Parity proofs of the Bell-Kochen-Specker theorem based on the 600-cell

Mordecai Waegell, P. K. Aravind, Norman D. Megill +1

The set of 60 real rays in four dimensions derived from the vertices of a 600-cell is shown to possess numerous subsets of rays and bases that provide basis-critical parity proofs…

Kochen-Specker Sets and Generalized Orthoarguesian Equations

Norman D. Megill, Mladen Pavicic

Every set (finite or infinite) of quantum vectors (states) satisfies generalized orthoarguesian equations (OA). We consider two 3-dim Kochen-Specker (KS) sets of vectors and sho…

New Class of 4-Dim Kochen-Specker Sets

Mladen Pavicic, Norman D. Megill, P. K. Aravind +1

We find a new highly symmetrical and very numerous class (millions of non-isomorphic sets) of 4-dim Kochen-Specker (KS) vector sets. Due to the nature of their geometrical symmetri…

Graph Approach to Quantum Systems

Mladen Pavicic, Brendan D. McKay, Norman D. Megill +1

Using a graph approach to quantum systems, we prove that descriptions of 3-dim Kochen-Specker (KS) setups as well as descriptions of 3-dim spin systems by means of Greechie lattice…

Optical Superradiance from Nuclear Spin Environment of Single Photon Emitters

E. M. Kessler, S. Yelin, M. D. Lukin +2

We show that superradiant optical emission can be observed from the polarized nuclear spin ensemble surrounding a single photon emitter such as a single quantum dot (QD) or Nitroge…

Quantum dynamics in the bosonic Josephson junction

Maya Chuchem, Katrina Smith-Mannschott, Moritz Hiller +3

We employ a semiclassical picture to study dynamics in a bosonic Josephson junction with various initial conditions. Phase-diffusion of coherent preparations in the Josephson regim…
