Unified gauge-theory description of quantum spin liquids on square-based frustrated lattices
Atanu Maity, Andreas Feuerpfeil, Ronny Thomale +2
Quantum spin liquids are commonly thought to be highly sensitive to lattice geometry, symmetry, and microscopic exchange patterns, leading to a proliferation of seemingly distinct…
Unifying Dirac Spin Liquids on Square and Shastry-Sutherland Lattices via Fermionic Deconfined Criticality
Andreas Feuerpfeil, Leyna Shackleton, Atanu Maity +3
We present a fermionic gauge theory for deconfined quantum criticality on the Shastry-Sutherland lattice and reveal its shared low-energy field-theoretic structure with the square…
Semi-Dirac spin liquids and frustrated quantum magnetism on the trellis lattice
Sourin Chatterjee, Atanu Maity, Janik Potten +7
Geometrical frustration in quantum magnets provides a fertile setting for unconventional phases of matter, including quantum spin liquids (QSLs). The trellis lattice, with its comp…
Evidence for a Dirac spin liquid in the generalized Shastry-Sutherland model
Atanu Maity, Francesco Ferrari, Sylvain Capponi +8
We present a multimethod investigation into the nature of the recently reported quantum spin liquid (QSL) phase in the spin- Heisenberg antiferromagnet on the Shastry-Sutherla…
Altermagnetic phase transition in a Lieb metal
Matteo Dürrnagel, Hendrik Hohmann, Atanu Maity +4
We analyze the phase transition between a symmetric metallic parent state and itinerant altermagnetic order. The underlying mechanism we reveal in our microscopic model of electron…
Gapped and gapless quantum spin liquids on the ruby lattice
Atanu Maity, Rhine Samajdar, Yasir Iqbal
The ruby lattice has been the subject of much interest recently due its realization in Rydberg atom arrays, where its rich variety of frustrated interactions gives rise to topologi…
