Superfluid Interfaces in Quantum Solids
Die the moment of inertia microcrystalline superfluid state quantum solid superfluid state
2014/12/20
One scenario for the nonclassical moment of inertia of solid 4He discovered by Kim and Chan [Nature (London) 427, 225 (2004)] is the superfluidity of microcrystallite interfaces. On the basis of the m...
Decoherence and quantum walks: Anomalous diffusion and ballistic tails
Strong coupling density matrix particles lattice
2014/12/20
The common perception is that strong coupling to the environment will always render the evolution of the system density matrix quasiclassical (in fact, diffusive) in the long time limit. We present he...
Evolution of additional (hidden) quantum variables in the interference of Bose-Einstein condensates
Additional variable hidden variables quantum mechanics the high concentration condensate
2014/12/20
Additional variables (also often called “hidden variables”) are sometimes added to standard quantum mechanics in order to remove its indeterminism or “incompleteness” and to make the measurement proce...

Quantum system condensate quantum measurement quantum mechanics
2014/12/20
Quantum systems in Fock states do not have a phase. When two or more Bose-Einstein condensates are sent into interferometers, they nevertheless acquire a relative phase under the effect of quantum mea...

Quantum measurement quantum system condensate particle measurement and quantum mechanics
2014/12/19
Quantum systems in Fock states do not have a phase. When two or more Bose-Einstein condensates are sent into interferometers, they nevertheless acquire a relative phase under the effect of quantum mea...
Quantum-limited mass flow of liquid He-3
Quantum fluid nano channel quantized conductance sensitive to temperature scattering matrix simulation
2014/12/19
We consider theoretically the possibility of observing unusual quantum fluid behavior in liquid 3He and solutions of 3He in 4He systems confined to nanochannels. In the case of pure ballistic flow at ...
Expansion of a Quantum Gas Released from an Optical Lattice
Ultracold atoms optical lattice quantum gas the diffraction optics
2014/12/19
We analyze the interference pattern produced by ultracold atoms released from an optical lattice, commonly interpreted as the momentum distributions of the trapped quantum gas. We show that for finite...
Interferometry with independent Bose-Einstein condensates: parity as an EPR/Bell quantum variable
Condensate quantum mechanical interferometer binary particles
2014/12/19
When independent Bose-Einstein condensates (BEC), described quantum mechanically by Fock (number) states, are sent into interferometers, the measurement of the output port at which the particles are d...
Worm Algorithm for Problems of Quantum and Classical Statistics
Quantum phase transition worms algorithm and strength
2014/12/19
This is a chapter of the multi-author book “Understanding Quantum Phase Transitions,” edited by Lincoln Carr and published by Taylor & Francis. In this chapter, we give a general introduction to the w...
Classical phases and quantum angles in the description of interfering Bose-Einstein condensates
Condensate random variables measurements
2014/12/19
The interference of two Bose-Einstein condensates, initially in Fock states, can be described in terms of their relative phase, treated as a random unknown variable. This phase can be understood eithe...
Quantum Corrections to the Gravitational Interaction of Massless Particles
Collinear Divergence Effective Field Theory General Relativity Infrared Divergence Massless Quantum Gravity
2014/11/20
Donoghue's effective field theory of quantum gravity is extended to include the interaction of massless particles. The collinear divergences which accompany massless particles are examined first in th...

The Existence of Quantum Entanglement Catalysts.
Entanglement catalysts entanglement states entanglement
2012/11/29
Without additional resources, it is often impossible to transform one entangled quantum state into another with local quantum operations and classical communication. Jonathan and Plenio (Phys. Rev. Le...
On a Recent Construction of "Vacuum-like" Quantum Field States in Curved Spacetime

2012/6/29
Afshordi, Aslanbeigi and Sorkin have recently proposed a construction of a distinguished "S-J state" for scalar field theory in (bounded regions of) general curved spacetimes. We establish rigorously ...
