The Light-Cone Gauge without Prescriptions
, 1999
"... Feynman integrals in the physical light-cone gauge are more difficult to solve than their covariant counterparts. The difficulty is associated with the presence of unphysical singu-larities due to the inherent residual gauge freedom in the intermediate boson propagators constrained within this gauge ..."

QUANTUM DILATON GRAVITY IN THE LIGHT–CONE GAUGE
, 1992
"... Recently, models of two-dimensional dilaton gravity have been shown to admit classical black-hole solutions that exhibit Hawking radiation at the semi-classical level. These classical and semi-classical analyses have been performed in conformal gauge. We show in this paper that a similar analysis in ..."

in the light–cone gauge leads to the same results. Moreover, quantization of matter fields in light–cone gauge can be naturally extended to include quantizing the metric field à la KPZ. We argue that this may provide a new framework to address many issues associated to black-hole physics. ⋆ Work supported

The Schwinger Model in Light-Cone Gauge
, 1997
"... The Schwinger model, defined in the space interval −L ≤ x ≤ L, with (anti)periodic boundary conditions, is canonically quantized in the lightcone gauge A − = 0 by means of equal-time (anti)commutation relations. The transformation diagonalizing the complete Hamiltonian is explicitly constructed, th ..."

Light-cone gauge quantization of string theories
- on ADS3 space, hep-th/9812216, Nucl. Phys. B551
, 1999
"... Light-cone gauge quantization procedures are given, for superstring theory on AdS3 space charged with NS-NS background, both in NSR and GS formalism. The spacetime (super)conformal algebras are constructed in terms of the transversal physical degrees of freedom. The spacetime conformal anomaly agree ..."

Propagators with the Mandelstam-Leibbrandt Prescription in the Light-Cone Gauge
, 2004
"... We show that the Feynman propagator in the light-cone gauge with the Mandelstam-Leibbrandt prescription has a logarithmic growth for large ñ · x which is related to the presence of a residual gauge invariance. Furthermore, we show that the retarded propagator for the ñ · A component of the gauge fie ..."

New Prescription in light-cone gauge theories
, 1995
"... New prescription for the singularities of light-cone gauge theories is suggested. The new prescription provides Green’s function which is identical with and different from that of Mandelstam-Leibbrandt prescription at d = 4 and d = 2 respectively. 1 The light-cone gauge(radiation gauge in light-cone ..."

D-branes in the light-cone gauge and broken symmetries
, 1996
"... Boundary states for D-branes are constructed using the light cone gauge. The D-brane breaks half the spacetime supersymmetry giving rise to fermionic zero modes living on the brane. The nonlinear realization of the broken supersymmetry on the open string degrees of freedom is analysed and the influe ..."

Light-Cone Gauge for 1+1 Strings ∗
, 1991
"... Explicit construction of the light-cone gauge quantum theory of bosonic strings in 1+1 spacetime dimensions reveals unexpected structures. One is the existence of a gauge choice that gives a free action at the price of propagating ghosts and a nontrivial BRST charge. Fixing this gauge leaves a U(1) ..."
