes (for example, entanglement growth can be slower than linear in time even when operators spread ballistically). The universal physics is explained using simple classical effective models. The authors’ analysis of the spreading of quantum information and of conserved quantities shows that thermalization in the presence of weak links has a rich structure, featuring multiple dynamic length scales that diverge with different powers of time.

The interaction of excitons with phonons governs energy relaxation, dephasing, and optical transition line broadening with temperature in two-dimensional (2D) materials. Here, the authors observe and study unusual high-energy tails in both absorption and emission extending over several meV in energy at low temperatures. They develop a theory of the effect and show that the coupling between acoustic phonons and excitons lies at the origin for the observed high-energy tails. This work demonstrates that the exciton-phonon coupling in 2D crystals is more efficient as compared with conventional semiconductor structures, such as GaAs/AlGaAs quantum wells.

The spin of an electron is an inherently quantum-mechanical object as it is quantized as half-integer values in the unit of the Planck’s constant. Indeed, a variety of magnetism phenomena arising from interacting spins in crystalline solids are direct consequences of this quantization. Yet the present study reveals that the classical dynamics of spins in frustrated magnets with strong spin-orbit coupling can describe their quantum dynamics at finite temperature. The authors show that this peculiar classical-quantum correspondence originates from the constraints on the relativemotion of spins on the crystalline lattice.

Author(s): Ervand Kandelaki and Mark S. Rudner

We study transient dynamics in a two-dimensional system of interacting Dirac fermions subject to a quenched drive with circularly polarized light. In the absence of interactions, the drive opens a gap at the Dirac point in the quasienergy spectrum, inducing nontrivial band topology. We investigate t...

Charge density wave phase, Mottness, and ferromagnetism in monolayer $1T−{\mathrm{NbSe}}_{2}$

By Diego Pasquier and Oleg V. Yazyev from Recent Articles in Phys. Rev. B. Published on Jul 10, 2018.

Author(s): Diego Pasquier and Oleg V. Yazyev

The metastable 1T polymorph of NbSe2 was recently successfully synthesized in monolayer form. The observation of a superlattice and insulating behavior suggests an analogy with 1T-TaS2, an extensively investigated system known for its complex phase diagram that has recently been suggested to realize a possible quantum spin-liquid ground state. Here, a series of ab initio techniques, from density functional theory (DFT) to dynamical mean-field theory (DMFT), finds that the star-of-David phase in 1T-NbSe2 is the most stable commensurate charge density wave phase and that its electronic character is a Mott insulator. DFT calculations also predict weak nearest-neighbor ferromagnetic coupling, which would disfavor a quantum spin liquid phase but suggest a flat-band ferromagnetism scenario.

Author(s): Gunnar Berghäuser, Philipp Steinleitner, Philipp Merkl, Rupert Huber, Andreas Knorr, and Ermin Malic

Transition-metal dichalcogenides (TMDs) exhibit a remarkable exciton landscape with a majority of optically forbidden dark excitonic states. Here, the authors present a study that combines microscopic theory with femtosecond infrared spectroscopy. It allows to map the excitonic landscape of an arbitrary TMD material by investigating the temporal evolution of the intraexcitonic 1s-2p transition. By resolving the optical response shortly after the excitation and after the exciton thermalization, the authors reveal the relative position of bright and dark excitonic states. The theoretical prediction is confirmed on the exemplary WSe2 material as shown in the picture.

High harmonics from laser-ablated plumes are mostly generated from ionic species. We demonstrate that with ultrashort infrared ($∼1.82\text{ }\text{ }μ\mathrm{m}$) driving lasers, high harmonics from laser-ablated manganese are predominantly generated from neutral atoms, a transition metal atom with...

Author(s): José P. D’Incao, Jia Wang, and V. E. Colussi

We study the impact of three-body physics in quenched unitary Bose gases, focusing on the role of the Efimov effect. Using a local density model, we solve the three-body problem and determine three-body decay rates at unitarity, finding density-dependent, log-periodic Efimov oscillations, violating ...

This fundamental paradigm is challenged by...

One of the most challenging problems in correlated topological systems is a realization of the reduction of topological classification, but very few experimental platforms have been proposed so far.

We study theoretically the nonreciprocal charge transport in two-dimensional noncentrosymmetric superconductors with the Rashba spin-orbit interaction. The resistivity $R$ depends on the current $I$ linearly under the external magnetic field $B$, i.e., $R={R}_{0}(1+γBI)$, which is called the magneto...

Its emergence is caused by an induced nonlocal interaction mediated by density oscillations in the condensate, and we derive using field...
