Spontaneous Time Asymmetry due to Horizon
Ramesh Anishetty, R. Parthasarathy
We show that quantized matter fields in the presence of background metrics with Horizon exhibit spontaneous time asymmetry. All quantized matter fields have to vanish at the horizo…
The Fermion Doubling Problem and Noncommutative Geometry
A. P. Balachandran, T. R. Govindarajan, B. Ydri
We propose a resolution for the fermion doubling problem in discrete field theories based on the fuzzy sphere and its Cartesian products.
Supergravity with Self-dual B fields and Instantons in Noncommutative Gauge Theory
S. R. Das, S. Kalyana Rama, S. P. Trivedi
We study Type IIB supergravity in the presence of (euclidean) D3 branes and nonzero self-dual B-fields. We point out that the Einstein frame metric is identical to the full geometr…
Asymptotically Free Non-Abelian Gauge Theories With Fermions and Scalars As Alternatives to QCD
N. D. Hari Dass, V. Soni
In this paper we construct non-Abelian gauge theories with fermions and scalars that nevertheless possess asymptotic freedom.The scalars are taken to be in a chiral multiplet trans…
Worldsheet approaches to D-branes on supersymmetric cycles
Suresh Govindarajan, T. Jayaraman, Tapobrata Sarkar
We consider D-branes wrapped around supersymmetric cycles of Calabi-Yau manifolds from the viewpoint of N=2 Landau-Ginzburg models with boundary as well as by consideration of boun…
Black Hole Emission Rates and the AdS/CFT Correspondence
Saurya Das, Arundhati Dasgupta
We study the emission rates of scalar, spinor and vector particles from a 5 dimensional black hole for arbitrary partial waves. The solution is lifted to 6 dimensions, and the near…
Regularisation of Chiral Gauge Theories
N. D. Hari Dass
This article gives a review of the topic of regularising chiral gauge theories and is aimed at a general audience. It begins by clarifying the meaning of chirality and goes on to d…
The Character of the Exceptional Series of Representations of SU(1,1)
Debabrata Basu, Subrata Bal, K. V. Shajesh
The character of the exceptional series of representations of SU(1,1) is determined by using Bargmann's realization of the representation in the Hilbert space of functions de…
On the Role of Chaos in the AdS/CFT Connection
S. Kalyana Rama, B. Sathiapalan
The question of how infalling matter in a pure state forms a Schwarzschild black hole that appears to be at non-zero temperature is discussed in the context of the AdS/CFT connecti…
Holographic Principle in the Closed Universe : a Resolution with Negative Pressure Matter
S. Kalyana Rama
A closed universe containing pressureless dust, more generally perfect fluid matter with pressure-to-density ratio w in the range (1/3, - 1/3), violates holographic principle appli…
High Temperature Limit of the N= 2 Matrix Model
Subrata Bal, B. Sathiapalan
The high temperature limit of a system of two D-0 branes is investigated. The partition function can be expressed as a power series in (inverse temperature). The leading term i…
