String hypothesis for gl(n|m) spin chains: a particle/hole democracy
String hypothesis gl(n|m) spin chains particle/hole democracy
2011/3/3
This paper is devoted to integrable gl(n|m) spin chains which allow for for-mulation of the string hypothesis. Considering the thermodynamic limit of such spin chains, we derive linear functional equa...
Thermodynamic limit of particle-hole form factors in the massless XXZ Heisenberg chain
Thermodynamic limit particle-hole XXZ Heisenberg chain
2010/4/6
We study the thermodynamic limit of the particle-hole form factors of the XXZ Heisenberg chain in the massless regime. We show that, in this limit, such form factors decrease as an explicitly computed...
Longitudinal Form Factor of Isoscalar Particle-Hole States in 16O, 12C and 40Ca with M3Y Interaction
Longitudinal Form Factors Random Phase Approximation (RPA) Collective Model and M3Y
2010/4/9
Longitudinal form factors of the low-lying, T = 0, particle-hole states of 16O, 12C and 40Ca are studied in the framework of Random Phase Approximation RPA. The basis of single particle states is cons...
