Fundamental Challenges, Physical Implementations, and Integration Strategies for Ising Machines in Large‐Scale Optimization Tasks

Advanced Electronic Materials, EarlyView.
Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

Phase diagram of the Hubbard model on the anisotropic triangular lattice

, 2015
We investigate the Hubbard model on the anisotropic triangular lattice as a suggested effective description of the Mott phase in various triangular organic compounds. Employing the variational cluster approximation and the ladder dual-fermion approach as

Beyond extended dynamical mean-field theory: Dual boson approach to the two-dimensional extended Hubbard model [PDF]

, 2014
The dual boson approach [Ann. Phys. 327, 1320 (2012)] provides a means to construct a diagrammatic expansion around the extended dynamical mean-field theory (EDMFT).

Parquet solution for a flat Fermi surface

, 1996
We study instabilities occurring in the electron system whose Fermi surface has flat regions on its opposite sides. Such a Fermi surface resembles Fermi surfaces of some high-$T_c$ superconductors.

Spontaneous Magnon Decays [PDF]

, 2013
A theoretical overview of the phenomenon of spontaneous magnon decays in quantum antiferromagnets is presented. The intrinsic zero-temperature damping of magnons in quantum spin systems is a fascinating many-body effect, which has recently attracted ...

String order in dipole-blockaded quantum liquids [PDF]

, 2014
We study the quantum melting of quasi-one-dimensional lattice models in which the dominant energy scale is given by a repulsive dipolar interaction. By constructing an effective low-energy theory, we show that the melting of crystalline phases can occur ...

Exact dynamics of concurrence-based entanglement in a system of four spin-1/2 particles on a triangular ladder structure [PDF]

Physica Scripta, 2019
Motivated by the ability of triangular spin ladders to implement quantum information processing, we propose a type of such systems whose Hamiltonian includes the XX Heisenberg interaction on the rungs and DzyaloshinskiiMoriya (DM) coupling over the legs.

Operational Performance Implications of Circular Economy Implementation: An Empirical Exploration in the Manufacturing Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT The global manufacturing sector has increasingly adopted circular economy (CE) practices to address sustainability challenges and improve operational efficiency. This study explores the impact of five CE practices—reduce, reuse, remanufacture, recycle, and recover—on key operational performance dimensions: quality, speed, dependability ...

Bipolaron Density-Wave Driven By Antiferromagnetic Correlations and Frustration in Organic Superconductors

, 2009
We describe the Paired Electron Crystal (PEC) which occurs in the interacting frustrated two-dimensional 1/4-filled band. The PEC is a charge-ordered state with nearest-neighbor spin singlets separated by pairs of vacant sites, and can be thought of as a
