Isovector neutron-proton pairing with particle number projected BCS
The particle number projected BCS (PBCS) approximation is tested against the exact solution of the SO(5) Richardson-Gaudin model for isovector pairing in a system of nondegenerate single-particle orbits. Two isovector PBCS wave functions are considered. One is constructed as a single proton-neutron pair condensate; the other corresponds to a product of a neutron pair condensate and a proton pai...
متن کاملQuantum Correlations and Number Theory
We study spin-1/2 Heisenberg XXX antiferromagnet. The spectrum of the Hamiltonian was found by Hans Bethe in 1931, [1]. We study the probability of formation of ferromagnetic string in the antiferromagnetic ground state, which we call emptiness formation probability P (n). This is the most fundamental correlation function. We prove that for the short strings it can be expressed in terms of the ...
متن کاملHarmonic resolution as a holographic quantum number
The Bekenstein bound takes the holographic principle into the realm of flat space, promising new insights on the relation of non-gravitational physics to quantum gravity. This makes it important to obtain a precise formulation of the bound. Conventionally, one specifies two macroscopic quantities, mass and spatial width, which cannot be simultaneously diagonalized. Thus, the counting of compati...
متن کاملA Finite Particle Number Approach to Quantum Physics
Bridgman has contended that the "inside of an electron" cannot be given operational meaning. The basic reason for this is taken to be that when relativity is coupled to quantum mechanics the uncertainty principle in energy requires the existence of an indefinitely large number of particulate degrees of freedom corresponding to particles of finite mass when any system is examined at short distan...
متن کاملTgd as a Generalized Number Theory
ions about.... The ordinary second quantized quantum physics corresponds only to thelowest level infinite primes. 2. The ordinary primes appearing as building blocks of infinite primes at the first level of thehierarchy could be identified as coding for p-adic primes assignable to fermionic and bosonicpartons identified as 2-surfaces of a given space-time sheet. The hierarchy of inf...
