LONELY HEARTS
Ginzburg Seeks Ticker, Views Negotiable
A word appearing everywhere from superconductors to combinatorics still has nowhere to trade.
GINZBURG, surname turned common noun, logged 24 papers this week, up 153% on a usual 10, seeks a ticker for long walks through condensed matter and number theory alike.
Enjoys topological defect trains, as in "Topological defect trains excited by a boundary discontinuity in the two-dimensional complex Ginzburg-Landau equation".
Equally at home in combinatorics: see "On the Erdős--Ginzburg--Ziv Problem for Z_n^r".
Also dabbles in algebraic geometry, per "Existence of weak Landau-Ginzburg models for weighted complete intersections". No ticker, no dividend, just devotion.
STILL CLIMBING
Plasma Physics Keeps Running Hot After Its Turn in Charge
Up 66% since it topped this page, and it isn't travelling alone.
Plasma Physics (physics.plasm-ph) logged 48 papers this week, up 66% on a usual 29, having topped this page on 31 October and showing no sign of cooling.
Mathematical Physics (math-ph), itself a leader back on 28 October, stays warm: 77 papers this week, up 57% on a usual 49.
Superconductivity (cond-mat.supr-con), which had its own spell at the top on 30 October, keeps pace too: 41 papers this week, up 46% on a usual 28.
Information Retrieval (cs.IR) joins in without ever having led: 93 papers this week, up 41% on a usual 66, apparently deciding an encore needn't wait for an invitation.
THE EXCHANGE · $ANTN
Antenna Rings Up 10.5%, Hamiltonian Drops 8.8%
A loud day for antennas and uncrewed aircraft, a bruising one for anything named Hamiltonian.
$ANTN (antenna) led the day's gainers, up 10.5%, with $RICCI (ricci) up 1.7% and $UAV (uav) up 0.8% also higher.
$HAML (hamiltonian) took the worst of it, down 8.8%, with $HOLO (holographic) off 2.1% and $GRPH (graphene) down 1.8% also marked lower.
$AGNT (agent) kept its usual post as the busiest counter, with 560 hits across titles and abstracts on the day dividends were paid at the bell.
FUND DESK · $RICCI
Co-Author Network Sells $RICCI
Co-Author Network sold 4,754.05 credits of $RICCI, the desk can confirm.
A fund representative, who is a Python process, said: "Where one word goes, its co-authors follow."
Elsewhere on the fund desk: Co-Author Network sold $HAML and Citation Cartel Capital bought $AXN.

QUIET CORNER
Machine Learning Turns the Volume Down, Off 38%
cs.LG posted the steepest fall on the board, with company close behind it.
Machine Learning (cs.LG) logged 685 papers this week, down 38% on a usual 1,112, the steepest drop among the fields tracked.
Computation and Language (cs.CL) eased almost as far, down 37% to 345.
Sound (cs.SD) slipped 34% to 60, and Artificial Intelligence (cs.AI) rounded out the hush, down 33% at 512.
Four corners of arXiv, each minding its own business, all decided this was a week to read rather than write.
BREAKOUT · $VRTX
Vortices Spin Up 96%, Ticker and All
The word turned up across optics and superconductivity alike, well above its usual pace.
Mentions of "vortices" are up 96%: 27 papers used the word this week, well above the usual 14.
"On the gauge-invariant orbital angular momentum of vector optical vortices in the paraxial approximation and beyond" (physics.optics) keeps things spinning in light.
"Majorana Zero Modes in Fractional Vortices" (cond-mat.supr-con) finds them in superconductors instead.
"Local Josephson response near nonmagnetic impurities and vortices in a two-orbital s± superconductor" closes the loop. It trades as $VRTX, so admirers can finally put credits where their curiosity is.
From the arXiv papers settled on Thursday 29 October. Every figure is taken from the counts.
