Spin and charge order in doped spin-orbit coupled Mott insulators
Mehdi Biderang, Alireza Akbari, Jesko Sirker
We study a two-dimensional single band Hubbard Hamiltonian with antisymmetric spin-orbit coupling. We argue that this is the minimal model to understand the electronic properties o…
Floquet dynamical phase transition and entanglement spectrum
R. Jafari, Alireza Akbari
We explore both pure and mixed states Floquet dynamical quantum phase transitions (FDQFTs) in the one-dimensional p-wave superconductor with a time-driven pairing phase. In the Fou…
Optical and magnetic excitations in the underscreened quasi-quartet Kondo lattice
Alireza Akbari, Peter Thalmeier
The underscreened Kondo lattice consisting of a single twofold degenerate conduction band and a CEF split 4f-electron quasi-quartet has non-conventional quasiparticle dispersions o…
Field-angle resolved magnetic excitations as a probe of hidden-order symmetry in CeB6
P. Y. Portnichenko, A. Akbari, S. E. Nikitin +17
In contrast to magnetic order formed by electrons' dipolar moments, ordering phenomena associated with higher-order multipoles (quadrupoles, octupoles, etc.) are more difficult to…
Geometrically Frustrated Anisotropic Four-Leg Spin- Nanotube
R. Jafari, Saeed Mahdavifar, Alireza Akbari
We develop a real space quantum renormalization group (QRG) to explore a frustrated anisotropic four-leg spin-1/2 nanotube in the thermodynamic limit. We obtain the phase diagram,…
Heavy quasiparticle bands in the underscreened quasiquartet Kondo lattice
Peter Thalmeier, Alireza Akbari
We study the quasiparticle spectrum in an underscreened Kondo-lattice (KL) model that involves a single spin degenerate conduction band and two crystalline-electric-field (CEF) spl…
