Modular covariance and uniqueness of deformed CFTs
Ofer Aharony, Shouvik Datta, Amit Giveon +2
We study families of two dimensional quantum field theories, labeled by a dimensionful parameter , that contain a holomorphic conserved current . We assume that the…
Modular invariance and uniqueness of deformed CFT
Ofer Aharony, Shouvik Datta, Amit Giveon +2
Any two dimensional quantum field theory that can be consistently defined on a torus is invariant under modular transformations. In this paper we study families of quantum field th…
Nature of magnetism and transport in BxCyNz thin films: The intriguing role of nitrogen defects in the electronic structure
Rajesh Mandal, Rohit Babar, Malvika Tripathi +4
Boron carbonitride (BxCyNz) represents an interesting family of materials containing all light elements and two dimensional graphene like hybrid layers. Although rich literature ex…
deformed partition functions
Shouvik Datta, Yunfeng Jiang
We demonstrate the presence of modular properties in partition functions of deformed conformal field theories. These properties are verified explicitly for the deformed…
Probing thermality beyond the diagonal
Enrico M. Brehm, Diptarka Das, Shouvik Datta
We investigate the off-diagonal sector of eigenstate thermalization using both local and non-local probes in 2-dimensional conformal field theories. A novel analysis of the asympto…
Experimental evidences of trions and Fermi edge singularity in single barrier GaAs/AlAs/GaAs heterostructure using photocapacitance spectroscopy
Amit Bhunia, Mohit Kumar Singh, Y. Galvao Gobato +2
In this paper, we show how photocapacitance spectra can probe two dimensional excitonic complexes and Fermi edge singularity as a function of applied bias around 100 K. In lower de…
