Fun facts about me:


I am a third-year physics PhD candidate at the University of Michigan (UofM) and am also pursuing a math masters. My advisor is Dr. Kai Sun.

I obtained my B.S. degree in physics and mathematics with a minor in Hebrew from the University of Texas at Austin (UT Austin) in 2022.

My research focus is in condensed matter theory. More particularly, my research interests include non-Hermitian systems, curved-space lattices, and topological properties of solids.

Solids, at a first glance, might seem rather boring: they are objects that might be hard or flexible, conduct or insulate, and may or may not work well as a desk. But, despite restricting the motion of electrons to the well-structured positions of atoms on a lattice, solids host a rich variety of physics that (not all of which) is fully understood. In fact, the periodic lattice structure is responsible for many interesting properties of solids.

Topological phases have been rather popular in the last few decades. Usually, they are characterized by an insulating bulk yet have conducting edge states. More recently, advancements in quantum circuits have allowed lattices in hyperbolic space to be simulated. Hyperbolic lattices are incredibly diverse in structure in comparison to typical lattices in Euclidean space. These offer a new framework to discover and understand phases arising from the lattice structure of solids. On the other hand, non-Hermitian Hamiltonians, which may describe decaying systems, exhibit properties distinct from typical Hermitian Hamiltonians. In particular, eigenstates will exponentially localize at the edge of an open boundary; this is termed the non-Hermitian skin effect. Because of the non-Hermitian skin effect and unlike the Hermitian case, non-Hermitian systems are sensitive to the choice of boundary condition even in the thermodynamic limit.
