... around threshold indicates that the dephasing time due to polariton-polariton scattering is shorter than the polariton lifetime by a factor 2 (not shown). Such a mechanism could indeed permit attainment of internal thermal equilibrium before the escape of polaritons out of the microcavity. The criti ...

Experimental apparatus for overlapping a ground
... The increased appeal of hybrid system stems from the potential benefits of combining the strengths of its composing systems. Trapped ions are leading candidates for the realization of quantum computers [1, 2] and they perform outstandingly as local probes [3, 4, 5, 6] and for quantum meteorology app ...

... Examination of a standing wave suggests that it should be possible to insert another conductor (a conductive wall) at any of the nodes where the tangential electric field is zero without changing a structure of electric field! The applicable boundary condition, therefore, is that the tangential elec ...

We find that at few photon levels, the maximum atomic excitation probability is a monotonic function of photon number for the coherent state pulse, but not for the Fock state pulse. Furth ...

... Laplace’s equation, i.e. ∇2 φ = 0. Since the boundary condition is E1 → 0 for r → ∞, it follows that ∇φ → 0 in that limit. A solution is obviously ∇φ = 0 everywhere. However, according to a well known theorem[1, 2], a solution of Laplace’s equation with specified values of ∇φ on the boundary is uniq ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
