Presentation

The "Theory of light-matter and quantum phenomena" (RMPQ) group has been founded to promote theoretical studies on elementary and collective quantum effects, at the crossroads between light-matter physics, condensed matter, and ultra-cold quantum gases.

RMPQ is the theory group of the "PEPS division".

Group activities are developed in close collaboration with several national and international experimental groups, and are motivated by both fundamental and applicative challenges in quantum physics.

Main group research activities, conducted by means of analytical and advanced numerical tools in theoretical physics, are :

non-equilibrium dynamics in quantum physics (Casimir-Lifshiz interaction, heat transfer, fluctuations-dissipation theorems, entanglement, light-harvesting complexes, quantum thermal machines)

light and energy transport properties in periodic or disordered quantum complex systems (ultra cold quantum gases, quantum dots, photonics crystals, artificial atomic crystals, graphene)

few and many-body quantum physics (Bose-Einstein condensation, collective oscillations, solitons, and quantum vortices in Bose and Fermi atomic gases, polaritons in semiconductors)

plasmonics and nanophotonics (graphene, gratings, numerical electromagnetism)

Résumé:

Phase change materials (PCMs) play a pivotal role in the development of advanced thermal devices due to their reversible phase transitions, which drastically modify their thermal and optical properties. In this study, we present an effective dynamic thermal transistor with an asymmetric design that employs distinct PCMs, vanadium dioxide (VO₂) and germanium antimony telluride (GST), on either side of the gate terminal, which is the center of the control unit of the near-field thermal transistor. This asymmetry introduces unique thermal modulation capabilities, taking control of thermal radiation in the near-field regime. VO₂ transitions from an insulating to a metallic state, while GST undergoes a reversible switch between amorphous (aGST) and crystalline (cGST) phases, each inducing substantial changes in thermal transport properties. By strategically combining these materials, the transistor exhibits enhanced functionality, dynamically switching between states of absorbing and releasing heat by tuning the temperature of gate. This gate terminal not only enables active and efficient thermal management but also provides effective opportunities for manipulating heat flow in radiative thermal circuits. Our findings highlight the potential of such asymmetrically structured thermal transistors in advancing applications across microelectronics, high-speed data processing, and sustainable energy systems, where precise and responsive thermal control is critical for performance and efficiency.

In recent years, the development of near-field radiative heat transfer (NFRHT) technology has provided strong support for breaking through the bottleneck of traditional thermal management methods. 1,2 Near-field radiation can achieve radiant heat transfer above the blackbody limit at very short distances, to achieve efficient heat exchange and regulation at the nanoscale. 3 The core of this kind of technology lies in the precise tuning of the radiation characteristics of the material, and PCM has gradually become the ideal material choice for the realization of micro-nano thermal control devices because of its unique phase transition ability and repeatable thermo-optical properties. 4,5,6 Near-field thermal diodes and thermal transistors are two key components in thermal management systems 7 , and their working principle is similar to that of electrical diodes and transistors in electronic
