Summary
This summary is machine-generated.We introduce a discrete-time quantum East model, revealing a persistent disorder-free localization transition. This quantum spin chain phenomenon is observable in current digital quantum simulation platforms.
Area Of Science
- Quantum physics
- Condensed matter theory
- Statistical mechanics
Background
- The continuous-time quantum East model exhibits a disorder-free localization transition.
- This transition is characterized by a large family of nonthermal, localized eigenstates.
- Kinetically constrained models are inspired by classical glasses.
Purpose Of The Study
- To investigate the discrete-time version of the quantum East model.
- To determine if the disorder-free localization transition persists in the discrete-time variant.
- To identify observable signatures of this transition in quantum simulations.
Main Methods
- Analytical approaches
- Numerical simulations
- Analysis of nonequilibrium dynamics of the fully polarized state
Main Results
- The disorder-free localization transition is shown to persist for discrete times.
- The transition is present for any finite time step (excluding a zero-measure set).
- The transition can be detected by observing the dynamics of the fully polarized state.
Conclusions
- The discrete-time quantum East model exhibits a robust disorder-free localization transition.
- This transition is experimentally observable in state-of-the-art digital quantum simulation platforms.

The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...
When an object is in equilibrium, it is either at rest or moving with a constant velocity. There are two types of equilibrium: static and dynamic. Static equilibrium occurs when an object is at rest, while dynamic equilibrium occurs when an object is moving with a constant velocity. In both cases, there must be a balance of forces acting on the object.
To understand the concept of equilibrium, let us first consider the forces acting on an object. When different forces act on an object, they can...
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If...
