Atomic Nuclei: Nuclear Relaxation Processes01:23

Atomic Nuclei: Nuclear Relaxation Processes

899
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.

First Law: Particles in One-dimensional Equilibrium01:10

First Law: Particles in One-dimensional Equilibrium

7.5K
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...

First Law: Particles in Two-dimensional Equilibrium

11.4K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.
Newton's first law tells us about...

Understanding Memory01:19

Understanding Memory

946
Memory is the retention of information or experiences over time, facilitated through three main processes: encoding, storage, and retrieval. Encoding is the process of inputting information into the memory system. For instance, when listening to a lecture, watching a play, reading a book, or having a conversation, the brain is actively encoding information. This initial stage involves transforming sensory input into a form that can be processed and stored by the brain. Various factors, such as...

Implicit Memories01:24

Implicit Memories

284
Implicit memories, also known as non-declarative memories, are long-term memories that function outside of conscious awareness. These memories influence behavior and skills without explicit knowledge. This type of memory is evident in tasks like playing tennis, snowboarding, and texting. Implicit memory has three subsystems: procedural memory, conditioning, and priming. This type of memory is essential in various activities, from everyday tasks to specialized skills.
One key aspect of implicit...

Long-Term Memory01:18

Long-Term Memory

404
Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...

Summary
This summary is machine-generated.

Materials exhibit memory effects below a specific onset condition, with distinct states observed above it. This study confirms the thermodynamic and dimensional robustness of this phenomenon using simulations.

Area of Science:

  • Physics
  • Materials Science

Background:

  • Materials memory in liquids, first observed in simulations over 20 years ago, lacks a clear physical origin.
  • Its absence in mean-field descriptions has raised questions about its thermodynamic relevance.

Purpose of the Study:

  • To reassess the onset phenomenology of materials memory in liquid simulations.
  • To investigate the thermodynamic and dimensional robustness of this phenomenon.
  • To explore a potential second type of memory linked to a Gardner-like regime.

Main Methods:

  • Utilized a fast hard sphere jamming algorithm for simulations.
  • Reassessed onset phenomenology based on a recent theoretical proposal.

Main Results:

  • Confirmed that liquids below an onset condition share similar inherent states, while those above differ markedly.
  • Established the thermodynamic and dimensional robustness of the onset condition.
  • Discovered a second type of memory associated with a Gardner-like regime within the jamming algorithm.

Conclusions:

  • The materials memory phenomenon is thermodynamically and dimensionally robust.
  • A novel Gardner-like memory regime has been identified in jamming simulations.
  • This research clarifies the physical origin and thermodynamic relevance of materials memory.
