Spin modulations in the Rashba-Hubbard chain -- a tensor network study
Jozef Genzor, Roman KrÄmár, Andrej Gendiar +2
Uniform spin-orbit coupling in an open single-band Hubbard chain is an exactly removable \(SU(2)\) gauge field at the Hamiltonian level, but not at the level of laboratory-frame sp…
Efficient Magnetic Spin-Filtering and Persistent Spin-Currents in Lifshitz-Transitioned Altermagnets: A Route to Open-Orbit Spintronics
Wun-Hao Kang, Yu-Ting Hsiao, Jozef Genzor +3
Altermagnets offer a unique venue for spin transport due to their vanishing net magnetization and momentum-dependent spin splitting. We demonstrate that a homotopic Lifshitz transi…
Scalable tight-binding model for strained graphene
Ming-Hao Liu, Christophe De Beule, Alina MreÅca-KolasiÅska +4
We generalize the scalable tight-binding model for graphene, which allows for efficient quantum transport simulations in the Dirac regime, to account for elastic strain. We show th…
Twisted superconducting quantum diodes: Towards anharmonicity and high fidelity
Han Zhong, Denis Kochan, Igor Zutic +1
As quantum technologies advance, a fundamental challenge is mitigating noise and backscattering in superconducting circuits to achieve scalable, high-fidelity operations. Conventio…
Phase Transition of the Ising Model on a 3-Dimensional Fractal Lattice
Jozef Genzor, Roman KrÄmár, Hiroshi Ueda +3
The critical behavior of the classical Ising model on a three-dimensional fractal lattice with Hausdorff dimension is investigated using the higher-order…
Pseudomagnetotransport in Strained Graphene
Alina MreÅca-KolasiÅska, Christophe De Beule, Jia-Tong Shi +4
In graphene, long-wavelength deformations that result in elastic shear strain couple to the low-energy Dirac electrons as pseudogauge fields. Using a scalable tight-binding model,…
