The Heckler’s Promise

From gluing audience members to their seats and purposefully selling the same ticket to more than one person, artists associated with the Historical Avant-Garde often sought to provoke and antagonise by employing disruption via interruptive processes. This paper responds to Claire Bishop’s call for more agonism (Bishop, 2004) by inserting the heckler as both method and object into art performance. It is a hybrid of practice and theory, statement and response, test and experiment; it is a combination of all these things because you can’t really envisage a heckler without taking him out for the night putting him in the world and observing the exchanges that take place. We think that practicing heckling has got to be worth the aggravation.  This paper seeks to do two things: first to explore the heckler as a ‘device’ for reassessing the potential of interruption in democratic exchange, in particular in relation to contemporary theories of art and participation and second to try it out; to put the heckler at the centre of an artwork. In short, we propose a rethinking of the heckler.  Part 1: Heckle, Hiss, Howl and Holler asks if there is something worth considering in the process of heckling for democratic exchange and, Part 2: Contract, Collaboration, Countdown and Confrontation strikes out to see what happens when you present an artwork that trials a performance about heckling via the act of heckling.  The inhospitable performance Contract with a Heckler demonstrates a complex knitting of theory and practice whereby argument is supported by the undertaking of action (by the necessity of experiencing interruption in practice) and reveals working with interruption on a theoretical, practical and emotional level can be exciting, provocative and dangerous. Exploring contractual agency through hostipitality (Derrida, 2000) wherein a host may be as hostile as she is hospitable, this performance reimagines the event of performance as an event of (in)hospitality by embodying an ambivalent conviviality and employing heckling to disrupt convivial participation (Bourriaud, 1998)

Quantum Algorithms for Fermionic Quantum Field Theories

Extending previous work on scalar field theories, we develop a quantum algorithm to compute relativistic scattering amplitudes in fermionic field theories, exemplified by the massive Gross-Neveu model, a theory in two spacetime dimensions with quartic interactions. The algorithm introduces new techniques to meet the additional challenges posed by the characteristics of fermionic fields, and its run time is polynomial in the desired precision and the energy. Thus, it constitutes further progress towards an efficient quantum algorithm for simulating the Standard Model of particle physics.Comment: 29 page

Quantum Algorithms for Quantum Field Theories

Quantum field theory reconciles quantum mechanics and special relativity, and plays a central role in many areas of physics. We develop a quantum algorithm to compute relativistic scattering probabilities in a massive quantum field theory with quartic self-interactions (phi-fourth theory) in spacetime of four and fewer dimensions. Its run time is polynomial in the number of particles, their energy, and the desired precision, and applies at both weak and strong coupling. In the strong-coupling and high-precision regimes, our quantum algorithm achieves exponential speedup over the fastest known classical algorithm.Comment: v2: appendix added (15 pages + 25-page appendix
