The de Broglie Wavelength

33.9K
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...

Atomic Nuclei: Types of Nuclear Relaxation

1.0K
Nuclear relaxation restores the equilibrium population imbalance and can occur via spin–lattice or spin–spin mechanisms, which are first-order exponential decay processes.
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers...

Atomic Nuclei: Nuclear Relaxation Processes

1.3K
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis,  the precessing magnetic moments are randomly oriented around the z-axis.

Radical Chain-Growth Polymerization: Overview01:10

Radical Chain-Growth Polymerization: Overview

3.5K
Chain-growth or addition polymerization is successive addition reactions of monomers with a polymer chain. In radical chain-growth polymerization, the reaction proceeds via a free-radical intermediate. The free radical is formed from radical initiators, which spontaneously generate free radicals by homolytic fission. Organic peroxides (such as dibenzoyl peroxide, as shown in Figure 1) or azo compounds are popular radical initiators. A low concentration ratio of radical initiator to monomer is...

The Quantum-Mechanical Model of an Atom

60.0K
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.

Heating and Cooling Curves02:44

Heating and Cooling Curves

28.2K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

A small ergodic region can destabilize a many-body localized phase. This occurs when the localization length surpasses a critical value, leading to delocalization of the entire system.

Area of Science:

  • Quantum physics
  • Condensed matter physics
  • Statistical mechanics

Background:

  • Many-body localization (MBL) describes a phase of matter immune to thermalization.
  • Griffiths regions, characterized by low disorder, can influence the stability of localized phases.
  • Understanding MBL stability is crucial for quantum information processing and fundamental physics.

Purpose of the Study:

  • To investigate the stability of the many-body localized phase in the presence of a single ergodic grain.
  • To determine the conditions under which an ergodic region can delocalize a localized system.
  • To develop a theoretical framework explaining the observed delocalization phenomenon.

Main Methods:

  • Numerical simulations of a quantum system comprising localized and ergodic regions (modeled with qubits).

  • Analysis of the system's behavior as a function of localization length and disorder.
  • Development of a theoretical model based on local relaxation times and level spacing.

    • Main Results:

    • A small ergodic grain (even three qubits) can delocalize a localized chain.
    • Delocalization occurs when the localization length exceeds a critical value.
    • Numerical findings are in excellent agreement with the developed theoretical predictions.

    Conclusions:

    • The stability of the many-body localized phase is sensitive to the presence of even small ergodic regions.
    • A critical localization length determines the transition from localized to extended regimes.
    • The study provides a robust theoretical explanation for the destabilization of MBL by Griffiths regions.
