BRST structure of non-linear superalgebras
M. Asorey, P. M. Lavrov, O. V. Radchenko +1
In this paper we analyse the structure of the BRST charge of nonlinear superalgebras. We consider quadratic non-linear superalgebras where a commutator (in terms of (super) Poisson…
Loewner equations, Hirota equations and reductions of universal Whitham hierarchy
Kanehisa Takasaki, Takashi Takebe
This paper reconsiders finite variable reductions of the universal Whitham hierarchy of genus zero in the perspective of dispersionless Hirota equations. In the case of one-variabl…
An algebraic derivation of the eigenspaces associated with an Ising-like spectrum of the superintegrable chiral Potts model
Akinori Nishino, Tetsuo Deguchi
In terms of the loop algebra and the algebraic Bethe-ansatz method, we derive the invariant subspace associated with a given Ising-like spectrum consisting of $…
Development of signal-extraction scheme for Resonant Sideband Extraction
K. Kokeyama, K. Somiya, F. Kawazoe +3
As a future plan, an advanced gravitational-wave detector will employ an optical configuration of resonant sideband extraction (RSE), achieved with an additional mirror at the sign…
Classical no-cloning theorem under Liouville dynamics by non-Csiszár f-divergence
T. Yamano, O. Iguchi
The Csiszár f-divergence, which is a class of information distances, is known to offer a useful tool for analysing the classical counterpart of the cloning operations that are quan…
A String Field Theory based on Causal Dynamical Triangulations
J. Ambjorn, R. Loll, Y. Watabiki +2
We formulate the string field theory in zero-dimensional target space corresponding to the two-dimensional quantum gravity theory defined through Causal Dynamical Triangulations. T…
