Representasi Tokoh Lisa dalam Novel Bunda Lisa Karya Jombang Santani Khairen: Kajian Psikologi Wanita (Delegation Of Lisa In Novel Bunda Lisa Written By Jombang Santani Khairen: Examined By Woman Psychology)
This article tells about the delegation of a woman in family and society. The delegation of a woman is interesting to be study because a women has a big role in family life also in society. Woman also needs to receive the prize of woman right, woman emancipation, and woman construction dealing with woman psychology. The novel entitled Bunda Lisa, written by Jombang Santani Khairen mention many aspects of woman psychology as a wife, as a mother and a teacher, as well as a housewife. That problem can be known through the structural theory includes theme, cast, character, conflict and background. The result analysis of structural theory and woman psychology examination in novel Bunda Lisa draws that the novel is appropriate along the theory used, those are structural theory and woman psychology examination
Finite Size Effects for the Ising Model Coupled to 2-D Random Surfaces
Finite size effects for the Ising Model coupled to two dimensional random
surfaces are studied by exploiting the exact results from the 2-matrix models.
The fixed area partition function is numerically calculated with arbitrary
precision by developing an efficient algorithm for recursively solving the
quintic equations so encountered. An analytic method for studying finite size
effects is developed based on the behaviour of the free energy near its
singular points. The generic form of finite size corrections so obtained are
seen to be quite different from the phenomenological parameterisations used in
the literature. The method of singularities is also applied to study the
magnetic susceptibility. A brief discussion is presented on the implications of
these results to the problem of a reliable determination of string
susceptibility from numerical simulations.Comment: 18 pages, 3 figure
Composite fermion wave functions as conformal field theory correlators
It is known that a subset of fractional quantum Hall wave functions has been
expressed as conformal field theory (CFT) correlators, notably the Laughlin
wave function at filling factor ( odd) and its quasiholes, and the
Pfaffian wave function at and its quasiholes. We develop a general
scheme for constructing composite-fermion (CF) wave functions from conformal
field theory. Quasiparticles at are created by inserting anyonic
vertex operators, , that replace a subset of the electron
operators in the correlator. The one-quasiparticle wave function is identical
to the corresponding CF wave function, and the two-quasiparticle wave function
has correct fractional charge and statistics and is numerically almost
identical to the corresponding CF wave function. We further show how to exactly
represent the CF wavefunctions in the Jain series as the CFT
correlators of a new type of fermionic vertex operators, ,
constructed from free compactified bosons; these operators provide the CFT
representation of composite fermions carrying flux quanta in the CF Landau level. We also construct the corresponding quasiparticle- and
quasihole operators and argue that they have the expected fractional charge and
statistics. For filling fractions 2/5 and 3/7 we show that the chiral CFTs that
describe the bulk wave functions are identical to those given by Wen's general
classification of quantum Hall states in terms of -matrices and - and
-vectors, and we propose that to be generally true. Our results suggest a
general procedure for constructing quasiparticle wave functions for other
fractional Hall states, as well as for constructing ground states at filling
fractions not contained in the principal Jain series.Comment: 26 pages, 3 figure
Finding the Pion in the Chiral Random Matrix Vacuum
The existence of a Goldstone boson is demonstrated in chiral random matrix
theory. After determining the effective coupling and calculating the scalar and
pseudoscalar propagators, a random phase approximation summation reveals the
massless pion and massive sigma modes expected whenever chiral symmetry is
spontaneously broken.Comment: 3 pages, 1 figure, revte
D-XY Critical Behavior in Cuprate Superconductors
We outline the universal and finite temperature critical properties of the
3D-XY model, extended to anisotropic extreme type-II superconductors, as well
as the universal quantum critical properties in 2D. On this basis we review:
(i) the mounting evidence for 3D-XY behavior in optimally doped cuprate
superconductors and the 3D to 2D crossover in the underdoped regime; (ii) the
finite size limitations imposed by inhomogeneities; (iii) the experimental
evidence for a 2D-XY quantum critical point in the underdoped limit, where the
superconductor to insulator transition occurs; (iv) the emerging implications
and constraints for microscopic models.Comment: 5 pages, 6 figure
Solitons and Quasielectrons in the Quantum Hall Matrix Model
We show how to incorporate fractionally charged quasielectrons in the finite
quantum Hall matrix model.The quasielectrons emerge as combinations of BPS
solitons and quasiholes in a finite matrix version of the noncommutative
theory coupled to a noncommutative Chern-Simons gauge field. We also
discuss how to properly define the charge density in the classical matrix
model, and calculate density profiles for droplets, quasiholes and
quasielectrons.Comment: 15 pages, 9 figure
Statistical Properties of Cross-Correlation in the Korean Stock Market
We investigate the statistical properties of the correlation matrix between
individual stocks traded in the Korean stock market using the random matrix
theory (RMT) and observe how these affect the portfolio weights in the
Markowitz portfolio theory. We find that the distribution of the correlation
matrix is positively skewed and changes over time. We find that the eigenvalue
distribution of original correlation matrix deviates from the eigenvalues
predicted by the RMT, and the largest eigenvalue is 52 times larger than the
maximum value among the eigenvalues predicted by the RMT. The
coefficient, which reflect the largest eigenvalue property, is 0.8, while one
of the eigenvalues in the RMT is approximately zero. Notably, we show that the
entropy function with the portfolio risk for the original
and filtered correlation matrices are consistent with a power-law function,
, with the exponent and
those for Asian currency crisis decreases significantly
The optical spectrum of a large isolated polycyclic aromatic hydrocarbon: hexa-peri-hexabenzocoronene, C42H18
The first optical spectrum of an isolated polycyclic aromatic hydrocarbon
large enough to survive the photophysical conditions of the interstellar medium
is reported. Vibronic bands of the first electronic transition of the all
benzenoid polycyclic aromatic hydrocarbon hexa-peri-hexabenzocoronene were
observed in the 4080-4530 Angstrom range by resonant 2-color 2-photon
ionization spectroscopy. The strongest feature at 4264 Angstrom is estimated to
have an oscillator strength of f=1.4x10^-3, placing an upper limit on the
interstellar abundance of this polycyclic aromatic hydrocarbon at 4x10^12
cm^-2, accounting for a maximum of ~0.02% of interstellar carbon. This study
opens up the possibility to rigorously test neutral polycyclic aromatic
hydrocarbons as carriers of the diffuse interstellar bands in the near future.Comment: 9 pages, 1 figure. Fixed a typo on the frequency of the 'b' ban
On the stationary points of the TAP free energy
In the context of the p-spin spherical model, we introduce a method for the
computation of the number of stationary points of any nature (minima, saddles,
etc.) of the TAP free energy. In doing this we clarify the ambiguities related
to the approximations usually adopted in the standard calculations of the
number of states in mean field spin glass models.Comment: 11 pages, 1 Postscript figure, plain Te
