Kippenberg Optical frequency combs, which constitute equally spaced frequency lines, can be generated using temporal dissipative Kerr solitons—stable laser pulses generated in a laser-driven nonlinear microresonator—but these solitons can destabilize and oscillate. A new analysis reveals a novel mechanism that can trigger “soliton breathing,” highlighting the rich nonlinear dynamics of dissipative temporal structures in microresonators and identifying a regime that has to be avoided in applications.

Spin-entanglement between two freely propagating electrons: Experiment and theory (2017)

Beschreibung: Author(s): D. Vasilyev, F. O. Schumann, F. Giebels, H. Gollisch, J. Kirschner, and R. Feder Here, the authors make connection to the foundation of quantum mechanics. As stated by Schrquotodinger, entanglement is “the characteristic trait of quantum mechanics” and seemingly at odds with the description of nature. In this joint experimental and theoretical work, the authors discuss the possibility of spin entanglement of two freely propagating electrons. These have been created by a collision of a spin-polarized primary electron with the Shockley surface state of the Cu(111) surface. The contribution of this state can clearly be identified in the experiment and allows use of its particular features. The electron scattering study done here resembles the scenario envisioned by the seminal works of Einstein-Podolsky-Rosen and Schrquotodinger to work out the peculiar nature of entanglement. [Phys.

Chigrinov, Shuangchun Wen, and Hoi-Sing Kwok In an optical vortex beam, each photon carries orbital angular momentum (OAM), a useful resource for applications in optical communication and quantum information processing. The authors demonstrate a diffractive bifocal vortex lens that generates and sorts light beams of different OAM, by means of polarization control. Placing the lens inside a cavity, a vortex-beam laser with a chosen OAM can be realized. Moreover, the lens’s OAM sorting can be used in a multifocal optical-trapping system that facilitates the manipulation of nanoparticles, molecules, and biological samples. [Phys. Rev.

Vázquez-Hernández Violation of C P invariance is a quite relevant phenomenon that is found in the Standard Model, though in small amounts. This has been an incentive to look for high-energy descriptions in which C P violation is increased, thus enhancing effects that are suppressed in the Standard Model, such as the el… [Phys. Rev.

Beschreibung: Author(s): Mark P. Hertzberg and Frank Wilczek We examine the hypothesis that inflation is primarily driven by vacuum energy at a scale indicated by gauge coupling unification. Concretely, we consider a class of hybrid inflation models wherein the vacuum energy associated with a grand unified theory condensate provides the dominant energy during… [Phys. Rev.
