Wormhole interaction in 2d Horava-Lifshitz quantum gravity
Jan Ambjørn, Yuki Hiraga, Yoshiyasu Ito +1
A lattice regularization for the d projectable Horava-Lifshitz (HL) quantum gravity is known to be the d causal dynamical triangulations (CDT), and the d CDT can be genera…
Unusual high-field metal in a Kondo insulator
Ziji Xiang, Lu Chen, Kuan-Wen Chen +11
Within condensed-matter systems, strong electronic interactions often lead to exotic quantum phases. A recent manifestation of this is the unexpected observation of magnetic quantu…
Wormholes in 2d Horava-Lifshitz quantum gravity
Jan Ambjorn, Yuki Hiraga, Yoshiyasu Ito +1
We quantize the two-dimensional projectable Horava-Lifshitz gravity with a bi-local as well as space-like wormhole interaction. The resulting quantum Hamiltonian coincides with the…
Wormholes, a fluctuating cosmological constant and the Coleman mechanism
Jan Ambjorn, Yuki Sato, Yoshiyuki Watabiki
We show that in a two-dimensional model of quantum gravity the summation over all possible wormhole configurations leads to a kind of Coleman mechanism where the cosmological const…
