Antics (album)
Antics is Interpol's second studio album, released September 2004 on Matador Records; recorded with Peter Katis in Connecticut, it scored 80 on Metacritic, peaked at UK number 21, and spawned "Evil" and "Slow Hands".
Antidepressant
Antidepressants are prescription medicines, mainly SSRIs, SNRIs, NDRIs, TCAs, and MAOIs, used to treat depression and also anxiety, pain, and insomnia; they take 4 to 8 weeks to work and all beat placebo in a 2018 meta-analysis of 522 trials.
Antidepressant discontinuation syndrome
Antidepressant discontinuation syndrome, also called antidepressant withdrawal, causes dizziness, brain zaps, insomnia and flu-like symptoms 36–96 hours after stopping SSRIs, SNRIs, TCAs, or MAOIs; roughly 15% placebo-attributable incidence, worst with paroxetine and venlafaxine, managed by slow hyperbolic tapering per NICE 2023.
Antidepressants (album)
Antidepressants is Suede's tenth studio album, released 5 September 2025 on BMG. Recorded live with producer Ed Buller as a post-punk follow-up to Autofiction, it reached No. 2 in the UK and earned an 84.2/100 review consensus.
Antiderivative
An antiderivative, also called an indefinite integral, is a differentiable function F whose derivative F′ equals a given function f; any two antiderivatives differ only by a constant C.
Antidio Fagúndez Campo
Antidio Fagúndez Campo is a Spanish Socialist Workers' Party politician, a deputy for Zamora since 2023 and chair of the Congress committee on democratic quality and anti-corruption reforms.
Antidisestablishmentarianism
Antidisestablishmentarianism is opposition to the disestablishment of the Church of England, in practice the movement that defended the church's union with the state in Wales until disestablishment took effect on 31 March 1920.
Antidote
An antidote is an agent that counteracts a poison by neutralizing it chemically, competing at receptors, or speeding elimination. Examples include naloxone for opioids, atropine, and activated charcoal.
Antiemetic
Antiemetic: drug class preventing or treating nausea and vomiting. Includes 5-HT3 antagonists (ondansetron), dopamine antagonists (metoclopramide), NK1 antagonists, antihistamines, steroids; used in chemotherapy, surgery, pregnancy, gastroenteritis.
Antifa (Germany)
Antifa (Germany): decentralized spectrum of autonomous antifascist groups, named after the KPD's 1932 Antifaschistische Aktion; revived in 1980s West Germany, peaked 1989/90 to mid-1990s; partly observed by the BfV as left-wing extremism.
Antifa (United States)
Antifa in the United States is a decentralized, leaderless left-wing anti-fascist movement of autonomous local groups, tracing to 1980s punk and anarchist organizing, employing doxxing and protest tactics, assessed by CSIS as a relatively small threat, and designated by executive order in 2025.
Antifaschistische Aktion
Antifaschistische Aktion (Antifascist Action): KPD-founded militant anti-fascist united front of May 1932 in Weimar Germany, source of the two-flags antifa emblem, suppressed in 1933 and revived by autonomous antifa from the 1980s.
Antifeminism
Antifeminism is opposition to feminism and feminist policies in some or all forms, theorized as a countermovement to feminist movements. Distinct from misogyny and sexism, it spans conservative anti-ERA activism, the anti-gender movement, far-right 'gender ideology' discourse, and online manosphere and tradwife influencers.
Antiferroelectric Hf0.5Zr0.5O2
Antiferroelectric Hf0.5Zr0.5O2 is the antiferroelectric-like behavior of hafnium zirconium oxide thin films, where applied electric fields drive a reversible transition between nonpolar and polar phases, yielding double hysteresis loops.
Antiferroelectric nematic phase
An antiferroelectric nematic phase is a proposed liquid-crystal state in which strongly polar rod-like molecules keep nematic orientational order while their dipoles arrange antiparallel, appearing between the nonpolar and ferroelectric nematics.
Antiferroelectricity
Antiferroelectricity is a property of crystals whose dipoles are arranged antipolar, giving zero net polarization that switches to a polar state under an electric field.
Antiferromagnetic memory
Antiferromagnetic memory is an experimental non-volatile memory that stores bits in the Néel vector of an antiferromagnet, promising faster, denser devices than ferromagnetic MRAM; laboratory demonstrations include picosecond switching.
Antiferromagnetic memory switching
Antiferromagnetic memory switching is the electrical, optical, or thermal reversal of an antiferromagnet's magnetic order to store information, with picosecond current-pulse writing demonstrated in CuMnAs.
Antiferromagnetic resonance
Antiferromagnetic resonance (AFMR), described theoretically by Kittel in the late 1940s, is the precession of the Néel vector in antiferromagnets at terahertz frequencies, useful for spintronic oscillators and magnon logic.
Antiferromagnetic skyrmion
An antiferromagnetic skyrmion is a nanoscale, topologically protected whirling spin texture in an antiferromagnetic material, first proposed in theory in 2016 and studied for spintronic racetrack memory.
Antiferromagnetic skyrmions in IrMn
Antiferromagnetic skyrmions in IrMn are nanoscale magnetic vortices in the antiferromagnet iridium manganese, first directly created in 2024 and pursued as information carriers for high-density, low-power spintronic memory.
Antiferromagnetic spintronics
Antiferromagnetic spintronics is a branch of spintronics in which antiferromagnets, internally magnetic but externally invisible, serve as active elements for faster, denser, more field-robust memory.
Antiferromagnetic THz spintronics
Antiferromagnetic THz spintronics is a branch of spintronics, using electron spin rather than charge, in which antiferromagnets are controlled and detected at terahertz frequencies for ultrafast devices.
Antiferromagnetic topological insulator
An antiferromagnetic topological insulator is a magnetic insulator whose band structure is topologically nontrivial despite zero net magnetization, defined theoretically in 2010 and first realized in MnBi2Te4.
Antiferromagnetic tunnel junctions
An antiferromagnetic tunnel junction is a spintronic device in which a thin insulating barrier, typically MgO, separates two antiferromagnetic electrodes, with resistance depending on the relative orientation of their antiferromagnetic order.
Antiferromagnetism
Antiferromagnetism is magnetic ordering in which neighboring atomic moments align antiparallel, so the material has zero net magnetization; it appears below a critical temperature called the Néel temperature.
Antifoam additive
An antifoam additive, also called a defoamant or antifoaming agent, prevents oil from foaming and speeds foam collapse, typically dosed at 10 to 250 parts per million.
Antifragile (album)
Antifragile (album) refers to two releases: All That Remains' tenth studio album, an independent 2025 metalcore record, and ANTIFRAGILE, LE SSERAFIM's 2022 second mini album on Source Music.
Antifreeze
Antifreeze is a chemical added to water-based fluids to lower their freezing point, chiefly solutions of ethylene glycol or propylene glycol used as engine coolants and aircraft deicing fluids.
Antifungal
Antifungals are antimicrobial drugs (azoles, echinocandins, polyenes, terbinafine, flucytosine, ibrexafungerp) that target fungal ergosterol, its synthesis, or the cell wall. Only three main classes treat invasive infections, and resistance is rising.
