Field Theory of Quantum Hall Effects, Composite
, 1998
"... A field theory of quantum Hall effects is constructed based on the compositeboson picture. It is tightly related with the microscopic wavefunction theory. The characteristic feature is that the field operator describes solely the physical degrees of freedom representing the deviation from the Laug ..."

merely as a lowenergy excitation within the lowest Landau level and not as a solution of the effective nonlinear sigma model. We use it as a consistency check of the Skyrmion theory that the Skyrmion is reduced to the vortex in the vanishing limit of the Skyrmion size. We evaluate the activation energy
Spontaneous Interlayer Coherence in DoubleLayer Quantum Hall Systems: Symmetry Breaking Interactions, InPlane Fields and Phase Solitons
, 2008
"... At strong magnetic fields doublelayer twodimensionalelectrongas systems can form an unusual broken symmetry state with spontaneous interlayer phase coherence. The system can be mapped to an equivalent system of pseudospin 1/2 particles with pseudospindependent interactions and easyplane magnet ..."

The Physics of Vortex Matter
"... Several examples of the recent progress in comprehension of the equilibrium properties of vortex matter will be presented. Using microscopic Hall sensors and vortex shaking by inplane ac field, a thermodynamic evidence of a firstorder disorderdriven transition at intermediate temperatures in BSCC ..."

optical imaging we find that the thermallydriven melting transition is significantly broadened globally by material disorder, yet locally it remains a sharp firstorder transition. Magnetic decoration studies show that a low concentration of columnar defects destroys the longrange order of the solid, forming
QUANTIZED VORTICES IN ATOMIC BOSEEINSTEN CONDENSATES
, 709
"... In this review, we give an overview of the experimental and theoretical advances in the physics of quantized vortices in dilute atomicgas Bose–Einstein condensates in a trapping potential, especially focusing on experimental research activities and their theoretical interpretations. Making good use ..."

Boulevard of Broken Symmetries
"... Effective theories of quantum liquids (superconductors and superfluids of various types) are derived starting from microscopic models at the absolute zero of temperature. Special care is taken to assure Galilei invariance. The effective theories are employed to investigate the quantum numbers carrie ..."

The classical, finitetemperature phase transitions to the normal state are discussed from the point of view of dual theories, where the defects

Exclusonic quasiparticles and thermodynamics of fractional quantum Hall liquids
 Phys. Rev. B57
, 1998
"... Quasielectrons and quasiholes in the fractional quantum Hall liquids obey fractional (including nontrivial mutual) exclusion statistics. Their statistics matrix can be determined from several possible statecounting scheme, involving different assumptions on statistical correlations. Thermal activat ..."

"... Motility of cells is at the root of many fundamental processes in biology: from sperm cells swimming to fertilize an egg cell, to metastatic tumor cells crawling to invade nearby tissues. We will discuss the mechanical bases of cellular motility by swimming and crawling. Special emphasis will be pla ..."

Language English Article dissertation (summary + original articles) In 1995, atomic physics took a quantum leap with the experimental discovery of almost ideal Bose–Einstein condensation in dilute gases of alkali atoms. The gaseous condensates offer a rare chance to study an interacting manyparticl ..."
