Strings in plane-fronted gravitational waves
C. Duval, Z. Horvath, P. A. Horvathy
Brinkmann's plane-fronted gravitational waves with parallel rays --~shortly pp-waves~-- are shown to provide, under suitable conditions, exact string vacua at all orders of the sig…
Hamiltonian aspects of Bogoliubov quasiparticles
Z. Horvath, P. A. Horvathy, L. Martina
The Bogoliubov particle considered in [cond-mat/0507125] admits, contrarily to the claim of the authors, an interesting Hamiltonian structure.
Geometrical Spinoptics and the Optical Hall Effect
Christian Duval, Zalan Horvath, Peter Horvathy
Geometrical optics is extended so as to provide a model for spinning light rays via the coadjoint orbits of the Euclidean group characterized by color and spin. This leads to a the…
Comment on "Berry phase correction to electron density in solids" by Xiao et al
C. Duval, Z. Horvath, P. Horvathy +2
The main result of Xiao et al. [ Phys. Rev. Lett. 95, 137204 (2005)] is shown to follow from Hamiltonian mechanics.
Fermat Principle for spinning light
C. Duval, Z. Horvathy, P. A. Horvathy
Mimicking the description of spinning particles in General Relativity, the Fermat Principle is extended to spinning photons. Linearization of the resulting Papapetrou-Souriau type…
Vanishing of the conformal anomaly for strings in a gravitational wave
C. Duval, Z. Horvath, P. A. Horvathy
Using the non-symmetric-connection approach proposed by Osborn, we demonstrate that, for a bosonic string in a specially chosen plane-fronted gravitational wave and an axion backgr…
