Inflation Model Based on Virasoro Squeezing
Kenji Ebata, So Katagiri, Yoshiki Matsuoka +2
We propose a novel mechanism for realizing slow-roll inflation that is fully consistent with observational data, based on conformal transformations acting exclusively on a complex…
A Lorentz Covariant Matrix Model for Bosonic M2-Branes: Nambu Brackets and Restricted Volume-Preserving Deformations
So Katagiri
We propose a Lorentz covariant matrix model as a nonperturbative formulation of the bosonic M2-brane in M-theory. Unlike previous approaches relying on the light-cone gauge or symm…
Quantization of Nambu Brackets from Operator Formalism in Classical Mechanics
So Katagiri
This paper proposes a novel approach to quantizing Nambu brackets in classical mechanics using operator formalism. The approach employs the ``Planck derivative'' to represent Nambu…
Beyond Squeezing à la Virasoro Algebra
So Katagiri, Akio Sugamoto, Koichiro Yamaguchi +1
The generalization of squeezing is realized in terms of the Virasoro algebra. The higher-order squeezing can be introduced through the higher-order time-dependent potential, in whi…
Gravity Analog Model of Non-equilibrium Thermodynamics
Noriaki Aibara, Naoaki Fujimoto, So Katagiri +4
Non-equilibrium thermodynamics of Onsager and Machlup and of Hashitsume is reformulated as a gravity analog model, in which thermodynamic variables, kinetic coefficients and genera…
D3-brane from D-instantons in the hybrid formalism of superstring
Yoshiteru Amemiya, Kenji Araki, So Katagiri
A Dp-brane can be regarded as a configuration of infinitely many D(p-2k)-branes in bosonic string. We will show this property of D-branes in the superstring case using the hybrid f…
