Exclusion statistics for quantum Hall states in Tao-Thouless limit
quantum Hall states Tao-Thouless limit
2010/11/19
We consider spin-polarized abelian quantum Hall states in the Tao-Thouless limit, ie on a thin
torus. For any filling factor = p/q a well-defined sector of low-energy states is dentified and the ex...
Conductance through quantum wires with Levy-type disorder: universal statistics in anomalous quantum transport
Conductance through quantum wires Levy-type disorder anomalous quantum transport
2010/11/23
Random processes characterized by density probabilities with a long tail–L´evy-type
processes– have been found in very different phenomena and fields such as biology, economy, and physics.
The Schrödinger equation for the evolution of isolated quantum systems determines the constants
of motion for the dynamical problem, which can be identified with the populations along the
princ...
Quantum Dynamics Arising from Statistical Axioms
Quantum Dynamics Arising Statistical Axioms
2010/10/20
We investigate the dynamics of pairs of Fermions and Bosons released from a box and find that their populations have unique generic properties ensuing from the axioms of quantum statistics and symmetr...
Exact Pointer Properties for Quantum System Projector Measurements with Application to Weak Measurements and Their Accuracy
Exact Pointer Properties Quantum System Projector Measurements Application Measurements Accuracy
2010/11/5
Exact pointer states are obtained for projection operator measurements performed upon pre-selected (PS) and upon pre- and post-selected (PPS) quantum systems. These states are used to provide simple e...
Can Many-Worlds Survive a Quantum Doomsday
interpretation quantum mechanics problem probability quantum suicide
2011/9/7
A novel puzzle for the notion of probability in the Many-Worlds interpretation of quantum mechanics is presented. The puzzle makes use of a thought experiment that some have claimed would provide empi...
We present the elements of a new approach to the foundations of quantum theory and information theory which is based on the algebraic approach to integration, information geometry, and maximum relativ...
Quantum entanglement and entropy in particle creation
Quantum entanglement particle creation entropy
2010/3/18
We investigate the basic theoretical issues in the quantum entanglement of particle pairs created from the vacuum in a time-dependent background field or spacetime. Similar to entropy generation from ...
We illustrate the crucial role played by decoherence (consistency of quantum histories) in extracting consistent quantum probabilities for alternative histories in quantum cosmology. Specifically, wit...
Effects of interference in the dynamics of spin-1/2 transverse XY Chain driven periodically through quantum critical points
Effects of interference dynamics of spin-1/2 transverse XY Chain quantum critical points
2010/4/13
We study the effects of interference on the quenching dynamics of a one-dimensional spin 1/2 $XY$ model in the presence of a transverse field ($h(t)$) which varies sinusoidally with time as $h = h_0\c...

Stability Analysis a Three-Stream Quantum-Plasma Equilibrium
2010/10/27
We apply the Nyquist method to analyze the stability of small amplitude electrostatic waves in quantum plasmas described by the Wigner-Poisson system. The technique is presented in detail to assess th...
Introduction to Quantum Monte Carlo Simulations for Fermionic Systems
Quantum Monte Carlo Fermionic Systems
2010/10/27
We tutorially review the determinantal Quantum Monte Carlo method for fermionic systems, using the Hubbard model as a case study. Starting with the basic ingredients of Monte Carlo simulations for cla...
