Signature change as phase transition in holography
Marcelo Botta Cantcheff
In holographic quantum gravity, Euclidean pieces of the spacetime appear in the large N limit as representing semi-classical states of the theory. In this essay, we argue that the…
Spacetime topology from holographic entanglement
Marcelo Botta Cantcheff
An asymptotically AdS geometry connecting two or more boundaries is given by a entangled state, that can be expanded in the product basis of the Hilbert spaces of each CFT living o…
Entanglement from Dissipation and Holographic Interpretation
M. Botta Cantcheff, Alexandre L. Gadelha, Dáfni F. Z. Marchioro +1
In this work we study a dissipative field theory where the dissipation process is manifestly related to dynamical entanglement and put it in the holographic context. Such endeavour…
TFD Extension of Open String Field Theory
M. Botta Cantcheff, R. J. Scherer Santos
We study the application of the rules of Thermo Field Dynamics (TFD) to the covariant formulation of Open String Field Theory (OSFT). We extend the states space and fields accordin…
Area Operators in Holographic Quantum Gravity
Marcelo Botta Cantcheff
We argue that the holographic formula relating entanglement entropy and the area of a minimal surface is the key to define the area of surfaces in the (emergent) spacetime from the…
String in AdS Black Hole: A Thermo Field Dynamic Approach
M. Botta Cantcheff, Alexandre L. Gadelha, Dafni F. Z. Marchioro +1
Based on Maldacena's description of an eternal AdS-black hole, we reassess the Thermo Field Dynamics (TFD) formalism in the context of the AdS/CFT correspondence. The model studied…
Quantum states of the spacetime, and formation of black holes in AdS
Marcelo Botta Cantcheff
We argue that a non-perturbative description of quantum gravity should involve two (non-interacting) copies of a dual field theory on the boundary, and describe the states of the s…
The Doublet Extension of Tensor Gauge Potentials and a Reassessment of the Non-Abelian Topological Mass Mechanism
M. Botta Cantcheff, J. A. Helayel-Neto
A well-defined local non-Abelian gauge connection involving a rank-p gauge B-field was introduced a decade ago. This was achieved by introducing doublet groups and doublet-assemble…
Emergent spacetime, and a model for unitary gravitational collapse in AdS
Marcelo Botta Cantcheff
We propose a CFT unitary description of the gravitational collapse. The starting point is the model of a black hole in AdS proposed by Maldacena in arXiv: 0106112 [hep-th]. We show…
Spacetime Geometry as Statistic Ensemble of Strings
Marcelo Botta Cantcheff
Jacobson theorem (Ref. \cite{jacobson}) shows that Einstein gravity may be understood as a thermodynamical equation of state; a microscopic realization of this result is however la…
String Entanglement and D-branes as Pure States
Marcelo Botta Cantcheff
We study the entanglement of closed strings degrees of freedom in order to investigate the microscopic structure and statistics of objects as D-branes. By considering the macroscop…
Wormhole solutions to Horava gravity
Marcelo Botta-Cantcheff, Nicolas Grandi, Mauricio Sturla
We present wormhole solutions to Horava non-relativistic gravity theory in vacuum. We show that, if the parameter is set to one, transversable wormholes connecting two asymptot…
Einstein-Cartan formulation of Chern-Simons Lorentz-violating Gravity
Marcelo Botta Cantcheff
We consider a modification of the standard Einstein theory in four dimensions, alternative to R. Jackiw and S.-Y. Pi, Phys. Rev. D 68, 104012 (2003), since it is based on the first…
D-branes as coherent states in the open string channel
Marcelo Botta Cantcheff
We show that bosonic D-brane states may be represented as coherent states in an open string representation. By using the Thermo-Field Dynamics (TFD) formalism, we may construct a c…
On the Microscopical Structure of the Classical Spacetime
Marcelo Botta Cantcheff
Our purpose here is to introduce the idea of viewing the spacetime as a macroscopic complex system which, consequently, cannot be directly quantized. It should be thought of as a c…
2-Form Gauge Field Theories and "No Go" for Yang-Mills Relativistic Actions
Marcelo Botta Cantcheff
The transformation properties of a Kalb-Ramond field are those of a gauge potential. However, it is not clear what is the group structure to which these transformations are associa…
Doublet Groups, Extended Lie Algebras, and Well Defined Gauge Theories for the Two Form Field
Marcelo Botta Cantcheff
We propose a symmetry law for a doublet of different form fields, which resembles gauge transformations for matter fields. This may be done for general Lie groups, resulting in an…
Duality in Noncommutative Topologically Massive Gauge Field Theory Revisited
M. Botta Cantcheff, Pablo Minces
We introduce a master action in noncommutative space, out of which we obtain the action of the noncommutative Maxwell-Chern-Simons theory. Then, we look for the corresponding dual…
On the relation between the propagators of dual theories
A. P. Baeta Scarpelli, M. Botta Cantcheff, J. A. Helayel-Neto
In this paper, we show that the propagator of the dual of a general Proca-like theory, derived from the gauging iterative Noether Dualization Method, can be written by means of a s…
Dual embedding of the Lorentz-violating electrodinamics and Batalin-Vilkovisky quantization
M. Botta Cantcheff, C. F. L. Godinho, A. P. Baêta Scarpelli +1
Modifications of the electromagnetic Maxwell Lagrangian in four dimensions have been considered by some authors. One may include an explicit massive term (Proca) and a topological…
The Kalb-Ramond field as a connection on a flat space time
M. Botta Cantcheff
We obtain a (Abelian) two form field as a connection on a flat space-time and its corresponding field strength is canonically constructed.
Duality between Noncommutative Yang-Mills-Chern-Simons and Non-Abelian Self-Dual Models
M. Botta Cantcheff, Pablo Minces
By introducing an appropriate parent action and considering a perturbative approach, we establish, up to fourth order terms in the field and for the full range of the coupling cons…
On the Group Structure of the Kalb-Ramond Gauge Symmetry
M. Botta Cantcheff
The transformation properties of a Kalb-Ramond field are those of a gauge field; however, it is not clear which is the group structure these transformations are associated with. Th…
Bosonization and Duality in Arbitrary Dimensions: New Results
M. Botta Cantcheff, J. A. Helayël-Neto
A generic massive Thirring Model in three space-time dimensions exhibits a correspondence with a topologically massive bosonized gauge action associated to a self-duality constrain…
