Zagier's weight mock modular form
Ajit Bhand, Ranveer Kumar Singh
Mock modular forms have their origins in Ramanujan's pioneering work on mock theta functions. In a 1975 paper, Zagier proved certain transformation properties of the generating fun…
Isomorphism of Skew-Holomorphic Harmonic Maass-Jacobi Forms and Certain Weak Harmonic Maass Forms
Ranveer Kumar Singh
Recently Bringmann, Raum and Richter generalised the definition of Jacobi forms and Skoruppa's skew-holomorphic Jacobi forms by intertwining with harmonic Maass forms. We prove the…
Controlled creation and annihilation of stringless robust emergent magnetic monopoles in artificial spin ice
N. Keswani, R. Lopes, Y. Nakajima +6
Magnetic analogue of an isolated free electric charge, i.e., a magnet with a single north or south pole, is a long sought-after particle which remains elusive so far. In magnetical…
Maass lifts of half-integral weight Eisenstein series and theta powers
Ajit Bhand, Karam Deo Shankhadhar, Ranveer Kumar Singh
In this paper, we explicitly construct mock modular forms whose shadows are Eisenstein series of arbitrary integral and half-integral weight, level and character at the cusps $\inf…
Bhargava's Cube and Black Hole Charges
Nabamita Banerjee, Ajit Bhand, Suvankar Dutta +2
Black holes in a class of string compactifications, known as STU models, carry four electric and four magnetic charges. Furthermore a duality group, given by the product of three c…
Accessing low-energy magnetic microstates in symmetry-broken isolated square artificial spin ice vertices with magnetic field
Neeti Keswani, Ranveer Singh, Yoshikata Nakajima +3
In artificial spin ice systems, an interplay of defects and dipolar interactions is expected to play important roles in stabilizing different collective magnetic states. In this wo…
Investigating the role of Cu foil orientation in the growth of large BN films synthesized by reactive RF magnetron sputtering
Nilanjan Basu, Alapan Dutta, Ranveer Singh +2
Two dimensional materials are an emerging class of materials which is transforming the present day research activity on a phenomenal scale. Hexagonal boron nitride is a wide band g…
