Decoupling spin-orbital correlations in a layered manganite amidst ultrafast hybridized charge-transfer band excitation

L. Shen, S. A. Mack, G. Dakovski, G. Coslovich, O. Krupin, M. Hoffmann, S.-W. Huang, Y-D. Chuang, J. A. Johnson, S. Lieu, S. Zohar, C. Ford, M. Kozina, W. Schlotter, M. P. Minitti, J. Fujioka, R. Moore, W-S. Lee, Z. Hussain, Y. Tokura, P. Littlewood, and J. J. Turner

Phys. Rev. B 101, 201103(R) (2020) - Published 12 May, 2020

Femtosecond optical lasers can be used to trigger drastic modifications of a material’s physical properties on the ultrafast timescale, revealing complex, otherwise inaccessible quantum mechanics as well as new processes with potential for creating novel devices with unprecedented high performance. Here, the authors report that the interaction of near-infrared laser light with a promising spin-orbitronics candidate, the layered mixed-valence manganite Nd1xSr1+xMnO4, produces unexpected results, triggering dramatic modifications in the spin state of the material while leaving its orbital state unperturbed. These observations are made with an x-ray free-electron laser, while optical spectroscopy further reveals the specific way electrons transfer within the system. The results open an opportunity to selectively control the spin state while keeping the orbital one intact, an extremely challenging task in strongly correlated electron systems. They pave an avenue for the next generation of multistate logic and memory devices.

Optical spectroscopy and ultrafast pump-probe study on Bi2Rh3Se2: Evidence for charge density wave order formation

T. Lin, L. Y. Shi, Z. X. Wang, S. J. Zhang, Q. M. Liu, T. C. Hu, T. Dong, D. Wu, and N. L. Wang

Phys. Rev. B 101, 205112 (2020) - Published 8 May, 2020

Here, the authors present a detailed investigation of the electrodynamic response of the ternary chalcogenide Bi2Rh3Se2 (of parkerite type), which is a putative charge density wave material. The study implements a combination of broadband optical conductivity and ultrafast pump-probe measurements of photoinduced changes in the reflectivity. Their measurements provide compelling evidence that the phase transition at 240 K in Bi2Rh3Se2 is not a purely structural phase transition, rather, it is linked to the formation of charge density wave order.

Electromagnetic coupling in tight-binding models for strongly correlated light and matter

Jiajun Li, Denis Golez, Giacomo Mazza, Andrew J. Millis, Antoine Georges, and Martin Eckstein

Phys. Rev. B 101, 205140 (2020) - Published 21 May, 2020

The rapidly developing collaboration of condensed matter and quantum optical physics opens up exciting new possibilities for creating novel photon-matter states that allow manipulating material properties using optical cavities. This paper addresses the important challenge of formulating consistent, accurate, and convenient forms of the light-matter coupling for the low-energy tight-binding-type models useful for theoretical analysis. It achieves this by constructing precise mappings from the fundamental ab initio description of the cavity-matter system to low-energy theories, producing a truncated Hamiltonian coupling to a quantum Peierls phase. In a simple model system, the authors demonstrate the quick convergence of the truncated Hamiltonian with the number of bands, paving the way for rigorous theoretical studies in this emerging research field.

Thermoelectric power of Sachdev-Ye-Kitaev islands: Probing Bekenstein-Hawking entropy in quantum matter experiments

Alexander Kruchkov, Aavishkar A. Patel, Philip Kim, and Subir Sachdev

Phys. Rev. B 101, 205148 (2020) - Published 29 May, 2020

One of the remarkable properties of the Sachdev-Ye-Kitaev model of randomly interacting electrons is that it has a nonvanishing extensive entropy in the limit of zero temperature. In its dual representation as the low energy theory of a charged black hole, this entropy is the Bekenstein-Hawking black hole entropy. This work shows how the entropy can be measured by thermoelectric probes of mesoscopic electronic realizations of Sachdev-Ye-Kitaev models.

Chiral quantum optics using a topological resonator

Sabyasachi Barik, Aziz Karasahin, Sunil Mittal, Edo Waks, and Mohammad Hafezi

Phys. Rev. B 101, 205303 (2020) - Published 12 May, 2020

Topological physics has introduced a modern design principle in optics, providing build-in protection to specific types of disorder. This work demonstrates how such principles could be used to create a topological resonator in nanophotonic crystals so as to enable chiral light-matter interaction in the context of cavity quantum electrodynamics. A moderate Purcell effect is shown as an experimental proof of principle.

Spin caloritronics in a CrBr3-based magnetic van der Waals heterostructure

Tian Liu, Julian Peiro, Dennis K. de Wal, Johannes C. Leutenantsmeyer, Marcos H. D. Guimarães, and Bart J. van Wees

Phys. Rev. B 101, 205407 (2020) - Published 6 May, 2020

Exploration of the coupling of charge, heat, and spin is the key for spintronics in two-dimensional van der Waals magnets, as Joule heating is a practical source of generating spin currents strongly linked to the magnetization. Here, the authors present the first measurements of spin caloritronic effects in a two-dimensional ferromagnetic insulator/heavy metal system, paving the way to deeper understanding of magnonic technology, hosted by two-dimensional materials.

Homotopy characterization of non-Hermitian Hamiltonians

Charles C. Wojcik, Xiao-Qi Sun, Tomáš Bzdušek, and Shanhui Fan

Phys. Rev. B 101, 205417 (2020) - Published 15 May, 2020

There has been much recent interest in understanding topological band theory of non-Hermitian systems. Most work has focused on the Chern number in these systems, although interesting phenomena related to an eigenvalue winding number has also been reported. Here, the authors give a complete topological classification using homotopy theory. They find that the Chern number can be reduced modulo 2 depending on the winding number, and this is interpreted in terms of braiding of Weyl points and exceptional nodal rings.

One of the remarkable properties of the Sachdev-Ye-Kitaev model of randomly interacting electrons is that it has a nonvanishing extensive entropy in the limit of zero temperature. In its dual representation as the low energy theory of a charged black hole, this entropy is the Bekenstein-Hawking black hole entropy. This work shows how the entropy can be measured by thermoelectric probes of mesoscopic electronic realizations of Sachdev-Ye-Kitaev models.

Topological physics has introduced a modern design principle in optics, providing build-in protection to specific types of disorder. This work demonstrates how such principles could be used to create a topological resonator in nanophotonic crystals so as to enable chiral light-matter interaction in the context of cavity quantum electrodynamics. A moderate Purcell effect is shown as an experimental proof of principle.

Exploration of the coupling of charge, heat, and spin is the key for spintronics in two-dimensional van der Waals magnets, as Joule heating is a practical source of generating spin currents strongly linked to the magnetization. Here, the authors present the first measurements of spin caloritronic effects in a two-dimensional ferromagnetic insulator/heavy metal system, paving the way to deeper understanding of magnonic technology, hosted by two-dimensional materials.

There has been much recent interest in understanding topological band theory of non-Hermitian systems. Most work has focused on the Chern number in these systems, although interesting phenomena related to an eigenvalue winding number has also been reported. Here, the authors give a complete topological classification using homotopy theory. They find that the Chern number can be reduced modulo 2 depending on the winding number, and this is interpreted in terms of braiding of Weyl points and exceptional nodal rings.
