PIRSA:16060065  ( MP4 Medium Res , MP3 , PDF ) Which Format?
A Final Boundary Condition: Several Implications for the Universe
Speaker(s): Eliahu Cohen
Abstract: In classical mechanics, only the initial state of the system is needed to determine its time evolution. Additional information on the final state is either redundant or inconsistent. In quantum mechanics, however, the initial state does not convey all measurements’ outcomes. Only when augmented wi... read more

PIRSA:16060067  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Instability of Flatspace and the Early Quantum Fluctuations by Considering an Unbounded Hamiltonian
Speaker(s): Ali Nayeri
Abstract: Introducing a new field which makes the Hamiltonian unbounded, we show that vacuum fluctuations of a scalar field destabilized the flatspace. Perturbation in this new scalar field, may also explain some astrophysical phenomena in the galactic scale.

PIRSA:16060068  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Atomic two-qubit quantum operations with ancillary multiphoton states
Abstract: We propose and theoretically investigate the implementation of entangling operations on two two-level atoms using cavity-QED scenarios. The atoms interact with an optical cavity and their state is postselected in a noninvasive way by measuring the optical field after the interaction. We show that th... read more

Finally making sense of Quantum Mechanics, part 5
Speaker(s): Yakir Aharonov
Abstract:

PIRSA:16060071  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Quantum paradoxes emerging in matter-wave interferometer experiments
Speaker(s): Yuji Hasegawa
Abstract: Peculiarities of quantum mechanical predictions on a fundamental level are investigated intensively in matter-wave optical setups; in particular, neutron interferometric strategy has been providing almost ideal experimental circumstances for experimental demonstrations of quantum effects. In this de... read more

PIRSA:16060073  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Why interactions matter: How the laws of dynamics determine the shape of physical reality
Speaker(s): Holger Hofmann
Abstract: Measurements performed at variable strengths show that non-commuting physical properties are related by complex-valued statistics, where the complex phase expresses the action of transformations along orbits represented by the eigenstates. In strong measurements, the dynamics along the orbits is com... read more
