“…One of the most promising quantum simulators is the cold atom system since the realization of condensation of bosonic atoms [14,15] and fermionic atom pairs [16,17] has led to numerous advances with applications in coherent manipulation of neutral atoms, such as creating cold molecules in quantum chemistry (see the reviews [18,19] and the references therein). Ultracold neutral atoms in OLs are quite suited for mimicking condensed-matter physics [20,21], and may shew new light on strongly correlated state problems like high-temperature superconductivity [22], fractional quantum Hall effect [23,24], and the quantum magnetism [25].…”

Quantum simulation is a powerful tool to study a variety of problems in physics, ranging from high-energy physics to condensed-matter physics. In this article, we review the recent theoretical and experimental progress in quantum simulation of Dirac equation with tunable parameters by using ultracold neutral atoms trapped in optical lattices or subject to light-induced synthetic gauge fields. The effective theories for the quasiparticles become relativistic under certain conditions in these systems, making them ideal platforms for studying the exotic relativistic effects. We focus on the realization of one, two, and three dimensional Dirac equations as well as the detection of some relativistic effects, including particularly the well-known Zitterbewegung effect and Klein tunneling. The realization of quantum anomalous Hall effects is also briefly discussed.

When we look at todays Physics, we can only be impressed by an enormous amount of knowledge and a complete New World of technical applications that has never been in the world before. We now live in the century of the impressive victory of the new science and the new technology over the old-fashioned world and the old-fashioned way of thinking. Great changings in the way of thinking and the technological achievements are mostly characterized by an important scientific publication in a century that changes everything in that century. We can recognize the century of Isaac Newton who triggered in 1687 the large changings in thinking with his famous publication “Philisophiae Naturalis Principia Mathematica” (Mathematical Principles of Natural Philosophy).We recognize the century of James Clerk Maxwell who triggered in 1865 the large changings in thinking with his famous publication “A Dynamical Theory of the Electromagnetic Field”.We recognize the century of Albert Einstein who triggered in 1905 the large changings in thinking with his famous theory of Special Relativity represented in his publication “On the Electrodynamics of Moving Bodies”. Manifesting a “New Theory” and a “New Way of Thinking” with important contributions of Hendrik Lorentz, Henri Poincaré and Hermann Minkowski.It is recognizable that with the suddenly changing in thinking in a new period, a new kind of mutual common sense and a general agreement by many scientists of the the new theory and the new way of thinking rises. The new theory becomes like a medieval town with a large high wall around it. The New Theory will be protected by common sense and mutual agreement. In Maxwell’s time there were no optical LASERS (Light Amplification by Stimulated Emission of Radiation) and the outcome of his theory was in his time completely in correspondence with what could be measured at that time. The value for the speed of light, calculated from the Maxwell Equations, corresponded almost exactly with the value for the speed of light measured in 1862 by Léon Foucault by a system of rotating mirrors and measured in 1877 by Albert Michelson (300.140 [km/s]). But nowadays there rise several problems with Maxwell’s theory for the electromagnetic field. Since the existence of the LASERS it became clear that the speed of light is not always the same in every direction. When a beam of light, generated by a LASER, propagates with the well-known speed of light “c = 299.792 [km/s]” in the z-direction, the speed of light equals zero in the x-direction and the y-direction (in a orthogonal x,y,z frame).This new phenomenon cannot be explained by Maxwell’s Theory. In Maxwell’s Theory the speed of light has to be exactly the same in every direction. This is clearly not the fact for a LASER beam. And also for the projection of a slide on a screen, it is clearly that the speed of light within the plane of the screen equals zero. Because the slide we observe does not move. While the projection beam itself moves towards the screen with the speed of light “c”, the beam clearly remains focused and does not move within the plane, perpendicular to the direction of propagation. There is no other conclusion than the conclusion that the Maxwell Equations are “wrong” or at least “not complete”. The right equation(s) have to describe both possibilities. The possibility that the light moves in every direction with the exactly the same speed of light “c” like the light being emitted by the sun. And the possibility that the light moves only in one direction and equals zero in the directions perpendicular to the plane of propagation like the propagation of a LASER beam.

The Light we see in our daily world has the Power to open Doors that have never been openened before.Albert Einstein, Lorentz and Minkowski published together in 1905 the Theory of Special Relativity and Einstein published in 1915 his field theory of general relativity based on a curved 4-dimensional space-time continuum to integrate the gravitational field and the electromagnetic field in one unified field. Since then the method of Einstein’s unifying field theory has been developed by many others in more than 4 dimensions resulting finally in the well-known 10-dimensional and 11-dimensional “string theory”. String theory is an outgrowth of S-matrix theory, a research program begun by Werner Heisenberg in 1943 (following John Archibald Wheelers 1937 introduction of the S-matrix), picked up and advocated by many prominent theorists starting in the late 1950’s.Theodor Franz Eduard Kaluza (1885-1954), was a German mathematician and physicist well-known for the Kaluza–Klein theory involving field equations in curved five-dimensional space. His idea that fundamental forces can be unified by introducing additional dimensions re-emerged much later in the “String Theory”.The original Kaluza-Klein theory was one of the first attempts to create an unified field theory i.e. the theory, which would unify all the forces under one fundamental law. It was published in 1921 by Theodor Kaluza and extended in 1926 by Oskar Klein. The basic idea of this theory was to postulate one extra compactified space dimension and introduce nothing but pure gravity in a new (1 + 4)-dimensional space-time. Klein suggested that the fifth dimension would be rolled up into a tiny, compact loop on the order of 10-35 [m]The "New Theory" represents the "4-dimensional Unification of De Broglie Waves and Electromagnetic Waves". The "New Theory" demonstrates that the propagation of light is fully consistent with Newton's famous 3 laws of motion. That the speed of light is fully controlled by a prefect equilibrium between the inertia of the electromagnetic radiation energy (electromagnetic mass) and the electromagnetic "Radiation Pressure" at the front of the "Beam of Light". That, in the application of a laser beam, the outward oriented radiation pressure at the sides of the laser beam has been fully compensated by the inward oriented forces of electromagnetic interaction according Newton’s third law "Action = Reaction".
