Quantum Phase Transitions [PDF]

, 2000
These are notes for lectures delivered at the NATO ASI on Dynamics in Leiden, The Netherlands, in July 1998. The main concepts relating to quantum phase transitions are explained, using the paramagnet-to-ferromagnet transition of itinerant electrons as the primary example. Some aspects of metal-insulator transitions are also briefly discussed.

Chaos controlled and disorder driven phase transitions induced by breaking permutation symmetry [PDF]

Scientific Reports
The effects of disorder and chaos on quantum many-body systems can be superficially similar, yet their interplay has not been sufficiently explored. This work finds a continuous phase transition when disorder breaks permutation symmetry, with details of ...

Phase transitions in random circuit sampling [PDF]

Nature, 2023
Undesired coupling to the surrounding environment destroys long-range correlations in quantum processors and hinders coherent evolution in the nominally available computational space. This noise is an outstanding challenge when leveraging the computation

Electro-Thermo-Convection of a Dielectric Liquid in the External DC and AC Electric Fields

Mathematics, 2023
The electro-thermo-convection of a dielectric liquid in a horizontal capacitor is investigated under the autonomous charge injection from the cathode and heating from above. In the case of a DC electric field, the linear stability analysis is carried out,

Entanglement Phase Transitions in Measurement-Only Dynamics [PDF]

Physical Review X, 2020
Unitary circuits subject to repeated projective measurements can undergo an entanglement transition as a function of the measurement rate. This transition is generally understood in terms of a competition between the scrambling effects of unitary ...

Detecting gravitational waves from cosmological phase transitions with LISA: an update [PDF]

Journal of Cosmology and Astroparticle Physics, 2019
We investigate the potential for observing gravitational waves from cosmological phase transitions with LISA in light of recent theoretical and experimental developments. Our analysis is based on current state-of-the-art simulations of sound waves in the
