Towards elucidation of zero-temperature criticality of Ising model on 2d DT
Jan Ambjørn, Yuki Sato, Tomo Tanaka
We study the zero-temperature criticality of the Ising model on two-dimensional dynamical triangulations to contemplate its physics. As it turns out, an inhomogeneous nature of the…
Criticality at absolute zero from Ising model on two-dimensional dynamical triangulations
Yuki Sato, Tomo Tanaka
We reconsider the criticality of the Ising model on two-dimensional dynamical triangulations based on the hermitian two-matrix model with the introduction of a loop-co…
Discretisation parameter and operator ordering in loop quantum cosmology with the cosmological constant
Tomo Tanaka, Fumitoshi Amemiya, Masahiro Shimano +2
In loop quantum cosmology, the Hamiltonian reduces to a finite difference operator. We study the initial singularity and the large volume limit against the ambiguities in the discr…
Black hole entropy for the general area spectrum
Tomo Tanaka, Takashi Tamaki
We consider the possibility that the horizon area is expressed by the general area spectrum in loop quantum gravity and calculate the black hole entropy by counting the degrees of…
