Nonlocality and fluctuations near the optical analog of a sonic horizon
S. Bar-Ad, R. Schilling, V. Fleurov
We consider the behavior of fluctuations near the sonic horizon and the role of the nonlocality of interaction (nonlinearity) on their regularization. The nonlocality dominates if…
Regularization of fluctuations near the sonic horizon due to the quantum potential and its influence on the Hawking radiation
V. Fleurov, R. Schilling
We consider dynamics of fluctuations in transonically accelerating Bose-Einstein condensates and luminous liquids (coherent light propagating in a Kerr nonlinear medium) using the…
Anomalous Thermostat and Intraband Discrete Breathers
S. Aubry, R. Schilling
We investigate the dynamics of a macroscopic system which consists of an anharmonic subsystem embedded in an arbitrary harmonic lattice, including quenched disorder. Elimination of…
Tunneling of a large spin via hyperfine interactions
D. A. Garanin, E. M. Chudnovsky, R. Schilling
We consider a large spin \bf S in the magnetic field parallel to the uniaxial crystal field, interacting with N >> 1 nuclear spins \bf I_i via Hamiltonian \cal H = -DS_z^2 - H_zS_z…
