Is There an Information-Loss Problem for Black Holes?,nto a thermal state (‘information-loss problem’). Here it is argued that the whole evolution is unitary and that the thermal nature of Hawking radiation emerges solely through decoherence – the irreversible interaction with further degrees of freedom. For this purpose a detailed comparison with an a

Tentative answers are suggested by a model of geometrodynamics based on the statistical concepts of entropy, information geometr

Probability of Intrinsic Time-Arrow from Information Loss, the given system. When the information loss tends to zero the intrinsic time-arrow becomes uncertain. We propose the heuristic relationship 1/[1+exp(-.) for the probability of the intrinsic time-arrow. The main parts of the present work are trying to confirm this heuristic equation..The probability

Dissipation, Emergent Quantization, and Quantum Fluctuations,f the path integral formulation of the quantum Brownian motion problem developed by Schwinger and by Feynman and Vernon. The doubling of the phase space degrees of freedom for dissipative systems and thermal field theories is discussed and the doubled variables are related to quantum noise effects.

Decoherence and Quantum Trajectories,ul technique by which decohering systems can be resolved into stochastic evolutions, conditioned on different possible “measurements” of the environment. By calling on recently-developed tools from quantum information theory, we can analyze simplified models of decoherence, explicitly quantifying th
