The signatures of Majorana zero-energy mode leaking into a spin-charge entangled double quantum dot are investigated theoretically in the strong electron correlation regime. considered setup consists two capacitively coupled dots attached to external contacts and side-attached topological superconducting wire hosting quasiparticles. We show that presence gives rise unique features local density...

A series of lectures are given to discuss the zero-mode problem on the light-front (LF) quantization with special emphasis on the peculiar realization of the trivial vacuum, the spontaneous symmetry breaking (SSB) and the Lorentz invariance. We first identify the zero-mode problem on the LF. We then discuss Discrete Light-Cone Quantization (DLCQ) which was first introduced by Maskawa and Yamawa...

We calculate the effective Lagrangian for a magnetic field in spinor, scalar and vector QED. Connections are then made to SU(NC) Yang–Mills theory and QCD. The magnetization and the corresponding effective charge are obtained from the effective Lagrangian. The renormalized vacuum magnetization will depend on the renormalization scale chosen. In the absence of any natural scale, it is thus of li...
