What is the B mode in CMB polarization?
Jack Kwok, King Lau, Edward Young +1
A linear polarization field on a surface is expressed in terms of scalar functions, providing an invariant separation into two components; one of these is the B mode, important as…
Eigenvector Expansion and Petermann Factor for Ohmically Damped Oscillators
Alec Maassen van den Brink, K. Young, M. H. Yung
Correlation functions in ohmically damped systems such as coupled harmonic oscillators or optical resonators can be expressed as a single sum over modes …
Linearized Perturbations of a Black Hole: Continuum Spectrum
P. T. Leung, Alec Maassen_van_den_Brink, K. W. Mak +1
Linearized perturbations of a Schwarzschild black hole are described, for each angular momentum , by the well-studied discrete quasinormal modes (QNMs), and in addition a con…
Unconventional Gravitational Excitation of a Schwarzschild Black Hole
P. T. Leung, Alec Maassen van den Brink, K. W. Mak +1
Besides the well-known quasinormal modes, the gravitational spectrum of a Schwarzschild black hole also has a continuum part on the negative imaginary frequency axis. The latter is…
Hamiltonian and Linear-Space Structure for Damped Oscillators: II. Critical Points
S. C. Chee, Alec Maassen van den Brink, K. Young
The eigenvector expansion developed in the preceding paper for a system of damped linear oscillators is extended to critical points, where eigenvectors merge and the time-evolution…
Hamiltonian and Linear-Space Structure for Damped Oscillators: I. General Theory
S. C. Chee, Alec Maassen van den Brink, K. Young
The phase space of damped linear oscillators is endowed with a bilinear map under which the evolution operator is symmetric. This analog of self-adjointness allows properties f…
