Amsterdam, Noord-Holland, Nederland AMOLF Voltijd
Research Position in Nanomechanical Computing

Background

The energy consumption of computers is a significant scientific and societal challenge. Information technology is responsible for more CO2 emissions than the airline industry. At the fundamental level, the energy cost of a computation is dictated by the laws of thermodynamics. Establishing an arrow of time requires consuming free energy. The problem of quantifying the energy cost of computers is the domain of stochastic thermodynamics, a sub-field of statistical physics focused on small systems far from equilibrium.

Key Challenge and Approach

Experimentally probing the energy limits of computers is challenging. We plan to tackle this challenge by building nanomechanical computers that process information using very small structures that can bend under tiny forces. We will actuate the nanostructures using optical forces and measure them using custom, on-chip optical interferometers to quantify the energy consumption.

Key Tasks

The Ph.D. position will be primarily experimental. The student will be tasked with fabricating nanomechanical bits and logic gates and experimentally studying their evolution. Occasional numerical simulations will be conducted to help interpret and contextualize the results.

Qualifications

We are looking for an experimentally-minded student with a MSc degree in physics or engineering. Experience in cleanroom nanofabrication, optomechanics, or stochastic thermodynamics is a plus but not required. Perseverance and willingness to take on challenging experiments is a must.

Work Environment

AMOLF is a part of NWO-I and performs leading fundamental research on the physics of complex forms of matter. The institute is located at Amsterdam Science Park and currently employs about 140 researchers and 80 support employees.

What We Offer

We are a diverse and international research group, with a supportive and collaborative atmosphere, working on the growing field of information processing in physical systems. The group is hosted in a vibrant department focused on information processing across diverse platforms. Our institute is equipped with a state-of-the-art, on-site cleanroom. The Ph.D. includes funding to attend several international conferences.

Working Conditions

  • The working atmosphere at the institute is largely determined by young, enthusiastic, mostly foreign employees.
  • The position is intended as full-time (40 hours/week, 12 months/year) appointment in the service of the Netherlands Foundation of Scientific Research Institutes (NWO-I) for the duration of four years.
  • The starting salary is 2,781 Euros gross per month, and a range of employment benefits.
  • After successful completion of the PhD research, a PhD degree will be granted at a Dutch University.
  • Several courses are offered, specially developed for PhD-students.
  • AMOLF assists any new foreign PhD-student with housing and visa applications and compensates their transport costs and furnishing expenses.
