Analytic solutions for Dp branes in SFT
This is the follow-up of a previous paper [ArXiv:1105.5926], where we
calculated the energy of an analytic lump solution in SFT, representing a
D24-brane. Here we describe an analytic solution for a Dp-brane, for any p, and
compute its energy.Comment: 14 page
Marginal Deformations as Lower Dimensional D-brane Solutions in Open String Field theory
By direct calculation we showed that a finite analytic solution for marginal
deformation of open string field theory, by a matter primary operator with
singular OPE, can be obtained to all orders in the deformation parameter. In
particular, we obtained solutions that describe lower dimensional D-branes and
our results agree with the results obtained when the same problem is treated in
the world-sheet conformal field theory language.Comment: 19 pages, 4 figure
Abelian Gauge Invariance of the WZ-type Coupling in ABJM Theory
We construct the interaction terms between the worldvolume fields of multiple
M2-branes and 3-form gauge field of 11-dimensional supergravity, in the context
of ABJM theory. The obtained Wess-Zumino-type coupling is simultaneously
invariant under the UU non-Abelian
gauge transformation of the ABJM theory and the Abelian gauge transformation of
the 3-form field in 11-dimensional supergravity.Comment: 16 pages, minor corrections, published versio
Gravity from Entanglement and RG Flow in a Top-down Approach
The duality between a -dimensional conformal field theory with relevant
deformation and a gravity theory on an asymptotically AdS geometry, has
become a suitable tool in the investigation of the emergence of gravity from
quantum entanglement in field theory. Recently, we have tested the duality
between the mass-deformed ABJM theory and asymptotically AdS gravity
theory, which is obtained from the KK reduction of the 11-dimensional
supergravity on the LLM geometry. In this paper, we extend the KK reduction
procedure beyond the linear order and establish non-trivial KK maps between
4-dimensional fields and 11-dimensional fluctuations. We rely on this
gauge/gravity duality to calculate the entanglement entropy by using the
Ryu-Takayanagi holographic formula and the path integral method developed by
Faulkner. We show that the entanglement entropies obtained using these two
methods agree when the asymptotically AdS metric satisfies the linearized
Einstein equation with nonvanishing energy-momentum tensor for two scalar
fields. These scalar fields encode the information of the relevant deformation
of the ABJM theory. This confirms that the asymptotic limit of LLM geometry is
the emergent gravity of the quantum entanglement in the mass-deformed ABJM
theory with a small mass parameter. We also comment on the issue of the
relative entropy and the Fisher information in our setup.Comment: 42 pages, no figure, minor corrections, references adde
Exact Holography of the Mass-deformed M2-brane Theory
We test the holographic relation between the vacuum expectation values of
gauge invariant operators in mass-deformed ABJM theory and the LLM geometries with
orbifold in 11-dimensional supergravity. To do that, we apply
the Kaluza-Klein reduction to construct a 4-dimensional gravity theory and
implement the holographic renormalization procedure. We obtain an exact
holographic relation for the vacuum expectation values of the chiral primary
operator with conformal dimension , which is given by , for large and
. Here factor is independent of . Our results involve
infinite number of exact dual relations for all possible supersymmetric Higgs
vacua and so provide a nontrivial test of gauge/gravity duality away from the
conformal fixed point. We also extend our results to the case of for
LLM geometries represented by rectangular-shaped Young-diagrams.Comment: 6 pages, major corrections in section 3 and 4, references added,

Mass-deformed ABJM Theory and LLM Geometries: Exact Holography
We present a detailed account and extension of our claim in arXiv:1610.01490.
We test the gauge/gravity duality between the mass-deformed ABJM
theory with UU gauge symmetry and the 11-dimensional
supergravity on LLM geometries with SO(4)/
SO(4)/ isometry, in the large limit. Our analysis is
based on the evaluation of vacuum expectation values of chiral primary
operators from the supersymmetric vacua of mass-deformed ABJM theory and from
the implementation of Kaluza-Klein holography to the LLM geometries. We focus
on the chiral primary operator with conformal dimension . We show
that for
all supersymmetric vacuum solutions and LLM geometries with , where the
factor is independent of . We also confirm that the vacuum
expectation value of the the energy momentum tensor is vanishing as expected by
the supersymmetry. We extend our results to the case of for LLM
geometries represented by rectangular-shaped Young-diagrams. In analogy with
the Coulomb branch of the super Yang-Mills theory, we argue that
the discrete Higgs vacua of the mABJM theory as well as the corresponding LLM
geometries are parametrized by the vevs of the chiral primary operators.Comment: 44 pages, 1 figure, major corrections in section 3 and 5, references

Tanggung Jawab Dan Upaya Penyelesaian Perselisihan Antara PT Pertamina (Persero) Dengan Pihak SPBU Dalam Pelaksanaan Perjanjian Pendistribusian Bahan Bakar Minyak Di Kota Kendari
Author raised the issue about form of responsibility and dispute resolution efforts PT Pertamina with the filling stations in the implementation of Fuel Distribution Agreement, while the form of an agreement between two parties is a kind of standard contract which it created and defined by the party dominates, namely PT Pertamina, so often have problems in implementing the agreement that has been agreed upon by both parties, One is in default which resulted in one of the parties should be responsible for problems that arise. The existence of some of the contents of the agreement are not properly implemented, will impact a loss for the other party, so as to overcome this is necessary to responsibility and remedies that must be done to overcome the existing problems. The purpose of this study was to determine and analyze the form of responsibility and remedies undertaken by PT Pertamina (Persero) in the event of a default problems in implementing the distribution of fuel to the General Fuel Station in Kendari city. The research by the author using socio-juridical where researchers looked at the facts that occurred in the field and examined by reference to the letter of the law and existing agreements. Results of this study concluded that in implementing the agreement, especially regarding the implementation of rights and obligations, still found a common problem that, PT Pertamina provide some ways that can be done as a form of responsibility to resolve the existing problems. As for the remedies to be taken in the event of a dispute related to the existing problems, can be done with two options, namely, by deliberation and litigation (court), as agreed in the contents of the agreement. Thus, to solve this problem required cooperation by all parties concerned. Both the PT Pertamina, gas stations, and Local Government
