Cell Natural Orbitals in Quantum Materials
Harshitra Mahalingam, Nishchhal Verma, Daniel Muñoz-Segovia +1
Understanding correlated quantum matter starts with an accurate model of the single-particle states that interact at low energies: their dispersion, band geometry, orbital content…
Cell Natural Orbitals in Interacting Topological Bands
Nishchhal Verma, Harshitra Mahalingam, Daniel Muñoz-Segovia +1
Topological bands exhibit obstruction to exponentially localized and symmetric Wannier functions, challenging the standard paradigm of representing projected interactions in terms…
Dissipation and diffusion in one-dimensional solids
Harshitra Mahalingam, Ben Andrew Olsen, Aleksandr Rodin
Using a nonperturbative classical model for ionic motion through one-dimensional (1D) solids, we explore how thermal lattice vibrations affect ionic transport properties. Based on…
Atomically-precise Vacancy-assembled Quantum Antidots
Hanyan Fang, Harshitra Mahalingam, Xinzhe Li +16
Patterning antidots ("voids") into well-defined antidot lattices creates an intriguing class of artificial structures for the periodic modulation of 2D electron systems, leading to…
Minimal model of drag in one-dimensional crystals
Harshitra Mahalingam, Zhun Wai Yap, Ben A. Olsen +1
Using a non-perturbative classical approach, we study the dynamics of a mobile particle interacting with an infinite one-dimensional (1D) chain of harmonic oscillators. This minima…
Numerical package for QFT calculations of defect-induced phenomena in graphene
Hillol Biswas, Harshitra Mahalingam, Aleksandr Rodin
We introduce a computationally efficient method based on the path integral formalism to describe defect-modified graphene. By taking into account the entire Brillouin zone, our app…
Electronic Self-passivation of Single Vacancy in Black Phosphorus via a Controlled Ionization
Hanyan Fang, Aurelio Gallardo, Dikshant Dulal +11
We report that mono-elemental black phosphorus presents a new electronic self-passivation scheme of single vacancy (SV). By means of low-temperature scanning tunneling microscopy a…
