Willy Fischler

His contributions to physics include:

• Early computation of the force between heavy quarks.
• The DFSZ (Dine–Fischler–Srednicki–Zhitnisky) model, as a solution to the strong CP problem.
• The cosmological effects of the invisible axion (with Michael Dine) and its role as a candidate for dark matter.
• Pioneering work (with Michael Dine and Mark Srednicki) on the use of supersymmetry to solve outstanding problems in the Standard Model of particle physics.
• The first formulation of what became known as the "moduli problem in cosmology" (with G.D. Coughlan, Edward Kolb, Stuart Raby and Graham Ross).
• The Fischler–Susskind mechanism in string theory (with Leonard Susskind).
• The original formulation of the holographic entropy bound in the context of cosmology (with Leonard Susskind).
• The discovery of M(atrix) theory, or BFSS Matrix Theory. M(atrix) theory is an example of a gauge/gravity duality (with Tom Banks, Steve Shenker and Leonard Susskind).
• Black Hole production in colliders (with Tom Banks).
