Modular Invariants and Fischer-Griess Monster
Marcin Jankiewicz, Thomas W. Kephart
We show interesting relations between extremal partition functions of a family of conformal field theories and dimensions of the irreducible representations of the Fischer-Griess M…
Black Holes and Generalized Scalar Field
Marcin Jankiewicz, Anjan A. Sen
We study the possibility of occurrence of scalar hair with a non-canonical kinetic term for a static, spherically symmetric asymptotically flat black hole spacetime. We first obtai…
Extension of Monster Moonshine to c=24k Conformal Field Theories
Marcin Jankiewicz, Thomas W. Kephart
We present a family of conformal field theories (or candidates for CFTs) that is build on extremal partition functions. Spectra of these theories can be decomposed into the irreduc…
Long-Wavelength Modes of Cosmological Scalar Fields
Marcin Jankiewicz, Thomas W. Kephart
We give a numerical analysis of long-wavelength modes in the WKB approximation of cosmological scalar fields coupled to gravity via . Massless fields are coupled conformal…
Transformations among large c conformal field theories
Marcin M. Jankiewicz, Thomas W. Kephart
We show that there is a set of transformations that relates all of the 24 dimensional even self-dual (Niemeier) lattices, and also leads to non-lattice objects that however cannot…
Space-Time Foam and Cosmic-Ray Interactions
Marcin M. Jankiewicz, Roman V. Buniy, Thomas W. Kephart +1
It has been proposed that propagation of cosmic rays at extreme-energy may be sensitive to Lorentz-violating metric fluctuations (``foam''). We investigate the changes in interacti…
