RG Interfaces from Double-Trace Deformations
Simone Giombi, Elizabeth Helfenberger, Himanshu Khanchandani
We study a class of interface conformal field theories obtained by taking a large CFT and turning on a relevant double-trace deformation over half space. At low energies, this…
Effective Field Theory of Conformal Boundaries
Oleksandr Diatlyk, Himanshu Khanchandani, Fedor K. Popov +1
We introduce an effective field theory (EFT) for conformal impurity by considering a pair of transversely displaced impurities and integrating out modes with mass inversely proport…
Defect Fusion and Casimir Energy in Higher Dimensions
Oleksandr Diatlyk, Himanshu Khanchandani, Fedor K. Popov +1
We study the operator algebra of extended conformal defects in more than two spacetime dimensions. Such algebra structure encodes the combined effect of multiple impurities on phys…
Line Defects in Fermionic CFTs
Simone Giombi, Elizabeth Helfenberger, Himanshu Khanchandani
We study line defects in the fermionic CFTs in the Gross-Neveu-Yukawa universality class in dimensions . These CFTs may be described as the IR fixed points of the Gross-Neve…
Long Range, Large Charge, Large
Simone Giombi, Elizabeth Helfenberger, Himanshu Khanchandani
We study operators with large charge in the -dimensional model with long range interactions that decrease with the distance as , where is a continuous…
Fermions in AdS and Gross-Neveu BCFT
Simone Giombi, Elizabeth Helfenberger, Himanshu Khanchandani
We study the boundary critical behavior of conformal field theories of interacting fermions in the Gross-Neveu universality class. By a Weyl transformation, the problem can be stud…
Monodromy Defects from Hyperbolic Space
Simone Giombi, Elizabeth Helfenberger, Ziming Ji +1
We study monodromy defects in symmetric scalar field theories in dimensions. After a Weyl transformation, a monodromy defect may be described by placing the theory on $S…
Aspects of CFTs on Real Projective Space
Simone Giombi, Himanshu Khanchandani, Xinan Zhou
We present an analytic study of conformal field theories on the real projective space , focusing on the two-point functions of scalar operators. Due to the partially…
CFT in AdS and boundary RG flows
Simone Giombi, Himanshu Khanchandani
Using the fact that flat space with a boundary is related by a Weyl transformation to anti-de Sitter (AdS) space, one may study observables in boundary conformal field theory (BCFT…
Models with Boundary Interactions and their Long Range Generalizations
Simone Giombi, Himanshu Khanchandani
We study the critical properties of scalar field theories in dimensions with invariant interactions localized on a -dimensional boundary. By a combination of large…
Constraining parameters of effective field theory of inflation from Planck data
Anindya Banerjee, Himanshu Khanchandani
The Cosmic Microwave Background can provide information regarding physics of the very early universe, more specifically, of the matter-radiation distribution of the inflationary er…
Velocity-induced Heavy Quarkonium Dissociation using the gauge-gravity correspondence
Binoy Krishna Patra, Himanshu Khanchandani, Lata Thakur
Using the gauge-gravity duality we have obtained the potential between a heavy quark and an antiquark pair, which is moving perpendicular to the direction of orientation, in a stro…
Heavy Quark Potential at Finite Temperature in a Dual Gravity Closer to Large N QCD
Binoy Krishna Patra, Himanshu Khanchandani
In gauge-gravity duality, the heavy quark potential at finite temperature is usually calculated with the pure AdS background, which does not capture the renormalization group (RG)…
