A Quantized Spacetime Based on Symmetry
Pisin Chen, Hsu-Wen Chiang, Yao-Chieh Hu
We introduce a new type of the spacetime quantization based on the spinorial description suggested by loop quantum gravity. Specifically, we build our theory on a string theory ins…
Thin-shell instanton tunneling: something-to-something or nothing-to-something?
Pisin Chen, Yao-Chieh Hu, Dong-han Yeom
There exist two interpretations of instantons in the literature. The first interpretation regards instanton as divider between the initial and final hypersurfaces. The Coleman-De L…
Two interpretations of thin-shell instantons
Pisin Chen, Yao-Chieh Hu, Dong-han Yeom
For O(4)-symmetric instantons, there are two complementary interpretations for their analytic continuations. One is the nothing-to-something interpretation, where the initial and f…
Quantization of Spacetime Based on Spacetime Interval Operator
Hsu-Wen Chiang, Yao-Chieh Hu, Pisin Chen
Motivated by both concepts of R.J. Adler's recent work on utilizing Clifford algebra as the linear line element , and the fermionization of…
