We introduce a tensor network algorithm for the solution of p-spin models. We show that bond compression through rank-revealing decompositions performed during the tensor network contraction resolves logical redundancies in the system exactly and is

The role of exchange interactions in the dynamics of collective excitations in magnetic materials is of essential importance, and since the experimental discovery of planar ferromagnetism, a flurry of research has rapidly reshaped the field of 2D mat

For high-voltage shunt reactors with rods with non-magnetic gaps, an analytical method for calculating magnetic fluxes based on substitute circuits has been developed by substantiation by finite element modeling, and the calculation of main and addit

Untethered small‐scale helical devices (USHDs) have the potential to navigate blood vessels and treat vascular occlusive diseases. However, there are still many challenges in translating this method into clinical practice, both in terms of localiza

The field of magnetic robotics aims to obviate physical connections between the actuators and end‐effectors. Such tetherless control may enable new ultraminimally invasive surgical manipulations in clinical settings. While wireless actuation offers

Motivated by the compound LiHo_xY_(1-x)F_4, we consider the Ising chain with random couplings and in the presence of simultaneous random transverse and longitudinal fields, and study its low-energy properties at zero temperature by the strong disorde

Abstract It is difficult to measure the magnetisation characteristics of magnetic powder cores with small loss angle and high saturation flux density. Here, a new pulse measurement method is proposed, in which the capacitance with preset bias voltage

This article presents the results of a study on the dynamics of a volume of magnetic fluid levitating in a uniform magnetic field of an electromagnet experiencing an oscillatory shift. Samples with different physical parameters were considered, and t
