Spectroscopic evidence of disorder-induced quantum phase transitions in monolayer Fe(Te,Se) superconductor
Guanyang He, Ziqiao Wang, Longxin Pan +5
The superconductor-insulator transition as a paradigm of quantum phase transitions has attracted tremendous interest over the past three decades. While the magnetic field and carri…
Local Hall Conductivity in Disordered Topological Insulators
Zachariah Addison, Nandini Trivedi
We derive the expression for the local Hall conductivity for systems that lack translation symmetry and use it to study the local fluctuations of the Hall signal around disordered…
Enhancement of Curie Temperature in Ferromagnetic Insulator-Topological Insulator Heterostructures
Murod Mirzhalilov, Nandini Trivedi, Mohit Randeria
We theoretically analyze the topological insulator (TI) surface state mediated interactions between local moments in a proximate 2D ferromagnetic insulator (FMI) motivated by recen…
Charge Modulation in the Vortex Halo of a Superconductor Enhances its Critical Magnetic Field
Anurag Banerjee, Catherine Pépin, Nandini Trivedi +1
When an orbital magnetic field suppresses superconductivity, forming periodic vortices in type-II superconductors, subdominant orders can emerge in the vortex cores. Rather than co…
