Classical analog circuit emulation of quantum Grover search algorithm
Samuel Feldman, Hassam Ghazali, Andrey Rogachev
We construct a completely analog framework that emulates universal quantum gates and quantum algorithms. It is based on electronic circuits made of operational amplifiers, resistor…
Quantum phase transition in small-size 1d and 2d Josephson junction arrays: analysis of the experiments within the interacting plasmons picture
Samuel Feldman, Andrey Rogachev
Theoretically, Josephson junction (JJ) arrays can exhibit either a superconducting or insulating state, separated by a quantum phase transition (QPT). In this work, we analyzed pub…
Quantum phase transitions in quantum Hall and other topological systems: role of the Planckian time
Andrey Rogachev
Transformations between the plateau states of the quantum Hall effect (QHE) are an archetypical example of quantum phase transitions (QPTs) between phases with non-trivial topologi…
Microscopic scale of quantum phase transitions: from doped semiconductors to spin chains, cold gases and moiré superlattices
Andrey Rogachev
In the vicinity of continuous quantum phase transitions (QPTs), quantum systems become scale-invariant and can be grouped into universality classes characterized by sets of critica…
Microscopic scales and mechanism of quantum phase transitions in two-dimensional superconducting systems
Andrey Rogachev, Samuel Feldman, Kevin Davenport
The superconducting ground state in many two-dimensional materials can be created or destroyed through quantum phase transitions (QPTs) controlled by non-thermal parameters such as…
Hall coefficient in amorphous alloys: critical behavior and quantitative test of quantum corrections due to weak localization and electron-electron interactions
A. Rogachev, H. Ikuta, U. Mizutani
Here, we present the measurements of in a series of amorphous reaching the critical concentration, . For , the Hall coefficient dis…
