\"Growth is rarely in a straight line. It is tempting to think otherwise, particularly when looking in the rear view mirror, but anyone faced with plotting the coordinates for a company's growth knows the fallacy of this notion. As much as we like to think of corporate leaders executing sure-fire growth strategies, the truth is far messier: it's more an act of exploration and discovery than a step-by-step process. In Growth in the Age of Complexity, the authors describe in detail how complexity has impacted businesses and the markets in which they compete, and the strategies, mindsets and skillsets required to grow profitably! New strategies are required to navigate the ?Sirens of Growth : the growth plans borne of Industrial Age mindsets that too frequently lead to complexity vs. scale. In addition, companies need to develop an Explorer's Mindset and a Navigator's Skillset to sustain performance. You'll discover how to: Assess where you're truly making money, Reignite your core products and services to drive growth, Incorporate experimentation as a key way to discover new opportunities, Create an operating model for scale, location, and replication, Identify new markets where you are positioned to win, Understand the fundamentals for executing in a distributed organization.\"--Amazon.

Based on a highly regarded lecture course at Moscow State University, this is a clear and systematic introduction to gauge field theory. It is unique in providing the means to master gauge field theory prior to the advanced study of quantum mechanics. Though gauge field theory is typically included in courses on quantum field theory, many of its ideas and results can be understood at the classical or semi-classical level. Accordingly, this book is organized so that its early chapters require no special knowledge of quantum mechanics. Aspects of gauge field theory relying on quantum mechanics are introduced only later and in a graduated fashion--making the text ideal for students studying gauge field theory and quantum mechanics simultaneously. The book begins with the basic concepts on which gauge field theory is built. It introduces gauge-invariant Lagrangians and describes the spectra of linear perturbations, including perturbations above nontrivial ground states. The second part focuses on the construction and interpretation of classical solutions that exist entirely due to the nonlinearity of field equations: solitons, bounces, instantons, and sphalerons. The third section considers some of the interesting effects that appear due to interactions of fermions with topological scalar and gauge fields. Mathematical digressions and numerous problems are included throughout. An appendix sketches the role of instantons as saddle points of Euclidean functional integral and related topics. Perfectly suited as an advanced undergraduate or beginning graduate text, this book is an excellent starting point for anyone seeking to understand gauge fields.

The luxurious detail and intricacy of Stephen Wilson's work reveals his deep interest in the intersection between traditional craft and contemporary culture. Blending couture fabrics, digital renderings, 3D-printed sculptures, laser-engraved acrylics and highly detailed embroidery pieces, Wilson's manipulation of multiple materials produces wholly original works of art. Influenced by pop and street art as well as traditional quilting and handicrafts, he creates each unique piece in his North Carolina studio, using both traditional and modern tools. They often contain millions of stitches and take hundreds of hours to create. His work evokes questions regarding luxury consumerism as he deploys fabrics such as Hermes silk, Chanel wool, and other couture textiles to recreate iconic pop culture images.

Kagome metals AV3Sb51 (where the A can stand for K, Cs or Rb) display a rich phase diagram of correlated electron states, including superconductivity2–4 and density waves5–7. Within this landscape, recent experiments have revealed signs of a transition below approximately 35 K attributed to an electronic nematic phase that spontaneously breaks the rotational symmetry of the lattice8. Here we show that the rotational symmetry breaking initiates universally at a high temperature in these materials, towards the 2 × 2 charge density wave transition temperature. We do this via spectroscopic-imaging scanning tunnelling microscopy and study the atomic-scale signatures of the electronic symmetry breaking across several materials in the AV3Sb5 family: CsV3Sb5, KV3Sb5 and Sn-doped CsV3Sb5. Below a substantially lower temperature of about 30 K, we measure the quantum interference of quasiparticles, a key signature for the formation of a coherent electronic state. These quasiparticles display a pronounced unidirectional feature in reciprocal space that strengthens as the superconducting state is approached. Our experiments reveal that high-temperature rotation symmetry breaking and the charge ordering states are separated from the superconducting ground state by an intermediate-temperature regime with coherent unidirectional quasiparticles. This picture is phenomenologically different compared to that in high-temperature superconductors, shedding light on the complex nature of rotation symmetry breaking in AV3Sb5 kagome superconductors.The charge density wave state in kagome superconductors is not fully understood. Now, evidence suggests that the rotational symmetry of the lattice is broken before coherence of unidirectional quasiparticles is established at a lower temperature.

Layered crystalline materials that consist of transition metal atoms on a kagome network have emerged as a versatile platform for the study of unusual electronic phenomena. For example, in the vanadium-based kagome superconductors AV3Sb5 (where A can stand for K, Cs or Rb), there is a parent charge density wave phase that appears to simultaneously break both the translational and rotational symmetries of the lattice. Here we show a contrasting situation, where electronic nematic order—the breaking of rotational symmetry without the breaking of translational symmetry—can occur without a corresponding charge density wave. We use spectroscopic-imaging scanning tunnelling microscopy to study the kagome metal CsTi3Bi5 that is isostructural to AV3Sb5 but with a titanium atom kagome network. CsTi3Bi5 does not exhibit any detectable charge density wave state, but a comparison to density functional theory calculations reveals substantial electronic correlation effects at low energies. In comparing the amplitudes of scattering wave vectors along different directions, we discover an electronic anisotropy that breaks the sixfold symmetry of the lattice, arising from both in-plane and out-of-plane titanium-derived d orbitals. Our work uncovers the role of electronic orbitals in CsTi3Bi5, suggestive of a hexagonal analogue of the nematic bond order in Fe-based superconductors.Electronic nematic order as a distinct phase in kagome materials without any entanglement with charge density wave or charge stripe order has not been detected. Now, it is observed in a titanium-based kagome metal.

Recently discovered superconductors A V 3 Sb 5 ( A  = K, Rb, Cs) 1 , 2 provide a fresh opportunity to study correlation-driven electronic phenomena on a kagome lattice. The observation of an unusual charge density wave (CDW) in the normal state of all the members of the A V 3 Sb 5 family 2 – 10 has prompted a large effort to identify any ‘hidden’ broken symmetries associated with it. We use spectroscopic-imaging scanning tunnelling microscopy to reveal pronounced intensity anisotropy between the different directions of hexagonal CDW in KV 3 Sb 5 . In particular, we find that one of the CDW directions is distinctly different compared with the other two. This observation points to an intrinsic rotation-symmetry-broken electronic ground state where the symmetry is reduced from sixfold to twofold. Furthermore, in contrast to previous reports 3 , we find that the CDW phase is insensitive to the magnetic-field direction, regardless of the presence or absence of atomic defects. Our experiments, combined with earlier observations of stripe charge ordering in CsV 3 Sb 5 , establish correlation-driven rotation symmetry breaking as a unifying feature of A V 3 Sb 5 kagome superconductors. The precise nature of the charge-density-wave state in kagome superconductors remains unclear. Now, local spectroscopy shows that rotational symmetry in real space is broken, with one direction being distinct from the other two.
