2-LOOP ANALYSIS OF VECTOR-CURRENT PROPAGATORS IN CHIRAL PERTURBATION-THEORY
Isospin hypercharged vector breeding experts chiral perturbation theory
2014/12/23
We perform a calculation of the isospin and hypercharge vector-current propagators (ΔV33μν(q2) and ΔV88μν(q2)) to two loops in chiral perturbation theory. The analysis is carried out with straight-for...
Power counting of loop diagrams in general relativity
Cyclic graph the general theory of relativity energy expansion quantum effects physical power calculation
2014/12/23
A class of loop diagrams in general relativity appears to have a behavior which would upset the utility of the energy expansion for quantum effects. We show through the study of specific diagrams that...

2014/12/22
We perform a calculation of the isospin and hypercharge axial vector current propagators [ΔA3μν(q) and ΔA8μν(q)] to two loops in SU(3)×SU(3) chiral perturbation theory. A large number of O(p6) diverge...
Improved treatment of loop diagrams in SU(3) baryon chiral perturbation theory
Baryon chiral perturbation theory the chiral expansion cycle graph the amount of space
2014/12/22
Baryon chiral perturbation theory as conventionally applied has a well-known problem with the SU(3) chiral expansion in that loop diagrams generate very large SU(3) breaking corrections and greatly up...
The loop-gas approach to Bose-Einstein condensation for trapped particles
Bose - Einstein condensation particles the wave function is symmetrical cellular automata harmonic oscillator
2014/12/22
We examine Bose–Einstein condensation (BEC) for particles trapped in a harmonic potential by considering it as a transition in the length of permutation cycles that arise from wave-function symmetry. ...

2014/12/19
We use analytical arguments and large-scale Monte Carlo calculations to investigate the nature of the phase transitions between distinct complex superfluid phases in a two-component Bose-Einstein cond...
Self inductance of a wire loop as a curve integral
Self inductance of a wire loop curve integral Classical Physics
2012/4/20
It is shown that the self inductance of a wire loop may be written as a curve integral akin to the Neumann formula for the mutual inductance of two wire loops. The only difference is that contribution...
A periodic add/drop system in a fiber ring network was investigated using a reconfigurable optical add/drop multiplexer (ROADM) in a re-circulating fiber loop. After seven cascaded add/drop nodes at e...
Self-injection-locked magnetron as an active ring resonator side coupled to a waveguide with a delayed feedback loop
delayed feedback loop Self-injection-locked
2011/8/26
The theoretical analysis and numerical simulations of the magnetron operation with a feedback loop were performed assuming that the delay of the electromagnetic wave propagating in the loop is constan...
The two-nucleon electromagnetic charge operator in chiral effective field theory ($χ$EFT) up to one loop
electromagnetic charge operator
2011/7/20
The electromagnetic charge operator in a two-nucleon system is derived in chiral effective field theory ($\chi$EFT) up to order $e\, Q$ (or N4LO), where $Q$ denotes the low-momentum scale and $e$ is t...
