Double Copy from the Flipped Null String
Arjun Bagchi, Sachin Grover, Sharang Rajesh Iyer +2
We study the double-copy structure of tree amplitudes of the bosonic null string in the flipped vacuum. We show that its level-one vector correlator supplies the Cachazo-He-Yuan (C…
Scattering of Null strings - Flipped Vacuum & CHY
Arjun Bagchi, Sachin Grover, Sharang Rajesh Iyer +2
We investigate the scattering of null tensionless strings. Classical null strings, given by the ILST action, give rise to three distinct quantum theories built on different vacua a…
High energy scattering and null strings
Arjun Bagchi, Sachin Grover, Sharang Rajesh Iyer +1
We propose an instrinsic worldsheet description of the ultra-high energy regime of string scattering based on worldsheet symmetries. At very high energies, the fundamental string b…
Tetrahedral rotations in alkaline-earth metal orthovanadates
Amartyajyoti Saha, Turan Birol
The alkaline-earth orthovanadate SrVO with the palmierite structure is reported to host a dielectric anomaly as well as a structural phase transition above the room tem…
and Carrollian Holography
Amartya Saha
In a D Carrollian conformal field theory, the Ward identities of the two local fields and , entirely built out of the Carrollian conformal stress-tensor, contai…
Carrollian Approach to D Flat Holography
Amartya Saha
The isomorphism between the (extended) BMS algebra and the D Carrollian conformal algebra hints towards a co-dimension one formalism of flat holography with the field theo…
Coupled Ferroelectricity and Superconductivity in Bilayer -MoTe
Apoorv Jindal, Amartyajyoti Saha, Zizhong Li +8
Achieving electrostatic control of quantum phases is at the frontier of condensed matter research. Recent investigations have revealed superconductivity tunable by electrostatic do…
Non-Lorentzian Kač-Moody Algebras
Arjun Bagchi, Ritankar Chatterjee, Rishabh Kaushik +2
We investigate two dimensional (2d) quantum field theories which exhibit Non- Lorentzian Kač-Moody (NLKM) algebras as their underlying symmetry. Our investigations encompass both 2…
Intrinsic Approach to D Carrollian Conformal Field Theory
Amartya Saha
The 3D Bondi-Metzner-Sachs (BMS) algebra that is the asymptotic symmetry algebra at null infinity of the D asymptotically flat space-time is isomorphic to the D Carro…
Revealing the competition between charge-density wave and superconductivity in CsVSb through uniaxial strain
Tiema Qian, Morten H. Christensen, Chaowei Hu +5
In this paper we report the impact of uniaxial strain applied along the crystalline axis on the newly discovered kagome superconductor CsVSb. At ambient c…
Layer Coherent Phase in Double Layer graphene at
Amartya Saha, Ankur Das
In the recent advancement in graphene heterostructures, it is possible to create a double layer tunnel decoupled graphene system that has a strong interlayer electronic interaction…
First-principles characterization of the magnetic properties of Cu(OH)Br
Dominique M. Gautreau, Amartyajyoti Saha, Turan Birol
Low dimensional spin-1/2 transition metal oxides and oxyhalides continue to be at the forefront of research investigating nonclassical phases such as quantum spin liquids. In this…
Emergence of spin-active channels at a quantum Hall interface
Amartya Saha, Suman Jyoti De, Sumathi Rao +2
We study the ground state of a system with an interface between and in the quantum Hall regime. Far from the interface, for a range of interaction strengths, the …
BMS Modular Diaries: Torus one-point function
Arjun Bagchi, Poulami Nandi, Amartya Saha +1
Two dimensional field theories invariant under the Bondi-Metzner-Sachs (BMS) group are conjectured to be dual to asymptotically flat spacetimes in three dimensions. In this paper,…
BMS Characters and Modular Invariance
Arjun Bagchi, Amartya Saha, Zodinmawia
We construct the characters for the highest weight representations of the 3d Bondi-Metzner-Sachs (BMS) algebra. We then use these to construct the partition function and show h…
