Abstract:
We introduce a uniform light-cone gauge for strings propagating in AdS5 ?S5
space-time. We use the gauge to analyze strings from the su(1|1) sector, and show that
the reduced model is described by a quadratic action for two complex fermions. Thus, the
uniform light-cone gauge allows us to solve the model exactly. We analyze the near BMN
spectrum of states from the su(1|1) sector and show that it correctly reproduces the 1/J
corrections. We also compute the spectrum in the strong coupling limit, and derive the
famous ?1/4 asymptotics. We then show that the same string spectrum can be also derived
by solving Bethe ansatz type equations, and discuss their relation to the quantum string
Bethe ansatz for the su(1|1) sector.
