Q: Are there any 2D materials besides graphene whose bonding can be best described as metalic rather than covalent?

uhohWikipedia's The nature of metallic bonding; In 2D says: Graphene is an example of two-dimensional metallic bonding. Its metallic bonds are similar to aromatic bonding in benzene, naphthalene, anthracene, ovalene, etc. Most 2D materials currently studied tend to fall into two categories; 2D Xen...

@uhoh the simplest google search found an entire book titled 2D Metallic Transition Metal Dichalgogenides
Also, at that level of precision, you ought to be careful enough to state that graphene is a semi-metal and not just a metal.

@naturallyInconsistent I didn't "state" either. And don't confuse adjectives that describe the electrical or optical behavior of a material with adjectives that behave the chemical bonds. Apples and oranges.
"metallic property" ≠ "metallic bond"

hi
@ACuriousMind how to decide when to stop going into the details of a field
the approach i have so far is to avoid reading reference books and to read introductory books of a field and leave it @ACuriousMind

The most "useful" formulas are the ones applied to the right situation in life, is this correct?
Like if you're not worries about accuracy/precision and error propagation u can use the most resource efficient stuff but it depends on what you're doing I guess that's too general
How do I bridge my understanding of theory with the real world? I started studying numerical analysis, but that's more for approximation methods
I guess I have to learn more experimental/applied stuff

@SillyGoose Make any progress in thinking abt time?
I think Brian greene said something abt emergence of time from something related to GR idk lemme find it
sry for the quality
@Obliv jk this is not at all what he said lol

well, unlike some pure maths or string theory or whatnot, numerical analysis is entirely applied maths. Emphasis applied.

Must a physics graduate have experience with research employing computation to get a job about quantum computation?

@ACuriousMind Hi, would you have time to discuss a bit about what we talked yesterday?
Can we clear out the concept of a mode. From my understanding, there is no clear cut defition for a mode. I wrote the following thread a while ago, regarding this topic:
