Braided Categorical Quantum Mechanics I
Spencer D. Stirling, Yong-Shi Wu
This is the first paper in a series where we generalize the Categorical Quantum Mechanics program (due to Abramsky, Coecke, et al) to braided systems. In our view a uniform descrip…
Preparation of atomic Fock states by trap reduction
M. Pons, A. del Campo, J. G. Muga +1
We describe the preparation of atom-number states with strongly interacting bosons in one dimension, or spin-polarized fermions. The procedure is based on a combination of weakenin…
Unital Positive Maps and Quantum States
M. Asorey, A. Kossakowski, G. Marmo +1
We analyze the structure of the subset of states generated by unital completely positive quantum maps, A witness that certifies that a state does not belong to the subset generated…
Quantal time asymmetry: mathematical foundation and physical interpretation
A. Bohm, P. Bryant, Y. Sato
For a quantum theory that includes exponentially decaying states and Breit-Wigner resonances, which are related to each other by the lifetime-width relation , wher…
Real-time control of the periodicity of a standing wave: an optical accordion
T. C. Li, H. Kelkar, D. Medellin +1
We report an experimental method to create optical lattices with real-time control of their periodicity. We demonstrate a continuous change of the lattice periodicity from 0.96 …
f-oscillators deformation for Moyal algebras
V. I. Man'ko, G. Marmo, E. C. G. Sudarshan +1
Using general construction of star-product the q-deformed Wigner-Weyl-Moyal quantization procedure is elaborated. The q-deformed Groenewold kernel determining the product of quantu…
