Galilean Yang-Mills Theory
Arjun Bagchi, Rudranil Basu, Ashish Kakkar +1
We investigate the symmetry structure of the non-relativistic limit of Yang-Mills theories. Generalising previous results in the Galilean limit of electrodynamics, we discover that…
A Schrödinger approach to Newton-Cartan and Hořava-Lifshitz gravities
Hamid R. Afshar, Eric A. Bergshoeff, Aditya Mehra +2
We define a `non-relativistic conformal method', based on a Schrödinger algebra with critical exponent z = 2, as the non-relativistic version of the relativistic conformal method.…
Free-field realisations of the BMS algebra and its extensions
Nabamita Banerjee, Dileep P. Jatkar, Sunil Mukhi +1
We construct an explicit realisation of the BMS algebra with nonzero central charges using holomorphic free fields. This can be extended by the addition of chiral matter to a r…
Thermalization in 2D critical quench and UV/IR mixing
Gautam Mandal, Shruti Paranjape, Nilakash Sorokhaibam
We consider quantum quenches in models of free scalars and fermions with a generic time-dependent mass that goes from to zero. We prove that, as anticipated in MSS \ci…
On 2d Conformal Field Theories with Two Characters
Harsha R. Hampapura, Sunil Mukhi
Rational CFT's are classified by an integer , the number of zeroes of the Wronskian of their characters in moduli space. For they satisfy non-singular modular-invari…
Null Fluids - A New Viewpoint of Galilean Fluids
Nabamita Banerjee, Suvankar Dutta, Akash Jain
This article is a detailed version of our short letter `On equilibrium partition function for non-relativistic fluid' [arXiv:1505.05677] extended to include an anomalous sym…
Dynamics of Perturbations in Double Field Theory & Non-Relativistic String Theory
Sung Moon Ko, Charles Melby-Thompson, Rene Meyer +1
Double Field Theory provides a geometric framework capable of describing string theory backgrounds that cannot be understood purely in terms of Riemannian geometry -- not only glob…
Higher Spin de Sitter Quantum Gravity
Rudranil Basu
We consider Einstein gravity with positive cosmological constant coupled with higher spin interactions and calculate Euclidean path integral perturbatively. We confine ourselves to…
Tensionless Strings from Worldsheet Symmetries
Arjun Bagchi, Shankhadeep Chakrabortty, Pulastya Parekh
We revisit the construction of the tensionless limit of closed bosonic string theory in the covariant formulation in the light of Galilean conformal symmetry that rises as the resi…
Yang-Mills theories and quadratic forms
Sudarshan Ananth, Lars Brink, Mahendra Mali
We show that the Hamiltonian of (N=1;d=10) super Yang-Mills can be expressed as a quadratic form in a very similar manner to that of the (N=4;d=4) theory. We find a similar quadrat…
Equilibrium partition function for nonrelativistic fluids
Nabamita Banerjee, Suvankar Dutta, Akash Jain
We construct an equilibrium partition function for a non-relativistic fluid and use it to constrain the dynamics of the system. The construction is based on light cone reduction, w…
Light-cone gravity in dS
Sudarshan Ananth, Mahendra Mali
We derive a closed form expression for the light-cone Lagrangian describing pure gravity on a four-dimensional de Sitter background. We provide a perturbative expansion, of this La…
Fermi-Bose cubic couplings in light-cone field theories
Y. S. Akshay, Sudarshan Ananth
We derive light-cone cubic interaction vertices involving fermions and bosons of arbitrary spin by demanding closure of the Poincaré algebra. We derive the three-point scattering a…
A membrane paradigm at large D
Sayantani Bhattacharyya, Anandita De, Shiraz Minwalla +2
We study invariant solutions of the classical vacuum Einstein equations in dimensions. In the limit with held fixed we construct a class of sol…
Modular invariance and entanglement entropy
Sagar Fakirchand Lokhande, Sunil Mukhi
We study the Renyi and entanglement entropies for free 2d CFT's at finite temperature and finite size, with emphasis on their properties under modular transformations of the torus.…
Higher Derivative Corrections to Charged Fluids in 2n Dimensions
Nabamita Banerjee, Suvankar Dutta, Akash Jain
We study anomalous charged fluid in -dimensions () up to sub-leading derivative order. Only the effect of gauge anomaly is important at this order. Using the Euclidean…
