Atomistic modeling of a superconductor–transition metal dichalcogenide–superconductor Josephson junction
Jouko Nieminen, Sayandip Dhara, Wei-Chi Chiu, Eduardo R. Mucciolo, and Arun Bansil
Author(s): Jouko Nieminen, Sayandip Dhara, Wei-Chi Chiu, Eduardo R. Mucciolo, and Arun Bansil

Using an atomistic tight-binding model, we investigate the characteristics of a Josephson junction formed by monolayers of ${\mathrm{MoS}}_{2}$ sandwiched between Pb superconducting electrodes. We derive and apply Green's function–based formulation to compute the Josephson current as well as the loc…

Electron-phonon coupling superconductivity and tunable topological state in carbon-rich selenide monolayers
Panlong Kong, Xiaotao Zhang, Jingjing Wang, Wenhui Tian, Yuxiang Ni, Bai Sun, Hongyan Wang, Hui Wang, Yuan Ping Feng, and Yuanzheng Chen
Author(s): Panlong Kong, Xiaotao Zhang, Jingjing Wang, Wenhui Tian, Yuxiang Ni, Bai Sun, Hongyan Wang, Hui Wang, Yuan Ping Feng, and Yuanzheng Chen

The coexistence of Dirac cones and Van Hove singularities (VHSs), as the notable feature on prominent electronic band structure in recently hot-topic Lieb lattice and twisted graphene superlattice materials, has recently drawn tremendous attention since it offers an ideal platform for realizing corr…

Wave-packet spreading in the disordered and nonlinear Su-Schrieffer-Heeger chain
Bertin Many Manda, Vassos Achilleos, Olivier Richoux, Charalampos Skokos, and Georgios Theocharis
Author(s): Bertin Many Manda, Vassos Achilleos, Olivier Richoux, Charalampos Skokos, and Georgios Theocharis

We numerically investigate the characteristics of the long-time dynamics of a single-site wave-packet excitation in a disordered and nonlinear Su-Schrieffer-Heeger model. In the linear regime, as the parameters controlling the topology of the system are varied, we show that the transition between tw…

Mott-moiré excitons
Tsung-Sheng Huang, Yang-Zhi Chou, Christopher L. Baldwin, Fengcheng Wu, and Mohammad Hafezi
Author(s): Tsung-Sheng Huang, Yang-Zhi Chou, Christopher L. Baldwin, Fengcheng Wu, and Mohammad Hafezi

We develop a systematic theory for excitons subject to Fermi-Hubbard physics in moiré twisted transition metal dichalcogenides (TMDs). Specifically, we consider excitons from two moiré bands with a Mott-insulating valence band sustaining ${120}^{∘}$ spin order. These “Mott-moiré excitons,” which are…

Highly efficient and indistinguishable single-photon sources via phonon-decoupled two-color excitation
Luca Vannucci and Niels Gregersen
Author(s): Luca Vannucci and Niels Gregersen

Single-photon sources with near-unity efficiency and indistinguishability play a major role in the development of quantum technologies. However, on-demand excitation of the emitter imposes substantial limitations to the source performance. Here, we show that coherent two-color pumping allows for pop…

Transferring orbital angular momentum to an electron beam reveals toroidal and chiral order

Orbital angular momentum (OAM) and torque transfer play central roles in a wide range of magnetic textures and devices including skyrmions and spin-torque electronics. Analogous topological structures are now also being explored in ferroelectrics, including polarization vortex arrays in ferroelectri…

Coupling of magnetism and Dirac fermions in ${\mathrm{YbMnSb}}_{2}$
Xiao Hu, Aashish Sapkota, Zhixiang Hu, Andrei T. Savici, Alexander I. Kolesnikov, John M. Tranquada, Cedomir Petrovic, and Igor A. Zaliznyak
Author(s): Xiao Hu, Aashish Sapkota, Zhixiang Hu, Andrei T. Savici, Alexander I. Kolesnikov, John M. Tranquada, Cedomir Petrovic, and Igor A. Zaliznyak

We report inelastic neutron scattering measurements of magnetic excitations in ${\mathrm{YbMnSb}}_{2}$, a low-carrier-density Dirac semimetal in which the antiferromagnetic Mn layers are interleaved with Sb layers that host Dirac fermions. We observe a measurable broadening of spin waves, which is c…

Exchange-Driven Intermixing of Bulk and Topological Surface States by Chiral Excitons in ${\mathrm{Bi}}_{2}{\mathrm{Se}}_{3}$
Bowen Hou, Dan Wang, Bradford A. Barker, and Diana Y. Qiu
Author(s): Bowen Hou, Dan Wang, Bradford A. Barker, and Diana Y. Qiu

Topological surface states (TSS) in the prototypical topological insulator (TI) ${\mathrm{Bi}}_{2}{\mathrm{Se}}_{3}$ are frequently characterized using optical probes, but electron-hole interactions and their effect on surface localization and optical response of the TSS remain unexplored. Here, we …

A critical end point above which an isotropic phase continuously evolves into a polar (ferroelectric) nematic phase with an increasing electric field is found in a ferroelectric nematic liquid crystalline material. The critical end point is approximately 30 K above the zero-field transition temperat…

Author(s): Abigail N. Poteshman, Mathieu Ouellet, Lee C. Bassett, and Dani S. Bassett

Across all scales of the physical world, dynamical systems can be usefully represented as abstract networks that encode the systems' units and interunit interactions. Understanding how physical rules shape the topological structure of those networks can clarify a system's function and enhance our ab…
