A transition in the hole probability at finite temperature for free fermions in dimensions
Giuseppe Del Vecchio Del Vecchio, Pierre Le Doussal, Gregory Schehr
In a free Fermi gas at temperature much higher than the Fermi temperature one expects that the fluctuations of the number of particles in a given region has Poissonian/classica…
Sluggish quantum mechanics of noninteracting fermions with spatially varying effective mass
Giuseppe Del Vecchio Del Vecchio, Manas Kulkarni, Satya N. Majumdar +1
We analyze a class of one-dimensional quantum systems characterized by a position-dependent kinetic term arising as the continuum limit of an inhomogeneous tight-binding model with…
Observing quantum phase transitions at non-zero temperature: non-analytic behavior of order-parameter correlation times
István Csépányi, Giuseppe Del Vecchio Del Vecchio, Benjamin Doyon +1
Phase transitions occur when a macroscopic number of local degrees of freedom coherently change their behavior. In ground states of quantum many-body systems, phase transitions due…
Universal Random Matrix Behavior of a Fermionic Quantum Gas
Maxime Dixmerias, Giuseppe Del Vecchio Del Vecchio, Cyprien Daix +6
The pursuit of universal governing principles is a foundational endeavor in physics, driving breakthroughs from thermodynamics to general relativity and quantum mechanics. In 1951,…
