Glass relaxation and hysteresis of the glass transition by molecular dynamics simulations

By Zegao Liu, Yushu Hu, Xin Li, Weiying Song, Sushmit Goyal, Matthieu Micoulaut, and Mathieu Bauchy from Recent Articles in Phys. Rev. B. Published on Sep 21, 2018.

Author(s): Zegao Liu, Yushu Hu, Xin Li, Weiying Song, Sushmit Goyal, Matthieu Micoulaut, and Mathieu Bauchy

Synthesizing Coulombic superconductivity in van der Waals bilayers

By Valla Fatemi and Jonathan Ruhman from Recent Articles in Phys. Rev. B. Published on Sep 19, 2018.

Author(s): Valla Fatemi and Jonathan Ruhman

The emerging field of van der Waals heterostructures promises the engineering of quantum ground states by combining materials with different properties. A special point of interest is the synthesis of new superconductors. Here, the authors explore the idea of combining very fast electrons with very slow ones, proposing a bilayer heterostructure consisting of monolayer graphene (fast) on top of a monolayer semiconducting transition metal dichalcogenide WSe2 (slow). This interesting two liquid model generates a slow plasmonic mode that acts somewhat like phonons in a crystal, which can mediate an attractive interaction to make graphene superconducting. This mechanism for superconductivity is found to be uniquely optimized in van der Waals heterostructures, and the transition temperature is estimated to be in the range of 0.1 Kelvin. If such a superconductor were realized in an experiment, it would be a special example in which attraction between electrons is clearly mediated by electrons.

Transverse vortex commensurability effect and sign change of the Hall voltage in superconducting ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7−δ}$ thin films with a nanoscale periodic pinning landscape

By G. Zechner, W. Lang, M. Dosmailov, M. A. Bodea, and J. D. Pedarnig from Recent Articles in Phys. Rev. B. Published on Sep 18, 2018.

Author(s): G. Zechner, W. Lang, M. Dosmailov, M. A. Bodea, and J. D. Pedarnig

In superconductors with a periodic pinning potential, the vortices can lock into a commensurate arrangement, where each pin is filled by one vortex. Then, an intriguing duality between conduction electrons in a normal metal and mobile vortices in a superconductor arises. While the mutual repulsion of electrons can evoke a Mott insulator, the interaction between mobile and commensurably trapped vortices can lead to a vortex Mott metal-to-insulator transition with vanishing resistance. The authors report on a hitherto unknown manifestation of such a state, uncovered by measurements of the voltage orthogonal to the injected current. This vortex Hall effect exhibits a sharp peak and a change of sign when the number of vortices exactly matches that of the pins.

Theory of spin Bott index for quantum spin Hall states in nonperiodic systems

By Huaqing Huang and Feng Liu from Recent Articles in Phys. Rev. B. Published on Sep 17, 2018.

Author(s): Huaqing Huang and Feng Liu

Quantum spin Hall effects (QSHE) arising from electron band topology are usually limited to crystals. Here, the authors extend the concept of QSHE to nonperiodic systems. They derive a spin Bott index to characterize the electronic topology in aperiodic and amorphous systems, and confirm its applicability by realizing the QSHE in quasicrystals. As in crystals, the QSHE in quasicrystals manifests with robust metallic edge states and quantized conductance. Their findings not only provide a better understanding of electronic properties of nonperiodic systems, but also extend the search of the QSH phase to aperiodic and amorphous materials that are experimentally feasible.

By André P. Vieira and José A. Hoyos from Recent Articles in Phys. Rev. B. Published on Sep 14, 2018.

Author(s): André P. Vieira and José A. Hoyos

We uncover a novel mechanism for inducing a gapful phase in interacting many-body quantum chains. The mechanism is nonperturbative, being triggered only in the presence of both strong interactions and strong aperiodic (disordered) modulation. In the context of the critical antiferromagnetic spin-1/2...

Author(s): Y. Nishikawa, O. J. Curtin, A. C. Hewson, and D. J. G. Crow

We show that when there is a sudden transition from a small to a large Fermi surface at a field-induced quantum critical point—similar to what may have been observed in some heavy-fermion compounds—an additional term has to be taken into account in the Luttinger-Friedel sum rule. We calculate this a...

Two Diverging Length Scales in the Structure of Jammed Packings

By Daniel Hexner, Andrea J. Liu, and Sidney R. Nagel from Recent Articles in Phys. Rev. Lett.. Published on Sep 11, 2018.

Author(s): Daniel Hexner, Andrea J. Liu, and Sidney R. Nagel

At densities higher than the jamming transition for athermal, frictionless repulsive spheres we find two distinct length scales, both of which diverge as a power law as the transition is approached. The first, ${ξ}_{Z}$, is associated with the two-point correlation function for the number of contact...

Author(s): Akitoshi Shiotari, Takafumi Odani, and Yoshiaki Sugimoto

We demonstrated that a nitric oxide (NO) molecule on Cu(110) acts as an “ON-OFF-ON toggle switch” that can be turned on and off by repulsive force and electron injection, respectively. On the surface, NO molecules exist in three configurations: flat along the [001] direction (ON), upright (OFF), and...
