Asymptotic Structure of Higher Dimensional Yang-Mills Theory
Temple He, Prahar Mitra
Using the covariant phase space formalism, we construct the phase space for non-Abelian gauge theories in -dimensional Minkowski spacetime for any , including the…
Phase Space Renormalization and Finite BMS Charges in Six Dimensions
Federico Capone, Prahar Mitra, Aaron Poole +1
We perform a complete and systematic analysis of the solution space of six-dimensional Einstein gravity. We show that a particular subclass of solutions -- those that are analytic…
New phases of SYM at finite chemical potential
Oscar J. C. Dias, Prahar Mitra, Jorge E. Santos
We do a systematic search of supergravity solutions that, via the AdS/CFT correspondence, are dual to thermal states in SYM at finite chemical potential. Th…
Shadows and Soft Exchange in Celestial CFT
Daniel Kapec, Prahar Mitra
We study exponentiated soft exchange in dimensional gauge and gravitational theories using the celestial CFT formalism. These models exhibit spontaneously broken asymptotic s…
Covariant Phase Space and Soft Factorization in Non-Abelian Gauge Theories
Temple He, Prahar Mitra
We perform a careful study of the infrared sector of massless non-abelian gauge theories in four-dimensional Minkowski spacetime using the covariant phase space formalism, taking i…
New Magnetic Symmetries in -Dimensional QED
Temple He, Prahar Mitra
Previous analyses of asymptotic symmetries in QED have shown that the subleading soft photon theorem implies a Ward identity corresponding to a charge generating divergent large ga…
Asymptotic Symmetries in -Dimensional Gauge Theories
Temple He, Prahar Mitra
We show that the subleading soft photon theorem in a -dimensional massless abelian gauge theory gives rise to a Ward identity corresponding to divergent large gauge transfor…
Asymptotic Symmetries and Weinberg's Soft Photon Theorem in Mink
Temple He, Prahar Mitra
We show that Weinberg's leading soft photon theorem in massless abelian gauge theories implies the existence of an infinite-dimensional large gauge symmetry which acts non-triviall…
A -Dimensional Stress Tensor for Mink Gravity
Daniel Kapec, Prahar Mitra
We consider the tree-level scattering of massless particles in -dimensional asymptotically flat spacetimes. The -matrix elements are recast as correlation funct…
Asymptotic Symmetries and Subleading Soft Photon Theorem in Effective Field Theories
Alok Laddha, Prahar Mitra
In [1,2] it was shown that the subleading soft photon theorem in tree level amplitudes in massless QED is equivalent to a new class of symmetries of the theory parameterized by a v…
Axion field induces exact symmetry
P. Mitra
While no regularization is consistent with the anomalous chiral symmetry which occurs for massless fermions, the artificial axion-induced symmetry for massive fermions is shown her…
A 2D Stress Tensor for 4D Gravity
Daniel Kapec, Prahar Mitra, Ana-Maria Raclariu +1
We use the subleading soft-graviton theorem to construct an operator whose insertion in the four-dimensional tree-level quantum gravity -matrix obeys the Vira…
Infinite-Dimensional Fermionic Symmetry in Supersymmetric Gauge Theories
Thomas T. Dumitrescu, Temple He, Prahar Mitra +1
We establish the existence of an infinite-dimensional fermionic symmetry in four-dimensional supersymmetric gauge theories by analyzing semiclassical photino dynamics in abelian ${…
2D Kac-Moody Symmetry of 4D Yang-Mills Theory
Temple He, Prahar Mitra, Andrew Strominger
Scattering amplitudes of any four-dimensional theory with nonabelian gauge group may be recast as two-dimensional correlation functions on the asymptotic two-sphere at…
New Symmetries of Massless QED
Temple He, Prahar Mitra, Achilleas P. Porfyriadis +1
An infinite number of physically nontrivial symmetries are found for abelian gauge theories with massless charged particles. They are generated by large gauge transformation…
BMS supertranslations and Weinberg's soft graviton theorem
Temple He, Vyacheslav Lysov, Prahar Mitra +1
Recently it was conjectured that a certain infinite-dimensional "diagonal" subgroup of BMS supertranslations acting on past and future null infinity ( and ${\mathsc…
Hairy black holes and solitons in global AdS 5
Oscar J. C. Dias, Pau Figueras, Shiraz Minwalla +3
We use a mix of analytic and numerical methods to exhaustively study a class of asymptotically global AdS solitons and hairy black hole solutions in negative cosmological constant…
Zeta function regularization, anomaly and complex mass term
P. Mitra
If the zeta function regularization is used and a complex mass term considered for fermions, the phase does not appear in the fermion determinant. This is not a drawback of the reg…
Time-reversal and parity conservation for gravitating quarks
P. Mitra
The complex mass term of a quark does not violate time-reversal or parity in gravitational interactions, in spite of an axial anomaly.
Complex fermion mass term, regularization and CP violation
P. Mitra
It is well known that the CP violating theta term of QCD can be converted to a phase in the quark mass term. However, a theory with a complex mass term for quarks can be regularize…
Black hole state counting in loop quantum gravity
P. Mitra
Counting of microscopic states of black holes is discussed within the framework of loop quantum gravity. There are two different ways, one allowing for all spin states and the othe…
Patching up the monopole potential
Ashok Chatterjee, P. Mitra
It is well known that a vector potential cannot be defined over the whole surface of a sphere around a magnetic monopole. A recent claim to the contrary is shown to have problems.…
Chiral phase in fermionic measure and the resolution of the strong CP problem
P. Mitra
The fermionic measure in the functional integral of a gauge theory suffers from an ambiguity in the form of a chiral phase. By fixing it, one is led once again to the conclusion th…
Statistical Entropy of Schwarzschild Black Strings and Black Holes
Saurya Das, Amit Ghosh, P. Mitra
The statistical entropy of a Schwarzschild black string in five dimensions is obtained by counting the black string states which form a representation of the near-horizon conformal…
