Hamiltonians and physical vacua of exactly solvable models
Lubomir Martinovic
Correct quantum Hamiltonians of a few exactly solvable models in two space-time dimensions are derived by taking into account operator solutions of the field equations. While two v…
Higgs mechanism in a light front formulation
Lubomir Martinovic, Pierre Grange
We give a simple derivation of the Higgs mechanism in an abelian light front field theory. It is based on a finite volume quantization with antiperiodic scalar fields and a periodi…
Analytic solution of the microcausality problem in Discretized Light Cone Quantization
Lubomir Martinovic, Marshall Luban
It is shown that that violation of causality in two-dimensional light-front field theories quantized in a finite ``volume'' with periodic or antiperiodic boundary conditions is…
Ab initio results for the broken phase of scalar light front field theory
Dipankar Chakrabarti, A. Harindranath, Lubomir Martinovic +2
We present nonperturbative light-front energy eigenstates in the broken phase of a two dimensional quantum field theory using Discrete Light Cone Quantization and e…
Kinks in Discrete Light Cone Quantization
Dipankar Chakrabarti, A. Harindranath, Lubomir Martinovic +1
We investigate non-trivial topological structures in Discrete Light Cone Quantization (DLCQ) through the example of the broken symmetry phase of the two dimensional theory us…
