Mott correlations in ABC graphene trilayer aligned with hBN

M. J. Calderón, A. Camjayi, E. Bascones

The nature of the correlated phases found in some graphene heterostructures is under debate. We use dynamical mean-field theory (DMFT) to analyze the effect of local correlations c…

Spin-orbit effects surfacing on manganites

S. Valencia, M. J. Calderón, L. López-Mir +6

Spin-orbit coupling in magnetic systems lacking inversion symmetry can give rise to non trivial spin textures. Magnetic thin films and heterostructures are potential candidates for…

Signatures of atomic-scale structure in the energy dispersion and coherence of a Si quantum-dot qubit

J. C. Abadillo-Uriel, Brandur Thorgrimsson, Dohun Kim +11

We report anomalous behavior in the energy dispersion of a three-electron double-quantum-dot hybrid qubit and argue that it is caused by atomic-scale disorder at the quantum-well i…

Orbital differentiation and the role of orbital ordering in the magnetic state of Fe superconductors

E. Bascones, B. Valenzuela, M. J. Calderón

We analyze the metallic (pi,0) antiferromagnetic state of a five-orbital model for iron superconductors. We find that with increasing interactions the system does not evolve trivia…

Intervalley coupling for interface-bound electrons in silicon: An effective mass study

A. L. Saraiva, M. J. Calderón, Rodrigo B. Capaz +3

Orbital degeneracy of the electronic conduction band edge in silicon is a potential roadblock to the storage and manipulation of quantum information involving the electronic spin d…

Physical mechanisms of interface-mediated intervalley coupling in Si

A. L. Saraiva, M. J. Calderón, Xuedong Hu +2

The conduction band degeneracy in Si is detrimental to quantum computing based on spin qubits, for which a nondegenerate ground orbital state is desirable. This degeneracy is lifte…

The current spin on manganites

C. Israel, M. J. Calderón, N. D. Mathur

In a material, the existence and coexistence of phases with very different magnetic and electronic properties is both unusual and surprising. Manganites in particular capture the i…
