Spontaneous symmetry breaking of (1+1)-dimensional phi4 theory in light-front field theory. III.
We investigate (1+1)-dimensional φ4 field theory in the symmetric and broken phases using discrete light-front quantization. We calculate the perturbative solution of the zero-mode constraint equation for both the symmetric and broken phases and show that standard renormalization of the theory yields finite results. We study the perturbative zero-mode contribution to two diagrams and show that ...
متن کاملNon-Gaussian Fixed Point in Four-Dimensional Pure Compact U(1) Gauge Theory on the Lattice.
The line of phase transitions, separating the confinement and the Coulomb phases in the four-dimensional pure compact U(1) gauge theory with extended Wilson action, is reconsidered. We present new numerical evidence that a part of this line, including the original Wil-son action, is of second order. By means of a high precision simulation on homogeneous lattices on a sphere we find that along t...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

We discuss spontaneous symmetry breaking of (1+1)-dimensional φ theory in light-front field theory using a Tamm-Dancoff truncation. We show that, even though light-front field theory has a simple vacuum state which is an eigenstate of the full Hamiltonian, the field can develop a nonzero vacuum expectation value. This occurs because the zero mode of the field must satisfy an operator valued con...
متن کاملFour-dimensional N = 1 Supersymmetric Yang-mills Theory on the Lattice without Fine-tuning
We propose a method to formulate four-dimensional N = 1 super Yang-Mills theory on the lattice without ne-tuning. We rst show that four-dimensional Weyl fermion in a real representation, which is equivalent to Majorana fermion, can be formulated using the domain wall approach with an addition of a Majorana mass term only for the unwanted mirror fermion. This formalism has manifest gauge invaria...
