Web21 de mar. de 2024 · The quantization of the mirror curve to a toric Calabi-Yau threefold gives rise to quantum-mechanical operators. Their fermionic spectral traces produce factorially divergent power series in the Planck constant, which are conjecturally captured by the refined topological string in the Nekrasov-Shatashvili limit via the Topological …

Direct and Inverse Spectral Problems for Generalized Strings

WebIn physics, a continuous spectrum usually means a set of achievable values for some physical quantity (such as energy or wavelength), best described as an interval of real numbers. It is the opposite of a discrete spectrum, a set of achievable values that are discrete in the mathematical sense where there is a positive gap between each value. Web23 de jun. de 2011 · Surprisingly, the spectral function does not exhibit a Fermi surface, despite the fact that the system is at finite charge density. We show that it has a phonino pole and at low frequencies there is a depletion of spectral weight with a power-law scaling which is governed by a locally quantum critical point. bioethical concept of non-maleficence

WebAsync Functions. As of Spectral 5.4.0, custom functions can also be asynchronous. Ideally linting should always be deterministic, which means if it's run 10 times it should return the same results 10 times. To ensure this is the case, please refrain from introducing any logic that is prone to non-deterministic behavior.
