Aspects of topology of condensates and knotted solitons in condensed matter systems [PDF]

, 1992
The knotted solitons introduced by Faddeev and Niemi is presently a subject of great interest in particle and mathematical physics. In this paper we give a condensed matter interpretation of the recent results of Faddeev and Niemi.Comment: v2: Added a ...

What can gauge-gravity duality teach us about condensed matter physics? [PDF]

, 2012
I discuss the impact of gauge-gravity duality on our understanding of two classes of systems: conformal quantum matter and compressible quantum matter.

Zoo of quantum-topological phases of matter [PDF]

, 2017
What are topological phases of matter? First, they are phases of matter at zero temperature. Second, they have a non-zero energy gap for the excitations above the ground state. Third, they are disordered liquids that seem have no feature.

Early Universe Quantum Processes in BEC Collapse Experiments [PDF]

, 2005
We show that in the collapse of a Bose-Einstein condensate (BEC) {For an excellent introduction to BEC theory, see C. Pethick and H. Smith, Bose-Einstein condensation in dilute gases (Cambridge University Press, Cambridge, England, 2002)} certain ...

Cold quantum gases: coherent quantum phenomena from Bose-Einstein condensation to BCS pairing of fermions [PDF]

, 2004
Studies of trapped quantum gases of bosons and of fermions have opened up a new range of many-body problems, having a strong overlap with nuclear and neutron star physics.

The formation of vortex loops (strings) in continuous phase transitions [PDF]

, 2001
The formation of vortex loops (global cosmic strings) in an O(2) linear sigma model in three spatial dimensions is analyzed numerically. For over-damped Langevin dynamics we find that defect production is suppressed by an interaction between correlated ...

Testing cosmological defect formation in the laboratory

, 2001
Topological defects such as cosmic strings may have been formed at early-universe phase transitions. Direct tests of this idea are impossible, but the mechanism can be elucidated by studying analogous processes in low-temperature condensed-matter systems.

From Trapped Atoms to Liberated Quarks [PDF]

, 2006
We discuss some aspects of cold atomic gases in the unitarity limit that are of interest in connection with the physics of dense hadronic matter. We consider, in particular, the equation of state at zero temperature, the magnitude of the pairing gap, and

Quantum Group based Modeling for the description of high temperature superconductivity and antiferromagnetism: Some supporting evidence

, 2001
Following our recent conjecture to model the phenomenona of antiferromagnetism and superconductivity by quantum symmetry groups, we propose in the present note three toy models, namely, one based on SO_{q}(3) the other two constructed with the SO_{q}(4 ...

BEC Collapse and Dynamical Squeezing of Vacuum Fluctuations [PDF]

, 2003
We analyze the phenomena of Bose Novae, as described by Donley et al [Nature 412, 295 (2001)], by focusing on the behavior of excitations or fluctuations above the condensate, as driven by the dynamics of the condensate (rather than the dynamics of the ...
