Undecidability of the Spectral Gap
A fascinating application of computability theory to physics: Undecidability of the Spectral Gap Toby Cubitt, David Perez-Garcia, and Michael M. Wolf The spectral gap—the difference in energy between the ground state and the first excited state—is one of the most important prop- erties of a quantum many-body system. Quantum phase transitions occur when the spectral gap vanishes and the system becomes critical. Much of physicsis concerned with understanding the phase diagrams of quantum systems, and some of the most challenging and long-standing open problems in theoretical physics concern the spectral gap, 1–3 such as the Haldane conjecture 4 that the Heisen- berg chain is gapped for integer spin, proving existence of a gapped topological spin liquid phase, 2,3 or the Yang-Mills gap conjecture 5 (one of the Millennium Prize problems). These problems are all particular cases of the general spectral gap problem: Given a quan- tum many-body Hamiltonian, is the system it describes gapped or gapless? Here we show that this problem is undecidable, in the same sense as the Halting Problem was proven to be undecidable by Turing. 6 A consequence of this is that the spectral gap of certain quantum many-body Hamiltonians is not determined by the axioms of mathematics, much as Gödels incompleteness theorem implies that certain theorems are mathematically unprovable. We extend these results to prove undecidability of other low temperature prop- erties, such as correlation functions. The proof hinges on simple quantum many-body models that exhibit highly unusual physics in the thermodynamic limit. arXiv:1502.04135v1 [quant-ph] 13 Feb 2015 Brent -- You received this message because you are subscribed to the Google Groups "Everything List" group.

Re: Some questions on ontology of dreams
Interesting set-up. Goes around the notion that our 'environment' is a subjective composition upon whatever we (humans etc.) can compose as a result of OUR (partial) views collected from Nature (whatever we call so). Without such composite there is no 'human' identified. The details my learned listers mentioned, are partial consequences, as looked from diverse points of view. (And please, do not even think that in my views either 'ontology', or 'dreams' are objective items in such 'Nature'. Our* virtual subjectivity* (worldview, or call it as you wish - some like to call it* objective reality*) constructs an environment in which the rest of such imagination can exist. So: we are *humans* - etc.) I accept if someone calls my views "un-scientific", I have a pretty lowly opinion about 'science' as we know (construed) it. I am an old (natural) scientist.

The first word of the name should have tipped you off, if QUANTUM field theory is correct then nothing is analog.

When I say that RA proves the existence of the terminating computations, I am saying a standrd result. You oppose this by introducing a notion of physical computation, which you have not yet define. You are using vague undefined notions to criticize standard result in the field. I don't know if math or physics is more fundamental; you don't know either but you think you do. I know nothing. I give a deduction that IF computationalism is correct, then physics cannot be the fundamental science, and the proof is constructive and shows how to derive physics, and I have used this to derive the propositional logic of the observable, and it fits until now with the empirical facts.

Re: Some questions on ontology of dreams
Hi Brian, Telmo and others, On 21 Sep 2015, at 02:49, Telmo Menezes wrote: Hi Brian, That's an interesting question. My take is this: I think trying to understand that experience is like trying to understand what it feels like to be an amoeba. It's just too alien. I am not sure. I can imagine an amoeba having "proto-feeling" comparable to ours. An amoeba or a paramecium might feel something like some urge to find food when hungry, some urge to find a mate, some urge to build a kist due to pollution, ... A monocellular eukaryotic organism is a cell playing the roles of liver cells, digestive cells, skin cells, neuronal cells, muscular cells, etc. In the case of paramecium, this is more or less confirmed by the molecular structure of the cells, in which key molecules playing the corresponding role of each organ can be found. In particular we can anesthetize a paramecium, we can block its locomotion with inhibiters similar to what can inhibit our muscles, etc. (Note that muscular and neuronal key molecules of that type have been found at the base of the roots of plants too, and we can indeed anesthetize plants). The only difficulty for us to imagine what is like to be an amoeba might comes when it divides itself, but then in this list this should no more be a problem (except for Clark and Peck I guess). But this does not solve Brian's difficult question. A human totally deprived of an environment would be more like an encysted amoeba, never going out of its "egg" (cyst), I think its consciousness might be similar to the consciousness of the virgin machine (the non programmed computer), which I think is similar to the consciousness we can have during some phase of sleep or with some drug (notably salvia). That is a consciousness state that we can hardly conceive, because it is not time-related, nor space-related. To imagine it, some thought experience can be given, but they will have to contain "total amnesia", and even this will just be a sort of approximation. In fact such a state of consciousness, even when lived, are not strictly speaking memorable. If some theories are correct, the feeling can be like an "home feeling". It looks like some people getting at that state describe it as the usual, normal consciousness when in absence of any hallucination: it is being like "you" before you begin any differentiation. Even among those who describe it as "home", some are quite positive about it (like bliss) and some are negative about it.. Note that people doing deprivation of input experience in talk deprivation, are actually trying to get closer to such state (and some claims to have found it in that way). Now, it is only recently (well since 2008) that I think that all universal machine are maximally conscious, and why that sort of "blank state", when given information/input, is somehow distracted, and will confuse that "out-of-time" consciousness with its growing content. If such state was too much easily accessible, we would get in there when we have problem, instead of solving the problem, and probably accept equally to eat and to be eaten, which is a good state at the end of life, but handicapping when young where we are supposed to take life, and its information flux, very seriously. We forget quickly our nocturnal dreams for probable similar reason. We have some clues. For example, it is known that if children don't learn a language until a certain age, they become incapable of learning a language forever. There are some instances of this, with children being raised by animals in the wild. I believe we depend on a lot of information that is encoded in the environment to become human. What you describe would be a life form, but not human as we understand it. A developing brain is capable of growing into what we understand to be a human brain, but not by itself. "Humanness" is encoded in the environment, it transcends single bodies or what DNA can encode by itself. I agree with this and what the others said. If you are never feed any input, you are in the state that "you" had before birth, and with some luck, after clinical death (when you don't backtrack on different continuations, if that is possible, as plant and experience reports suggest to be possible). It is not a human state of mind. To be honest, I have done a simplification here, as a fetus *might* have preprogrammed human experiences and skills. Babies seem to be able to swim and walk immediately after birth (like horse), but quickly forget those skills (and perhaps associated experience) to learn them again through the try and error typical way for baby to learn (unlike horse who will just walk instinctively). So, a real human born in a deprivation tank might have some experience, due to the fact that it has some brain, will get food, etc. he will have the sleep phases, and might dream that he
