Coherent states over Grassmann manifolds and the WKB-exactness in path integral
Kazuyuki Fujii, Taro Kashiwa, Seiji Sakoda
\(\Un{N}\) coherent states over Grassmann manifold, \(\grsmn{N}{n}\simeq\Un{N}/ (\Un{n}\times \Un{N-n})\), are formulated to be able to argue the WKB-exactness, so called the local…

1+1 dimensional QCD with fundamental bosons and fermions
Kenichiro Aoki, Tomoyasu Ichihara
We analyze the properties of mesons in 1+1 dimensional QCD with bosonic and fermionic ``quarks'' in the large $\nc$ limit. We study the spectrum in detail and show that it is impos…

More about Path Integral for Spin
Kunio Funahashi, Taro Kashiwa, Shuji Nima +1
Path integral for the spin system is reconsidered. We show that the Nielsen-Rohrlich(NR) formula is equivalent to the spin coherent state expression so that the phase space…
