Magnon polarons
A magnon polaron is a hybrid quasiparticle formed when a magnon and a phonon couple through magnetoelastic interaction, marked by an anticrossing in their dispersion relations.
Magnon spin Nernst effect
The magnon spin Nernst effect is the generation of a transverse pure spin current carried by magnons when a temperature gradient is applied to a magnetic material.
Magnon valleytronics
Magnon valleytronics is a research field that encodes information in the valley index of magnons, combining magnonics with valleytronics; a magnon valley Hall effect was reported in CrI3 in 2020.
Magnon valve
A magnon valve is a three-layer spintronic device, typically YIG/Au/YIG, whose magnon current is transmitted or attenuated depending on the magnetization alignment of two magnetic layers.
Magnon–qubit strong coupling
Magnon–qubit strong coupling is the regime where a magnon coherently exchanges energy with a qubit, first demonstrated in 2014 using a YIG sphere in a microwave cavity.
Magnonics
Magnonics is the field of physics and engineering concerned with generating, propagating, manipulating, and detecting spin waves and their quanta, magnons, in magnetically ordered materials, promising low-power computing.
Magnus effect
The Magnus effect, or Magnus force, is the sideways force on a spinning object moving through a fluid, named for Heinrich Gustav Magnus, who studied it in 1853.
Magnus expansion
The Magnus expansion, introduced by Wilhelm Magnus in 1954, expresses the solution of linear differential equations with time-dependent coefficients as the exponential of nested commutators, widely used in quantum mechanics and NMR.
Magnus Rueping
Magnus Rueping is an organic chemist and professor at King Abdullah University of Science and Technology in Saudi Arabia, known for asymmetric Brønsted acid organocatalysis and metallaphotoredox catalysis.
Magura Fossae
Magura Fossae is a 600-km-wide fossa (tectonic trough) system on Venus at 12°S, 332.5°E, in quadrangle v43; IAU-approved in 1997 and named for an East Slavic winged warrior maiden.
Mahalanobis distance
The Mahalanobis distance is a statistical measure of distance between a point and a distribution that accounts for correlations among variables, introduced by P. C. Mahalanobis in 1936.
Maharashtra floods of 2005
The Maharashtra floods of 2005, also called the Mumbai Mega Flood, killed about 1,094 people after Mumbai recorded 944.2 mm of rain in 24 hours on 26 July.
Mahaviracharya
Mahaviracharya was a 9th-century Indian Jain mathematician who wrote during the reign of Amoghavarsha and composed the Ganitasarasangraha, the earliest surviving Indian text devoted entirely to mathematics.
Mahdi M. Abu‐Omar
Mahdi M. Abu-Omar is an American chemist, Mellichamp Endowed Chair in Green Chemistry at UC Santa Barbara, known for lignin-first biorefining, rhenium-catalyzed deoxydehydration, and founder of Spero Renewables.
Mahito Kohmoto
Mahito Kohmoto is a Japanese condensed matter physicist at the Institute for Solid State Physics, University of Tokyo, co-author of the 1982 TKNN paper explaining quantized Hall conductance topologically.
Mahlo cardinal
A Mahlo cardinal, also called a strongly Mahlo cardinal, is a large cardinal that is inaccessible and a stationary limit of regular cardinals, introduced by Paul Mahlo in 1911.
Mahonian statistic
A Mahonian statistic is a statistic on permutations whose distribution equals that of the inversion number; the major index is the other prototype, both named for Percy MacMahon.
Maia (star)
Maia (20 Tauri) is the fourth-brightest star of the Pleiades in Taurus, a chemically peculiar blue-white B-type giant of magnitude 3.87 that rotates far more slowly than its bright neighbors.
Maiken H. Mikkelsen
Maiken H. Mikkelsen, also known as Maiken Mikkelsen, is a physicist who leads nanophotonics research at Duke University, known for plasmonic nanoantennas and ultrafast single-photon sources.
Main Central Thrust
The Main Central Thrust (MCT) is a major thrust fault running nearly the entire length of the Himalaya, first named by Heim and Gansser in 1939.
Main sequence
The main sequence is the stage of a star's life in which it stably fuses hydrogen into helium in its core; most stars, including the Sun, are in it.
Main-belt comet
A main-belt comet (MBC) is a small Solar System body in the main asteroid belt between Mars and Jupiter showing comet-like activity from sublimating ice, first recognized as a class in 2006.
Main-group organo derivatives
Main-group organo derivatives are organic compounds containing main-group elements such as boron, silicon, phosphorus, arsenic, antimony, selenium, and tellurium, whether or not the element is directly bonded to carbon.
Majed Chergui
Majed Chergui is a Moroccan-born physicist recognized for pioneering ultrafast X-ray and deep-UV spectroscopy. He is Professor Emeritus at EPFL and leads the CHIRAX project in Trieste, Italy.
Major adverse cardiovascular events
Major adverse cardiovascular events, also expanded as major adverse cardiac events (MACE), is a composite clinical trial endpoint combining cardiovascular death, nonfatal myocardial infarction, and stroke.
Majorana Demonstrator
The Majorana Demonstrator was a neutrino physics experiment at the Sanford Underground Research Facility in South Dakota that searched for neutrinoless double-beta decay of germanium-76.
Majorana fermion
A Majorana fermion, or Majorana particle, is a hypothetical spin-1/2 particle identical to its own antiparticle, proposed by Italian physicist Ettore Majorana in 1937; no elementary one has been confirmed.
Majorana island
A Majorana island is a small superconducting island, or quantum dot, that hosts pairs of Majorana zero modes and is a proposed building block for topological qubits.
