Electrically-driven amplification of terahertz acoustic waves in graphene
Aaron H. Barajas-Aguilar, Jasen Zion, Ian Sequeira +6
In graphene devices, the electronic drift velocity can easily exceed the speed of sound in the material at moderate current biases. Under this condition, the electronic system can…
Solvable models for 2+1D quantum critical points: Loop soups of 1+1D conformal field theories
Amin Moharramipour, Dan Sehayek, Thomas Scaffidi
We construct a class of solvable models for 2+1D quantum critical points by attaching 1+1D conformal field theories (CFTs) to fluctuating domain walls forming a ``loop soup''. Spec…
Minimal model for the flat bands in copper-substituted lead phosphate apatite: Strong diamagnetism from multi-orbital physics
Omid Tavakol, Thomas Scaffidi
The claims that a copper-substituted lead apatite, denoted as CuPb(PO)OH, could be a room-temperature superconductor have led to an intense research activity. While…
Magnetization amplification in the interlayer pairing superconductor 4Hb-TaS
Chunxiao Liu, Shubhayu Chatterjee, Thomas Scaffidi +2
A recent experiment on the bulk compound 4Hb-TaS reveals an unusual time-reversal symmetry-breaking superconducting state that possesses a magnetic memory not manifest in the n…
Surprises in the Deep Hilbert Space of all-to-all systems: From super-exponential scrambling to slow entanglement growth
Zihao Qi, Thomas Scaffidi, Xiangyu Cao
The quantum dynamics of spin systems with uniform all-to-all interaction are often studied in the totally symmetric space (TSS) of maximal total spin. However the TSS states are at…
Hydrodynamic electronic transport
Lars Fritz, Thomas Scaffidi
The ``flow'' of electric currents and heat in standard metals is diffusive with electronic motion randomized by impurities. However, for ultraclean metals, electrons can flow like…
