GromovWitten classes, quantum cohomology, and enumerative geometry
 Commun. Math. Phys
, 1994
"... The paper is devoted to the mathematical aspects of topological quantum field theory and its applications to enumerative problems of algebraic geometry. In particular, it contains an axiomatic treatment of Gromov–Witten classes, and a discussion of their properties for Fano varieties. Cohomological ..."

Field Theories are defined, and it is proved that tree level theories are determined by their correlation functions. Application to counting rational curves on del Pezzo surfaces and projective spaces are given. Let V be a projective algebraic manifold. Methods of quantum field theory recently led to a

 in fourdimensions,” Nucl. Phys. B533
, 1998
"... We review the generalization of field theory to spacetime with noncommuting coordinates, starting with the basics and covering most of the active directions of research. Such theories are now known to emerge from limits of M theory and string theory, and to describe quantum Hall states. In the last ..."

. In the last few years they have been studied intensively, and many qualitatively new phenomena have been discovered, both on the classical and quantum level. Submitted to Reviews of Modern Physics.
Quantum Level Statistics of Gaussian Ensembles in
"... Onedimensional (1D) timeindependent system with a particle ， e.g. an electron ， isstudied. The system has one degree of freedom and one constant of motion ， the Hamiltonian: H=const. It means th 剖 thelD system is integrable [1]. On the other hand it was argued more than a decade ago [2] that a num ..."

put the dimensionless unit: m = 1 = O. In this work we numerically construct the lD potential whose level statistics becomes indistinguishable from that ofthe GOEtype systems. The iterative numerical method which was used in Ref.[3] is applied. It is based on the standard gradient method
Local conformal symmetry and its fate at quantum level
 5th International Conference on Math. Methods in Physics (IC 2006), Rio de Janeiro, Brazil, 2006, PoSJHEP 03
"... Abstract. The purpose of this article is to present a short review of local conformal symmetry in curved 4d spacetime. Furthermore we discuss the conformal anomaly and anomalyinduced effective actions. Despite the conformal symmetry is always broken at quantum level, it may be a basis of useful an ..."

t → W + b AND t → H + b AT THE QUANTUM LEVEL IN THE MSSM
, 1998
"... We compare the standard top quark decay and the charged Higgs decay of the top quark, t → W + b and t → H + b, at the quantum level in the MSSM. While the SUSY loop corrections to the standard top quark decay are only of a few percent, it turns out that t → H + b is a most promising candidate for ca ..."

Observation of BoseEinstein condensation in a dilute atomic vapor
 Science
, 1995
"... A BoseEinstein condensate was produced in a vapor of rubidium87 atoms that was confined by magnetic fields and evaporatively cooled. The condensate fraction first appeared near a temperature of 170 nanokelvin and a number density of 2.5 x 1012 per cubic centimeter and could be preserved for more t ..."

Insitu Laser Microprocessing at the Quantum Level

"... One of the biggest challenges of nanotechnology is the fabrication of nanoobjects with perfectly controlled properties. Here we employ a focused laser beam both to characterize and to insitu modify single semiconductor structures by heating them from cryogenic to high temperatures. The heat treatm ..."

treatment allows us to blueshift, in a broad range and with resolutionlimited accuracy, the quantized energy levels of light and charge carriers confined in optical microcavities and selfassembled quantum dots (QDs). We demonstrate the approach by tuning an optical mode into resonance with the emission
Bethe Ansatz for Quantum Strings

We propose Bethe equations for the diagonalization of the Hamiltonian of quantum strings on AdS5×S 5 at large string tension and restricted to certain large charge states from a closed su(2) subsector. The ansatz differs from the recently proposed allloop gauge theory asymptotic Bethe ansatz by add ..."
