A mechanism of the large-scale damping in the CMB anisotropy
Masafumi Fukuma, Yuji Kono, Akitsugu Miwa
We present a mechanism through which a certain class of short-distance cutoff affects the CMB anisotropies at large angular scales. Our analysis is performed in two steps. The firs…
Effects of space-time noncommutativity on the angular power spectrum of the CMB
Masafumi Fukuma, Yuji Kono, Akitsugu Miwa
We investigate an inflationary model of the universe based on the assumption that space-time is noncommutative in the very early universe. We analyze the effects of space-time nonc…
Holographic entropy bound in two-dimensional gravity
Masafumi Fukuma, Akitsugu Miwa, Kazuyoshi Takahashi
Bousso's entropy bound for two-dimensional gravity is investigated in the lightcone gauge. It is shown that due to the Weyl anomaly, the null component of the energy-momentum tenso…
