Real and momentum space analysis of topological phases in 2D d-wave altermagnets
Manuel Calixto
Altermagnetism has recently emerged as a third fundamental branch of magnetism, combining the vanishing net magnetization of antiferromagnets with the high-momentum-dependent spin…
Highly robust logical qubit encoding in an ensemble of V-symmetrical qutrits
Luis Octavio Castaños-Cervantes, Manuel Calixto, Julio Guerrero
We propose using even and odd Schödinger cat states formed from coherent states of U(3) of an ensemble of qutrits with a symmetrical V-configuration (a qubit-disguised qutrit) to…
Localization and entanglement characterization of edge states in HgTe quantum wells in a finite strip geometry
Manuel Calixto, Octavio Castaños
Quantum information measures are proposed to analyze the structure of near-gap electronic states in HgTe quantum wells in a strip geometry o…
Wigner quasi-probability distribution for symmetric multi-quDit systems and their generalized heat kernel
Manuel Calixto, Julio Guerrero
For a symmetric -quDit system described by a density matrix , we construct a one-parameter family of quasi-probability distributions through gener…
Lieb-Mattis ordering theorem of electronic energy levels in the thermodynamic limit
Manuel Calixto, Alberto Mayorgas, Julio Guerrero
Lieb-Mattis theorem orders the lowest-energy states of total spin of a system of interacting fermions. We generalize these predictions to fermionic mixtures of particle…
Capturing magic angles in twisted bilayer graphene from information theory markers
Manuel Calixto, Alberto Mayorgas, Octavio Castaños
Zero energy eigenstates of the twisted bilayer graphene Hamiltonian at the Dirac point show a high sensitivity to the twist angle near the magic angles where the ef…
