Relaxation of the Ising spin system coupled to a bosonic bath and the time dependent mean field equation
Máté Tibor Veszeli, Gábor Vattay
The Ising model doesn't have a strictly defined dynamics, only a spectrum. There are different ways to equip it with a time dependence e.g. the Glauber or the Kawasaki dynamics, wh…
Mean Field Approximation for solving QUBO problems
Máté Tibor Veszeli, Gábor Vattay
The Quadratic Unconstrained Binary Optimization (QUBO) problems are NP hard; thus, so far, there are no algorithms to solve them efficiently. There are exact methods like the Branc…
A Landauer Formula for Bioelectronic Applications
Eszter Papp, Dávid P. Jelenfi, Máté T. Veszeli +1
Recent electronic transport experiments using metallic contacts attached to proteins identified some 'stylized facts' which contradict conventional wisdom that increasing either th…
Fast electron spin flips via strong subcycle electric excitation
Máté Tibor Veszeli, András Pályi
An important goal in quantum information processing is to reduce the duration of quantum-logical operations. Motivated by this, we provide a theoretical analysis of electrically in…
