Strong field effects in laser pulses: the Wigner formalism
Strong field effects laser pulses
2010/12/24
We investigate strong field vacuum effects using a phase space approach based on the Wigner formalism. We calculate the Wigner function in a strong null-field background exactly, using lightfront fiel...
The Bargmann-Wigner Formalism for Higher Spins (up to 2)
The Bargmann-Wigner Formalism Higher Spins
2010/12/24
On the basis of our recent modifications of the Dirac formalism we generalize the Bargmann-Wigner formalism for higher spins to be compatible with other formalisms for bosons. Relations with dual elec...
Index Theorem and Overlap Formalism with Naive and Minimally Doubled Fermions
Index Theorem Overlap Formalism Naive
2010/12/24
We present a theoretical foundation for the Index theorem in naive and minimally doubled lattice fermions by studying the spectral flow of a Hermitean version of Dirac operators. We utilize the point...
Weak Measurements Beyond the Aharonov-Albert-Vaidman Formalism
Weak Measurements Aharonov-Albert-Vaidman Formalism
2010/10/29
High-precision experiments via weak measurements require pre-selected and post-selected states (PPS) that are nearly orthogonal, the linear dependence of the measurement outcomes on the weak values qu...
To describe the physical reality, there are two ways of constructing the dynamical equation of field, differential formalism and integral formalism. The importance of this fact is firstly emphasized b...
