Theoretical investigation of superconductivity in trilayer square-planar nickelates
Emilian M. Nica, Jyoti Krishna, Rong Yu +3
The discovery of superconductivity in Sr-doped NdNiO is a crucial breakthrough in the long pursuit for nickel oxide materials with electronic and magnetic properties similar…
Kondo effect due to a hydrogen impurity in graphene: a multichannel Kondo problem with diverging hybridization
Zheng Shi, Emilian M. Nica, Ian Affleck
We consider the Kondo effect arising from a hydrogen impurity in graphene. As a first approximation, the strong covalent bond to a carbon atom removes that carbon atom without brea…
Interacting Majorana fermions in strained nodal superconductors
Emilian M. Nica, Onur Erten
Landau levels (LL) have been predicted to emerge in systems with Dirac nodal points under applied non-uniform strain. We consider 2D, singlet (2D-S) and 3D equ…
Quantum criticality and global phase diagram of an Ising-anisotropic Kondo lattice
Emilian M. Nica, Kevin Ingersent, Qimiao Si
Recent studies of heavy-fermion systems with tunable quantum fluctuations have focused on a variety of zero-temperature phase transitions that involve not only the onset of magneti…
