![]() ![]() The workforce isn’t what it used to be either. 3 Project work, one example of nonroutine activity, has increased 40-fold over the past 20 years, making collaboration and teamwork more important than ever. ![]() And the work itself is less routine, with the growth in nonroutine tasks outpacing routine tasks by 20 percentage points since 1960. 2 Technological advances, globalization and the rise of knowledge work have resulted in work and workers being less bound to physical locations or set hours teams are often dispersed across locations and time zones. 1 Organizational structures are, on average, 25 percent flatter than they were 20 years ago. While 60 percent of corporate value creation once depended on hard assets, now more than 85 percent relies on the intangible assets of brand, people and intellectual property. ![]() Ultimately, the ladder’s one-size-fits-all approach assumes employees are more alike than different, and want and need similar things to deliver results.īut the workplace isn’t what it used to be. It defines career success as a linear climb to the top. Its hierarchical structure governs how information flows and whose ideas matter. The ladder proffers a worldview in which power, rewards and access to information are tied to the rung each employee occupies. (1982), Exactly solved models in statistical mechanics (PDF), London: Academic Press Inc.The corporate ladder model took hold at a time when the central business goal in the emerging industrial economy was achieving economies of scale. A lattice Λ is a Wick rotated version of the action in quantum field theory.Įxamples Condensed matter physics.Lattice models are also used to simulate the structure and dynamics of polymers.Ī number of lattice models can be described by the following data: More generally, lattice gauge theory and lattice field theory are areas of study. However, digital physics considers nature fundamentally discrete at the Planck scale, which imposes upper limit to the density of information, aka Holographic principle. An example of a continuum theory that is widely studied by lattice models is the QCD lattice model, a discretization of quantum chromodynamics. Physical lattice models frequently occur as an approximation to a continuum theory, either to give an ultraviolet cutoff to the theory to prevent divergences or to perform numerical computations. ![]() The solution of these models has given insights into the nature of phase transitions, magnetization and scaling behaviour, as well as insights into the nature of quantum field theory. Techniques for solving these include the inverse scattering transform and the method of Lax pairs, the Yang–Baxter equation and quantum groups. The exact solution to many of these models (when they are solvable) includes the presence of solitons. Lattice models are also ideal for study by the methods of computational physics, as the discretization of any continuum model automatically turns it into a lattice model. Some models are exactly solvable, and thus offer insight into physics beyond what can be learned from perturbation theory. Currently, lattice models are quite popular in theoretical physics, for many reasons. Lattice models originally occurred in the context of condensed matter physics, where the atoms of a crystal automatically form a lattice. In physics, a lattice model is a physical model that is defined on a lattice, as opposed to the continuum of space or spacetime. Lattices such as this are used - for example - in the Flory–Huggins solution theory A three-dimensional lattice filled with two molecules A and B, here shown as black and white spheres. ![]()
