Naturalistic Observations

17.6K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.2K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

Amino acids

106.6K
Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

Summary

Dirac semimetals exhibit a novel quantum phenomenon called the mirror anomaly. This anomaly causes unique, step-like changes in their electrical conductivity when subjected to a magnetic field.

Area of Science:

  • Condensed Matter Physics
  • Quantum Materials
  • Topological Matter

Background:

  • Dirac semimetals are a class of materials exhibiting unique electronic properties.
  • Quantum anomalies, such as the chiral anomaly, play a crucial role in understanding exotic phenomena in these materials.
  • The response of Dirac semimetals to external fields is a key area of research.

Purpose of the Study:

  • To identify and characterize a new quantum anomaly in Dirac semimetals, termed the mirror anomaly.
  • To investigate the manifestation of this anomaly in the material's response to magnetic fields.
  • To establish an analogy between the mirror anomaly and the parity anomaly in lower dimensions.

Main Methods:

  • Theoretical analysis of Dirac semimetals in the presence of magnetic fields.

    • Demonstration of emergent mirror symmetry near time-reversal invariant momenta, analogous to parity symmetry.

    Conclusions:

    • The mirror anomaly represents a novel quantum phenomenon in Dirac semimetals.
    • This anomaly leads to unique, quantized responses in electrical conductivity under magnetic fields.
    • The findings provide new insights into topological properties and symmetries in quantum materials.
