Quantum effects of stringy and membranic nature for the swimming of micro-organisms in a fluid
E. Elizalde, M. Kawamura, S. Nojiri +2
The static potential is investigated in string and membrane theories coupled to gauge fields (specifically, external magnetic fields) and with antisymmetric tensor fields. T…
Collective Motion of Micro-organisms from Field Theoretical Viewpoint
Shin'ichi Nojiri, Masako Kawamura, Akio Sugamoto
We analyze the collective motion of micro-organisms in the fluid and consider the problem of the red tide. The red tide is produced by the condensation of the micro-organisms, whic…
Two-Form Gravity and the Generation of Space-Time
Miyuki KATSUKI, Shin'ichi NOJIRI, Akio SUGAMOTO
In the framework of the two-form gravity, which is classically equivalent to the Einstein gravity, the one-loop effective potential for the conformal factor of metric is calculated…
Is the Condensation of Strings the Origin of Einstein Gravity ?
Miyuki KATSUKI, Hiroto KUBOTANI, Shin'ichi NOJIRI +1
A mechanism of generating the metric is proposed, where the Kalb-Ramond symmetry existing in the topological BF theory is broken through the condensation of the string fields which…
