Symmetries in zero and finite center-of-mass momenta excitons
Robin Bajaj, Namana Venkatareddy, H. R. Krishnamurthy +1
We present a symmetry-based framework for the analysis of excitonic states, incorporating both time-reversal and space-group symmetries. We demonstrate the use of time-reversal and…
Enhanced Phonon-Assisted Tunneling in Metal -- Twisted Bilayer Graphene Junctions
Radhika Soni, Suvronil Datta, Robin Bajaj +7
We report planar tunneling spectroscopy measurements on metal-WSe-twisted bilayer graphene heterostructures across a broad range of gate and bias voltages. The observed experim…
Probing Phonon Modes in Reconstructed twisted Homo and Hetero Bilayer System
Sushil Kumar Sahu, Robin Bajaj, Syed Ummair Ali +7
Twist angle engineering in van der Waals homo and hetero-bilayers introduces profound modifications in their electronic, optical and mechanical properties due to lattice reconstruc…
Calculation of Gilbert damping and magnetic moment of inertia using torque-torque correlation model within ab initio Wannier framework
Robin Bajaj, Seung-Cheol Lee, H. R. Krishnamurthy +2
Magnetization dynamics in magnetic materials are well described by the modified semiclassical Landau-Lifshitz-Gilbert (LLG) equation, which includes the magnetic damping and th…
Controlling Umklapp scattering in bilayer graphene moir'e superlattice
Mohit Kumar Jat, Shubhankar Mishra, Harsimran Kaur Mann +6
In this Letter, we present experimental findings on electron-electron scattering in a two-dimensional moir'e heterostructure with tunable Fermi wave vector, reciprocal lattice vect…
Higher-order Bragg gaps in the electronic band structure of bilayer graphene renormalized by recursive supermoiré potential
Mohit Kumar Jat, Priya Tiwari, Robin Bajaj +7
This letter presents our findings on the recursive band gap engineering of chiral fermions in bilayer graphene doubly aligned with hBN. By utilizing two interfering moiré potential…
Atomic relaxation and flat bands in strain-engineered transition metal dichalcogenide bilayer moiré systems
Sudipta Kundu, Indrajit Maity, Robin Bajaj +2
Strain-induced lattice mismatch leads to moiré patterns in homobilayer transition metal dichalcogenides (TMDs). We investigate the structural and electronic properties of such stra…
