Phase space fractons
Ylias Sadki, Abhishodh Prakash, S. L. Sondhi +1
Perhaps the simplest approach to constructing models with sub-dimensional particles or fractons is to require the conservation of dipole or higher multipole moments. We generalize…
The Moving Born-Oppenheimer Approximation
Bernardo Barrera, Daniel P. Arovas, Anushya Chandran +1
We develop a mixed quantum-classical framework, dubbed the Moving Born-Oppenheimer Approximation (MBOA), to describe the dynamics of slow degrees of freedom (DOFs) coupled to fast…
Incommensurate gapless ferromagnetism connecting competing symmetry-enriched deconfined quantum phase transitions
Anthony Rey, Ãmer M. Aksoy, Daniel P. Arovas +2
We present a scenario, in which a gapless extended phase serves as a "hub" connecting multiple symmetry-enriched deconfined quantum critical points. As a concrete example, we const…
Quantum geometry and dipolar dynamics in the orbital magneto-electric effect
James H. Cullen, Daniel P. Arovas, Roberto Raimondi +1
We show that the orbital magneto-electric effect (OME) -- the generation of a steady-state orbital angular momentum density -- is partly the result of a nonequilibrium dipole momen…
Effects of non-integrability in a non-Hermitian time crystal
Weihua Xie, Michael Kolodrubetz, Vadim Oganesyan +1
Time crystals are systems that spontaneously break time-translation symmetry, exhibiting repeating patterns in time. Recent work has shown that non-Hermitian Floquet systems can ho…
Quantum correction to the orbital Hall effect
Hong Liu, James H. Cullen, Daniel P. Arovas +1
Evaluations of the orbital Hall effect (OHE) have only retained inter-band matrix elements of the position operator. Here we evaluate the OHE including all matrix elements of the p…
