CDT and Horava-Lifshitz QG in Two Dimensions

Yuki Sato

The two-dimensional causal dynamical triangulations (d CDT) is a lattice model of quantum geometry. In d CDT, one can deal with the quantum effects analytically and explore t…

Tensor network approach to 2d Lorentzian quantum Regge calculus

Yoshiyasu Ito, Daisuke Kadoh, Yuki Sato

We demonstrate a tensor renormalization group (TRG) calculation for a two-dimensional Lorentzian model of quantum Regge calculus (QRC). This model is expressed in terms of a tensor…

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…
